Answer:
Step-by-step explanation:
7 more than the product of 8 times 9
product of 8 times 9 = 8 × 9 = 72
7 more than the product of 8 times 9 = 72 + 7 = <u><em>79</em></u>

The <em>correct answer</em> is:
Translation.
Explanation:
A translation is a "slide" of a figure. Since it "slides" the figure, it moves every point the same direction and the same distance.
Since the size and shape of the figure is preserved, a translation is an isometry.
Answer: just graph these two equations
option a: y = 5x + 10
option b: y = 7.5x
and then tell at what number of event would having a card and not having a card is cheaper.
Step-by-step explanation:
the initial cost, $10, is your b value for the equation y = mx + b so yo would start here on the y axis. but for the second option you start at zero since you don't have a b value
Answer:
There is not enough statistical evidence to state that the mean score on one-tailed hypothesis test questions is higher than the mean score on two-tailed hypothesis test questions.
Step-by-step explanation:
To solve this problem, we run a hypothesis test about the difference of population means.
The appropriate hypothesis system for this situation is:
![H_0:\mu_X-\mu_Y=0\\H_a:\mu_X-\mu_Y > 0\\\\$Difference of means in the null hypothesis is:\\\mu_X-\mu_Y=M_0=0\\\\$The test statistic is $Z=\frac{[( \bar X-\bar Y)-M_0]}{\sqrt{\frac{\sigma^2_X}{n_X}+\frac{\sigma^2_Y}{n_Y}}}\\](https://tex.z-dn.net/?f=H_0%3A%5Cmu_X-%5Cmu_Y%3D0%5C%5CH_a%3A%5Cmu_X-%5Cmu_Y%20%3E%200%5C%5C%5C%5C%24Difference%20of%20means%20in%20the%20null%20hypothesis%20is%3A%5C%5C%5Cmu_X-%5Cmu_Y%3DM_0%3D0%5C%5C%5C%5C%24The%20test%20statistic%20is%20%24Z%3D%5Cfrac%7B%5B%28%20%5Cbar%20X-%5Cbar%20Y%29-M_0%5D%7D%7B%5Csqrt%7B%5Cfrac%7B%5Csigma%5E2_X%7D%7Bn_X%7D%2B%5Cfrac%7B%5Csigma%5E2_Y%7D%7Bn_Y%7D%7D%7D%5C%5C)
![$$The calculated statistic is Z_c=\frac{[(7.79-7.64)-0]}{\sqrt{\frac{1.06^2}{80}+\frac{1.31^2}{80}}}=0.79616\\\\p-value = P(Z \geq Z_c)=0.42594\\\\](https://tex.z-dn.net/?f=%24%24The%20calculated%20statistic%20is%20Z_c%3D%5Cfrac%7B%5B%287.79-7.64%29-0%5D%7D%7B%5Csqrt%7B%5Cfrac%7B1.06%5E2%7D%7B80%7D%2B%5Cfrac%7B1.31%5E2%7D%7B80%7D%7D%7D%3D0.79616%5C%5C%5C%5Cp-value%20%3D%20P%28Z%20%5Cgeq%20Z_c%29%3D0.42594%5C%5C%5C%5C)
Since, the calculated statistic 
is less than critical 
, the null hypothesis do not should be rejected. There is not enough statistical evidence to state that the mean score on one-tailed hypothesis test questions is higher than the mean score on two-tailed hypothesis test questions.
Make the equation a little more descriptive
