Answers
Answer: Point B
Reason:
This point is the highest point in the neighborhood or interval. Yes point D is higher up, but points immediately adjacent to point D are higher. This means D is not a relative max. We need a hill shape like where B is located. In contrast, point C is a relative minimum since it is at the bottom of the valley.

A produce manager inspects large truckloads of potatoes to determine the proportion with major defects (p). She intends to compute a 95% confidence interval for p. To do so, she selects an SRS of 50 potatoes from the more than 2,000 potatoes in the truck. Suppose that only 2 potatoes sampled are found to have major defects.
1. The P-value of her test is:_____.
a. 0.4082.
b. 0.0918.
c. 0.0400.
d. less than 0.0002.
2. Which of the assumptions for inference about a proportion are violated?
a. the data are an SRS from the population of interest.
b. the population is at least 10 times as large as the sample.
c. n is so large that both np0 and n(1-p0) are 10 or more, where p0 is the proportion with major defects if the null hypothesis is true.
d. there appear to be no violations.
3. A 95% plus four confidence interval for the true proportion of potatoes in the truck that have major defects is:____.
a. 0.06±0.026.
b. 0.06±0.051.
c. 0.077±0.026.

Answers
Answer:
x = 2
y = 1
Step-by-step explanation:
-2x-3y=-7, y=6x-11
-2x - 3(6x - 11) = -7
-2x - 18x + 33 = -7
-2x - 18x = -40
-20x = -40
x = 2
y = 6(2) - 11
y = 12 - 11
y = 1
Answer:
x = 2, y = 1
Step-by-step explanation:
We have a system of equations:
-2x - 3y = -7
y = 6x - 11
Substitute the given value of y into the equation -2x - 3y = -7
-2x - 3 * (6x - 11) = -7
-20x = -7 - 33
-20x = - 40
x = 2
Substitute the given value of x into the equation y = 6x - 11
y = 6x - 11
y = 6 * 2 - 11
y = 1

The third leg of the right-angle triangle will be 12 cm.
What is a right-angle triangle?It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.
The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.
The Pythagoras theorem formula is given as
H² = P² + B²
The hypotenuse of the right-angle triangle is 13 cm and the perpendicular of the right-angle triangle is 5 cm.
Then the measure of the third side (B) of the right-angle triangle will be
13² = 5² + B²
169 = 25 + B²
B² = 169 - 25
B² = 144
B = 12
Thus, the third leg of the right-angle triangle will be 12 cm.

In a shop, there were 4 times as many guppies as swordtails. After 23 guppies and 27 swordtails were added, there were 83 more guppies than swordtails. What was the total number of fish in the shop at first?
Answers
Answer:
145
Step-by-step explanation:
Assume the number of sword tails is x. Then the number of guppies is 4x.
After 23 guppies and 27 swordtails were added. Then guppies = 4x+ 23
swordtails = x+27
According to the relation 83 more guppies than swordtails. We can obtain:
[tex]4x + 23 = x + 27 + 83[/tex]
4x-x= 27+83-23
3x=110-23
3x=87
x=29
There are 5x fish in total at first.
5x=5*29=145
so the number of fish in the shop at first is 145

Step-by-step explanation:
The table is showing 4 x and y values. With the question of which equation gives the rule of the table.
To solve, all we have to do is plug in x with the correspondant equation, same goes with y.
y = x + 11 will be the only one that fits mainly because all the other ones gives a higher result.
Answer:
y = x + 11
Step-by-step explanation:
y + 11 = 11
1 + 11 = 12
2 + 11 = 13
3+ 11 = 14
4+ 11 = 15
y is the first row, 1,2,3,and 4
11 is 11 (lol)
x is the answer
your answer is y=x+11
