Answer:
(√17 + √2)/(√17 + √2)Step-by-step explanation:
You need to determine the conjugate of the denominator.
√17 - √2 has conjugate of √17 + √2, when multiplied the product is going to be a rational number:
(√17 - √2)/(√17 + √2) = 17 - 2 = 15Therefore correct choice is B or second from the top:

A pizza shop sells three sizes of pizza, and they track how often each size gets ordered along with how much they profit from each size. Let X represent the shop's profit on a randomly selected pizza. Here's the probability distribution of X along with summary statistics:
Small Medium Large
X = profit ($) 4 8 12
P(X) 0.18 0.50 0.32
Mean: μX = $8.56
Standard deviation: σx =$2.77
The company is going to run a promotion where customers get $2 off any size pizza. Assume that the promotion will not change the probability that corresponds to each size. Let Y represent their profit on a randomly selected pizza with this promotion. What are the mean and standard deviation of Y?
Answer:
The mean and standard deviation of Y is $6.56 and $2.77 respectively.
Step-by-step explanation:
Consider the provided information.
Let Y represent their profit on a randomly selected pizza with this promotion.
The company is going to run a promotion where customers get $2 off any size pizza.
Therefore, [tex]Y=\text{Profit}-\$2[/tex]
[tex]Y=X-\$2[/tex]
So the mean will be reduced by 2.
[tex]\mu_Y=\mu_X-\$2[/tex]
[tex]\mu_Y =\$ 8.56 - \$2[/tex]
[tex]\mu_Y =\$6.56[/tex]
If we add or subtract any constant number from a given distribution, then the mean is changed by the same number(i.e constant number) but the standard deviation will remain the same.
Therefore [tex]\sigma_Y=\sigma_X=2.77[/tex]
Hence, the mean and standard deviation of Y is $6.56 and $2.77 respectively.

Given system:
4x - 2y = 22x + y = - 51) Solving the second equation for y:
2x + y = - 5 ⇒y = -5 - 2x2) Substituting y into the first equation:
4x - 2y = 2 ⇒4x - 2( -5 - 2x) = 2Correct option is a)3) Solving for x:
4x - 2( -5 - 2x) = 24x + 10 + 4x = 28x = 2 - 108x = -8x = -14) Solving for y:
y = -5 - 2xy = -5 - 2(-1) = -5 + 2 = -3y = -35) Ordered pair is:

What is the equation of the line in slope-intercept form?
O Y=2x-8
O y = 2x+8
O y=8x-2
O y = 8x+2
Step-by-step explanation:
since b = 8, it has to be
y = 2x + 8
that was the whole point of the exercise, as the general slope-intercept form is
y = mx + b
you determined m = 2 and b = 8, so there is your answer. I am not sure where your problem was, as you solved the actual important part yourself.
a) In the first event, the eighth graders are running a baton relay race with three other classmates. The team’s top speed for each leg is 56.81 seconds, 59.22 seconds, 57.39 seconds, and 60.11 seconds. Use the information to predict the team’s best time for the race
Answer:
58.4 seconds
Step-by-step explanation:
Find the average of all the seconds by dividing the sum of the seconds by 4
Answer:
233.53 s
The sum of best times for the legs is ...
56.81 +59.22 +57.39 +60.11 = 233.53 . . . seconds
Without additional information about the effects of training or the normal variation in times, this is the best prediction we can make.

Find the measures of the numbered angles of the parallelogram.
Answer:
1=40
2=140
3=40
Step-by-step explanation:
We know on side
140 and side 2 are equal
1 and 3 are equal
So since 140 and 2 are equal
140*2=280
360 degrees total in any 4 sided shape
360-280=80
80/2=40
Determine whether the relation is a function. Explain. {(2,5),(4,−2),(3,3),(5,4),(−2,5)} *
No; the elements –2, 3, 4, and 5 are in both the domain and the range.
Yes; for each element of the range, there is only one element of the domain.
No; the element 5 occurs twice in the range.
Yes; for each element of the domain, there is only one element of the range.
Answer:
Yes; for each element of the domain, there is only one element of the range.
Step-by-step explanation:
A set (x,y) represents a function if for each value of x(domain), there is only one respective value of y(range).
In this question, yes, for each value of x(2,4,3,5,-2), there is only one respective value of y, so it represents a function.
The correct answer is given by:
Yes; for each element of the domain, there is only one element of the range.
