Answer:

3

Step-by-step explanation:

if the decimal is 5 or more then u round up to the next number

4 or below then it stays that number

Hey there!

Fun fact:

If it’s BIGGER than 5 (or equal to 5), you round UPWARD & if it’s SMALLER than 5, you go DOWNWARD.

2 is SMALLER than 5 & 7 is BIGGER than 5

Thus, your answer should be: [3]

The probability of selecting the card with the number three at least once is 1/10.

Given that,

1 through 10 cards are contained in a box. Two cards are chosen at random and replaced

To find : The probability of selecting the card with the number three at least once?

Probability (3 at first)  * Probability (3 at second) + Probability (3 at first)  *Probability (others at second) + Probability (others at first) *Probability (3 at second) = 1/10 * 1/0 + 1/10 *9/10 + 9/10*1/10

= 19/100 = 0.19

Here there are 10 cards,

So, probability of picking three is 1/10 and probability of picking others is 9/10

270 degrees

Step-by-step explanation:

Description: This lesson will explain that of the 360 degree full rotation of a circle, 3/4 of a rotation is 270 degrees.

Answer:

Three squared is 9 because 3*3=9 so therefore it is also the square root of 9

So the relationship is that 3 squared is 9 and the square root of 9 is 3

Answer:

r = 19 ft

Step-by-step explanation:

Circumference, C is given as 119.32 ft

Circumference of a circle is given by the formula, 2πr

This means that,

C = 2πr, we're told to assume that π = 3.14

So therefore,

119.32 = 2 * 3.14 * r

r = 119.32 / 6.28

r = 19 ft

2) (2,1)

Answer:

f(x) = -1/x^2 + 4e^x + 5x + 1 + 1/x - 4e^(-1)

Step-by-step explanation:

We can find the function f(x) by integrating f'(x) with respect to x:

â«f'(x) dx = â«(2/(x^3) + 4e^x + 5) dx

f(x) = -1/x^2 + 4e^x + 5x + C

To find the constant C, we can use the given initial conditions:

f(-1) = 1 = -1/(-1)^2 + 4e^(-1) - 5 + C

C = 1 + 1/1 - 4e^(-1)

f(x) = -1/x^2 + 4e^x + 5x + 1 + 1/x - 4e^(-1)

Therefore, the function f(x) is:

f(x) = -1/x^2 + 4e^x + 5x + 1 + 1/x - 4e^(-1)

Answer:

x=62

Step-by-step explanation:

(x+1)+ x+55=180

-55               -55 (take away the 55)

(x+1)+ x= 125 (take out of parenthesis)

x+1+ x= 125

2x+ 1= 125  (add the two x's together)

-1         -1        (take away the one)

2x= 124  (divide by 2)

x=62

The mean of the probability distribution is 21.35 and the variance of the probability distribution is 51.3275

Given the probability distribution with values of x and corresponding P(x). We need to find the values of \(x^2\), x P(x), \(x^2\) P(x) to calculate mean and variance.

x       P(x)          \(x^2\)      x P(x)      \(x^2\) P(x)

7       0.10         49       0.7         4.9

28     0.45        784     12.6       352.8

-----------------------------------------------------

∑x P(x) = 21.35

∑\(x^2\) P(x) = 507.15

Mean = ∑x P(x) = 21.35

83 boxes are required to carry 800 books.

According to the question:

One Box can hold weight = 30 pounds

We know that ,  1 pound= 0.45 kg

hence, 30 pounds = 30 x 0.45 = 13.5kg  

hence,  one box can carry 13.5 kg of weight.

Now,

Weight of 1 book = 1.4 kg

So, Total Weight of 800 books= 1.4 x 800 kg

And , No. of boxes required to carry 800 books = (1.4 x 800)/13.5 = 82.96

                                                                             or approximately 83 boxes

Hence, 83 boxes are required to carry 800 books.

The equivalent ratio of form 1 : n is 1 : 4.5

Here the ratio given is 6 : 27 and we have to convert this ratio into the form of 1 : n.

6: 27

= 6/27

Divide the numerator and the denominator by 6, then we get

1 / (27/6)

= 1/ 4.5

Which is equivalent to the ratio 1 : n.

Therefore the equivalent ratio is 1 : 4.5.

Step-by-step explanation:

Answer: £900

Step-by-step explanation:

He should order 10 sandwiches of 6 foot long so, as to make sure that everyone will eat 2 pieces.

We need to convert between the units in order to ensure the accuracy and to prevent measurement misinterpretation. For example, we do not measure the pencil's length in kilometres. In this situation, one must convert from kilometres (km) to centimetres (cm) (cm). In most cases, multiplicative conversion factors are used to convert one unit to another of the same quantity. Let's see how to change the length and mass units.

1 Feet = 12 Inches

So, 6 Foot = 72 inches

The Length of sandwich- piece is 4 inch

So, when we convert 6 foot long sandwich into 4 inch,

Then we get number of piece is = 72/4 = 18

From 6 foot long sandwich we get 18 pieces of 4 inch long sub.

Now, Total people who will attend picnic is 40

and each people will eat 2 pieces.

It means total number of piece required = 2 (90) = 180

Mr. eaton required 180 pieces of sandwiches.

Number of sandwiches = 180 / 1.8 = 10

He should order 10 sandwiches of 6 foot long.

The angle θ calculated from the range r of the projectile  is 11.2 degrees.

To find the angle θ when the range r of a projectile is given by r = 1/32 v0^2 sin(2θ), we can use the following steps:

Start with the given equation r = 1/32 v0^2 sin(2θ). Isolate the sin(2θ) term by dividing both sides of the equation by 1/32 v0^2. This gives us sin(2θ) = 32r/v0^2. Take the inverse sine of both sides of the equation to find 2θ. This gives us 2θ = sin^-1(32r/v0^2). Divide both sides of the equation by 2 to find θ. This gives us θ = sin^-1(32r/v0^2)/2. Now we can plug in the given values of r and v0 to find the angle θ.

r = 300 ft
v0 = 115 ft/s
θ = sin^-1(32(300)/(115)^2)/2
θ = sin^-1(32(300)/(13225))/2
θ = sin^-1(0.729)/2
θ = 22.4/2
θ = 11.2 degrees

Step-by-step explanation:

Sample mean in sample b to be less variable and more representative of  population mean than sample mean in sample a.

Standard error measures the variability of sample means around the population mean.

It decreases as sample size increases.

Using the formula for the standard error of the mean,

Calculate the standard errors for each sample,

Standard error of sample a

= s/√(n)

= 850/√(9)

= 283.33

Standard error of sample b

= s/√(n)

= 850/√(36)

= 141.67

Where s is the sample standard deviation

And n is the sample size.

The standard error of sample b is smaller than the standard error of sample a.

Sample mean in sample b is more likely to be closer to true population mean than sample mean in sample a.

Therefore, sample mean b is more surprising as larger sample size makes it more likely and accurately represents population mean.
