The composition of two translations could describe the taxicab’s final position are (1, -2 + 16) and (1, -2 - 16)

<h3>How to determine the composition of two translations?</h3>

The initial position is given as:

Cab = (1, -2)

Assume the cab travel in one direction, the possible translations are:

(x, y + 16)

(x, y - 16)

(x  + 16, y)

(x  - 16, y)

Using the first two translations, the final positions are:

(1, -2 + 16) = (1, 14)

(1, -2 - 16) = (1, -18)

Hence, the composition of two translations could describe the taxicab’s final position are (1, -2 + 16) and (1, -2 - 16)

Suppose we are interested in analyzing the weights of NFL players. We know that on average, NFL players weigh 247 pounds with a
Diano4ka-milaya [45]

Answer:

a) The standard error would be of 8.58 pounds.

b) The margin of error is 14.11 pounds.

c) The 90% confidence interval for the population mean is between 232.89 pounds and 261.11 pounds

Step-by-step explanation:

a.What is the standard error?

The standard error is

s = \frac{\sigma}{\sqrt{n}}

In which \sigma is the standard deviation of the population and n is the size of the sample. So

s = \frac{47}{\sqrt{30}} = 8.58

The standard error would be of 8.58 pounds.

b.What is the margin of error at 90% confidence?

We have that to find our \alpha level, that is the subtraction of 1 by the confidence interval divided by 2. So:

\alpha = \frac{1-0.9}{2} = 0.05

Now, we have to find z in the Ztable as such z has a pvalue of 1-\alpha.

So it is z with a pvalue of 1-0.05 = 0.95, so z = 1.645

Now, find the margin of error M as such

M = z*s = 1.645*8.58 = 14.11

The margin of error is 14.11 pounds.

c. Using my sample of 30, what would be the 90% confidence interval for the population mean?

Lower bound: Sample mean subtracted by the margin of error.

247 - 14.11 = 232.89 pounds

Upper bound

247 + 14.11 = 261.11 pounds

The 90% confidence interval for the population mean is between 232.89 pounds and 261.11 pounds

Ronnie is thinking of a number. He says that he gets the same result when he multiplies by his number by 2 as when he adds 5 to
Anettt [7]
Let's say Ronnie is thinking of X.

If 2(x) = x+5, we would first distribute the 2.

2x = x+5

We would then need to isolate the variable. We would do so by getting all variables to one side. The easier choice would be to subtract x from both sides.

2x=x+5
-1x -1x

This becomes

x=5

Ronnie is thinking of the number five.

5•2=10 and 5+5=10.

Harold sorted his jellybeans into two jars. He likes the purple ones best and the black ones next best, so these are both in one
charle [14.2K]

Answer: 30%

The probability of black is 60% and the probability of orange is 50%. The probability of getting both is then the product of their probabilities:

                          60% multiplied by 50%=0.6 times 0.5=0.3 of 30%

HOPE THIS HELPS!!!!!!!:)
