Answer:

6 units left and 4 up (if figure K translated)
6 units right and 4 units down (if figure J translated)

Step-by-step explanation:

It is not clear which of the figures is translated.

Assume it is figure K.

Use one of the points and compare the corresponding point.

If you take bottom-left point, then the difference is coordinates is:

-7 - (-1) = -6, this is translation left by 6 units (or right if the figure J is translated)
2 - (-2) = 4, this is translation up by 4 units (or down if the figure J is translated)

So the answer is

6 units left and 4 up or, (figure K translated)
6 units right and 4 units down (figure J translated)

Please help! will give brainliest Find the value of x. A. 74 B. 52 C. 64 D. 244

pickupchik [31]

Answer:

C. 64

Step-by-step explanation:

x° = 1/2[(360° - 2*58°) -2*58°]

x° = 1/2[(360° - 116°)- 116°]

x° = 1/2[244°- 116°]

x° = 1/2[128°]

x° = 64°

x = 64

Find the x- and y-intercepts of the graph of — 7x + 8y = 40. State your answers as

geniusboy [140]

Answer:

x-intercept is (40/7, 0) and y-intercept is (0, 5)

Step-by-step explanation:

x-intercept ==> y-coordinate is 0 ==> y=0

y-intercept ==> x-coordinate is 0 ==> x=0

because the function is 7x + 8y = 40

when y = 0 ==> 7x = 40 ==> x = 40/7

so the x-intercept is (40/7, 0)

when x = 0 ==> 8y = 40 ==> y = 5

so the y-intercept is (0,5)

Which of the following is equivalent to log432?

Lesechka [4]

Log base 4 of 32 is equal to 5/2.

What a log is looking for is what number do we have to raise 4 to in order to get 32. Since it is not an exact multiply of 4, we have to look for fractions. Since we know that 2 can multiply directly to 32, we would simply take the square root of 4. This can be done by raising 4 to the 1/2.

Now that we have 2, we know that raising that to the 5th power would give us 32. So we'll take that answer and the 1/2 from before and multiply them together to get the final answer.

5*1/2 = 5/2.

The weight of crackers in a box is stated to be 16 ounces. The amount that the packaging machine puts in the boxes is believed t

krek1111 [17]

Answer:

99.99% probability that the mean weight of a 50-box case of crackers is above 16 ounces

Step-by-step explanation:

To solve this question, we need to understand the normal probability distribution and the central limit theorem.

Normal probability distribution

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean $\mu$ and standard deviation $\sigma$ , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean $\mu$ and standard deviation $s = \frac{\sigma}{\sqrt{n}}$ .
