Null hypothesis is that the proportion of Americans who own a cellular phone is less than or equal to 0.82 (H0: p ≤ 0.82), and the alternative hypothesis is that the proportion of Americans who own a cellular phone is greater than 0.82 (Ha: p > 0.82).b. We know that the sample size is 1036 and the sample proportion is 881/1036 = 0.85. Therefore, the conditions to perform a z-test are met:np = 1036 × 0.82 ≈ 848.5 and n(1 - p) = 1036 × 0.18 ≈ 186.5Both are greater than 10. So, we can proceed with the z-test.

The null and alternative hypotheses. H0: p ≤ 0.82 Ha: p > 0.82.The conditions are met to perform a z-test, we can use the following criteria:np≥10 and n(1−p)≥10where n is the sample size and p is the hypothesized proportion of successes in the population.Assuming a significance level of 0.05, we are testing the claim that the percentage of Americans who own a cellular phone is equal to 82% or higher. Therefore, our null hypothesis is that the proportion of Americans who own a cellular phone is less than or equal to 0.82 (H0: p ≤ 0.82), and the alternative hypothesis is that the proportion of Americans who own a cellular phone is greater than 0.82 (Ha: p > 0.82).b. We know that the sample size is 1036 and the sample proportion is 881/1036 = 0.85. Therefore, the conditions to perform a z-test are met:np = 1036 × 0.82 ≈ 848.5 and n(1 - p) = 1036 × 0.18 ≈ 186.5Both are greater than 10. So, we can proceed with the z-test.

Answer:

The minimum value of C is 14

Step-by-step explanation:

Sketch the graph of the constraints using

2x + y = 20

with intercepts (0, 20) and (10, 0)

2x + 3y = 36

with intercepts (0, 12) and (18, 0)

The solution to both are above the lines

Solve 2x + y = 20 and 2x + 3y = 36 to find the point of intersection at (6, 8)

Then the coordinates of the vertices of the region formed are

(0, 20), (6, 8) and (18, 0)

Evaluate the objective function at each vertex to determine minimum value

C = 0 + 20 = 20

C = 6 + 8 = 14

C = 18 + 0 = 18

Thus the minimum value of C is 14 when x = 6 and y = 8

The best answer regarding the effects of carbon monoxide is option c, CO results in less oxygen loading hemoglobin but unloading is not changed.

Carbon monoxide binds up more tightly to the hemoglobin as compared to the oxygen molecules. This reduces the oxygen-carrying capacity of the blood and results in less oxygen loading onto hemoglobin.

However, once oxygen is already bound to hemoglobin, CO does not significantly affect its release or unloading. Therefore, option c is the most accurate statement among the given choices.

Step-by-step explanation:

The cost of purchasing 2 pounds of sliced ham and 3 pounds of sliced turkey from the meat counter is $30.95.

The table provided shows the purchases made by two customers at a meat counter. To determine how much you will pay for 2 pounds of sliced ham and 3 pounds of sliced turkey, you need to first look at the prices listed in the table. For sliced ham, the price per pound is $4.99, and for sliced turkey, the price per pound is $6.99.

To calculate the cost of 2 pounds of sliced ham, you can multiply the price per pound ($4.99) by the number of pounds (2), which gives you a total cost of $9.98. Similarly, to calculate the cost of 3 pounds of sliced turkey, you can multiply the price per pound ($6.99) by the number of pounds (3), which gives you a total cost of $20.97.

Therefore, the total cost for 2 pounds of sliced ham and 3 pounds of sliced turkey would be $9.98 + $20.97 = $30.95.

In conclusion, by using the prices listed in the table, it is possible to determine the cost of purchasing 2 pounds of sliced ham and 3 pounds of sliced turkey from the meat counter. It is important to remember to multiply the price per pound by the number of pounds needed for each item, and then add the costs together to get the total price.

A curvilinear term in mathematics is "Consisting of, bounded by, or characterized by a curved line." However, the definition of a quadratic is a second-order polynomial equation in a single variable \(0= ax^{2}+bx+c\) with

\(a\neq 0\). A quadratic is a curvilinear term according to my definition, but a function like \($x^{4}$\) would also fit the definition of curvilinear. So, your answer is

False, a quadratic and a curvilinear term are not the same.

What is set ?

A set is the mathematical model for a collection of different things; a set contains elements or members, which can be mathematical objects of any kind: numbers, symbols, points in space, lines,etc.

a) The set c = {north america, south america, europe, asia, australia, africa, antarctica} can be written in set-builder notation as:

c = {x | x is a continent and x ∈ {north america, south america, europe, asia, australia, africa, antarctica}}

b) The set-builder notation can be read as "the set c, such that x is a continent and x is an element of the set {north america, south america, europe, asia, australia, africa, antarctica}".

Based on the given information, it is unclear what type of data transformation has been performed. It is difficult to determine whether the technical condition of having approximately equal population standard deviations across each group has been satisfied.

However, if the data transformation has not significantly altered the standard deviations of the original data, then it is possible that this technical condition has been met. A statistical test, such as Levene's test, can be used to assess whether the assumption of equal variances has been violated. If the p-value from this test is greater than the significance level (e.g., 0.05), then we can conclude that there is no evidence to suggest that the population standard deviations are significantly different between groups.

Overall, without more information about the type of data transformation and the results of statistical tests, it is difficult to definitively state whether the technical condition has been satisfied on the transformed data.

Answer:

\(y_1 = -2\) and \(y_2 = 4\)

Step-by-step explanation:

\( \sqrt{10y + 24} - 3 = y + 1\)

Move the constant to the right-hand side and change their sign.

\( \sqrt{10y + 24} = y + 1 + 3 \)

combine like terms

\( \sqrt{10y + 24} - 3 = y + 4\)

Square both side to remove square brackets.

10y + 24 - 3 = y²+ 8y + 16

Move the expression to the left-hand side and change its sign.

10y + 24 - y² - 8y - 16 = 0

Combine like terms

10y - 8y + 24 - 16 - y² = 0

2y + 8 - y² = 0

Use commutative property to reorder the terms.

-y² + 2y + 8 = 0

Change the sign of expression.

y² -2y -8 = 0

split -2y

y² + 2y - 4y - 8 = 0

Factor out y from the first pair and -4 from the second equation.

y ( y + 2 ) - 4 ( y + 2 ) = 0

Factor out y+2 from the expression.

( y + 2 ) ( y - 4)

When the products and factors equals 0, at least one factor is 0.

y + 2 = 0

y - 4 = 0

Solve for y

y = -2

y = 4

When we plug the both solution as y we found that both is true solution of this equation.

This equation has two solutions which are -2 and 4.

Answer:

Solution given:

\( \sqrt{10y + 24} - 3 = y + 1\)

keep the constant term in one side

\( \sqrt{10y + 24} =y+1+3\)

solve possible one

\(\sqrt{10y+24}=y+4\)

now

squaring both side

\((\sqrt{10y+24})²=(y+4)²\)

10y+24=y²+8y+16

taking all term on one side

10y+24-y²-8y-16=0

solve like terms

8+2y-y²=0

doing middle term factorisation

8+4y-2y-y²=0

4(2+y)-y(2+y)=0

(2+y)(4-y)=0

y=-2

The probability that the digit 7 doesn't appear among 100 digits is 9/10, or 90%.

The probability that the digit 7 doesn't appear among 100 digits where each digit is one of (0-9) and all sequences are equally likely is given by the probability that all 100 digits are chosen from the set {0, 1, 2, 3, 4, 5, 6, 8, 9}. There are 10 choices for each digit, so there are 10^100 possible sequences of 100 digits. The number of sequences that don't contain the digit 7 is 9^100. Therefore, the probability that the digit 7 doesn't appear among 100 digits is: P(7 doesn't appear) = (9^100) / (10^100) = 9 / 10

Therefore, the probability that the digit 7 doesn't appear among 100 digits is 9/10, or 90%.

The answer after rounding is 36

Answer:

  an = 22 -6(n -1)

Step-by-step explanation:

The first term of the sequence is given as a1 = 22. The general term of an arithmetic sequence is ...

  an = a1 +d(n -1) . . . . n-th term for first term a1 and common difference d

The third term will be ...

  a3 = 10 = 22 +d(3 -1)

Then the common difference is ...

  10 -22 = 2d

  -12/2 = d = -6

__

Putting the known values into the formula for the general term, it becomes ...

  an = 22 -6(n -1)

__

This can be simplified to ...

  an = 28 -6n
