Step-by-step explanation:

If you think about this, we can figure out that 66 is 2/3 of 99.

To find out what 2/3 of 125 is, we can divide 125 by 3.

125 ÷ 3 = 41.6666667

Now multiply that by 2:

41.6666667 × 2 =83.3333334

The probability that the number pyramid will land on three and the spinner will stop on blue is 1/24.

To determine the probability that the number pyramid will land on three and the spinner will stop on blue, we need to know the total number of possible outcomes for both events and the number of favorable outcomes for the desired outcome.

Let's assume that the number pyramid has six sides numbered from one to six, and the spinner has four sections colored blue, red, green, and yellow. If both the number pyramid and spinner are fair and unbiased, each outcome is equally likely.

Number pyramid outcomes: There are six possible outcomes, namely numbers one to six.

Spinner outcomes: There are four possible outcomes, namely blue, red, green, and yellow.

To find the probability of both events happening together, we need to multiply the probabilities of each event occurring individually, assuming they are independent events (i.e., the outcome of one event does not affect the outcome of the other).

Probability of landing on three: Since the number pyramid has six sides, and we want to land on three, there is only one favorable outcome (three) out of the six possible outcomes. Therefore, the probability of landing on three is 1/6.

Probability of stopping on blue: Since the spinner has four sections, and we want it to stop on blue, there is only one favorable outcome (blue) out of the four possible outcomes. Therefore, the probability of stopping on blue is 1/4.

To find the probability of both events occurring, we multiply these probabilities:

Probability of landing on three and stopping on blue = (1/6) * (1/4) = 1/24

Therefore, the probability that the number pyramid will land on three and the spinner will stop on blue is 1/24.

The probability that the average score of the golfers exceeded 62 = 0.0228

Given the mean score of all golfers, μ = 72

and the Standard Deviation, σ = 4

Number of golf players, n = 64

We have to find the probability that the average score of the golfers exceed 73. i.e., x = 73

This follows the Normal Distribution.

Hence the z-score, Z = (x - μ)/(σ/√n)

                                   = (73 - 72)√64/4

                                   = 2

Probability that the average score of the golfers exceeded 73 = P(Z > 2)

                                                                                                        = 0.0228 [from the z-tables]

The region enclosed by the curves y = x, y = 3x, and y = -x + 4 needs to be sketched, and its area should be found.

To sketch the region enclosed by the curves, we need to plot the three given curves on a coordinate plane. The first curve is y = x, which represents a straight line passing through the origin (0,0) with a slope of 1. The second curve is y = 3x, which is also a straight line passing through the origin but with a steeper slope of 3. The third curve is y = -x + 4, which represents a line with a y-intercept of 4 and a negative slope of -1. By plotting these three lines on the same coordinate plane, we can see that they intersect at three points: (0,0), (1,3), and (3,1). The region enclosed by these curves is a triangular region with vertices at these three points. To find the area of this triangular region, we can use the formula for the area of a triangle: A = (1/2) * base * height. Let's draw the graph:

     |

   4 |         .  (2, 2)

     |      .

     |   .

     | .

   0 |_____________________

     0     1     2     3     4     5     6

In this graph, the first equation (y = x) is depicted by a diagonal line passing through the origin (0,0). The second equation (y = 3x) is a steeper line, while the third equation (y = -x + 4) is a downward-sloping line with a y-intercept of 4. In this case, the base of the triangle is the distance between the points (0,0) and (3,1), which is 3 units. The height of the triangle is the distance between the point (1,3) and the line y = -x + 4, which is also 3 units. Substituting these values into the area formula, we get A = (1/2) * 3 * 3 = 4.5 square units.

x = -20/7,u= -75/7

Step-by-step explanation:

Answer:

1) x = 14

2) x = 25

Step-by-step explanation:

1)

3x - 2 + 50 = 90

3x + 48 = 90

3x = 42

x = 14

2)

4x + 2 + 78 = 180

4x + 80 = 180

4x = 100

x = 25

Answer:

x = 21

Step-by-step explanation:

If lines AB and CD are parallel, then we can assume that m<5 and m<6 are supplementary that is the sum of both angles is 180degrees

Hence;

3x - 31 + 148 = 180

3x + 117 = 180

Subtract 117 from both sides

3x+117-117 = 180 - 117

3x = 180 - 117

3x = 63

x = 63/3

x = 21

Hence the value of x will be 21 if both angles are supplementary

A certain planet travels around it’s star in a nearly circular orbit with a radius of 185 million miles. The orbital speed of the planet is  78,558 miles / hour

The formula for the circumference of a circle is given by:

C = 2πr

Where:

r = radius of the circle

In the given problem:

r = 185 million miles

The distance of the planet's orbit is equal to the circumference of the orbit. Hence,

C = 2 x 22/7 x 185 million miles

  = 1,163 million miles

Assuming that a year in this planet is equal to 365 days and a day = 24 hours, then the amount of time that the planet needs to travel 1,163 million miles is

t = 1.69 years = 1.69 x 365 x 24

 = 14,804.4 hours.

Therefore, its orbital speed is:

Speed = distance / time

           =  1,163 million miles / 14,804.4 hours

           = 78,558 miles / hour

Given statement solution is :- a) If the sample was biased or not representative of the overall student population (e.g., only students from specific grades or majors), the estimate may not accurately reflect the percentage of students in the entire school who study at least two hours per night.

b) To estimate the average per capita income for the world, a more representative and comprehensive sampling approach would be necessary.

c) It's worth noting that the data is quite outdated (from 1996), and societal opinions and attitudes may have changed significantly since then. So, while the generalization might have been reasonable at the time of the poll, it may not accurately reflect the current population's views on social spending.

a) For situation (a), it depends on the sampling method used and the representativeness of the sample. If the sample was selected randomly from the entire student population of your school and the sample size is sufficiently large, then it is reasonable to generalize the estimate to the population. However, if the sample was biased or not representative of the overall student population (e.g., only students from specific grades or majors), the estimate may not accurately reflect the percentage of students in the entire school who study at least two hours per night.

b) In situation (b), it is not reasonable to generalize from the average annual income of ambassadors to the United Nations to estimate the average per capita income for the world as a whole. Ambassadors to the United Nations represent specific countries and their income may not be representative of the income levels of the entire global population. Global income distribution is highly varied, with significant disparities between different countries and regions. To estimate the average per capita income for the world, a more representative and comprehensive sampling approach would be necessary.

c) Situation (c) involves a Gallup poll conducted in 1996, which sampled 235 U.S. residents ages 18 to 29 to estimate the percentage of all U.S. residents ages 19 to 29 who favored cuts in social spending. In this case, the generalization from the sample to the population is reasonable only if the sampling method used was unbiased and the sample was representative of the entire population of U.S. residents ages 19 to 29. However, it's worth noting that the data is quite outdated (from 1996), and societal opinions and attitudes may have changed significantly since then. So, while the generalization might have been reasonable at the time of the poll, it may not accurately reflect the current population's views on social spending.

Answer:

There will need to be 2 and 1/3 cups of flour according to the recipe

Step-by-step explanation:

Given the recipe, we can say that for each 2 and 2/3s cups of milk, one cup of flour is used. We can write this as ( 2 + 2/3)  cups of milk / (1) cup of flour.

We can also write 2 + 2/3 as 2*(3/3) + 2/3 = 6/3 + 2/3 = 8/3, making our ratio

(8/3) / 1

The ratio stays the same, no matter how many cups of milk or flour are used. Therefore, (8/3) /1 = (4 + 2/3) / cups of flour

Writing our final cups of flour as c, we can say

(8/3) / 1 = (4+2/3) / c

(4+2/3)/c = (12/3 + 2/3) /c = (14/3) /c

(8/3)/1 = (14/3) /c

anything divided by 1 is equal to itself

(8/3) = (14/3)/c

multiply both sides by c to make the variable not a denominator

(8/3) * c = 14/3

multiply both sides by 3 to remove the denominators

8 * c = 14

divide both sides by 8 to isolate the c

c = 14/8 = 7/3 = 6/3 + 1/3 = 2 + 1/3

There will need to be 2 and 1/3 cups of flour according to the recipe

Answer: A reflect the graph of f across the y-axis

Answer:

Step-by-step explanation:

a) In an inverse proportion, as one variable increases, the other variable decreases in a way that their product remains constant.

The correct graph for an inverse proportion would show a curve that approaches the x-axis but never touches it. This curve represents the decreasing relationship between y and x.

b) To find the value of y when x = 4, we can use the given information.

Given:

y is inversely proportional to x

When x = 2, y = 1/2

In an inverse proportion, we can write the equation as:

y = k/x

To find the constant of proportionality (k), we can substitute the values (x, y) = (2, 1/2) into the equation:

1/2 = k/2

k = 1

Now that we have the value of k, we can use it to find y when x = 4:

y = k/x

y = 1/4

Therefore, when x = 4, y = 1/4.
