Answer:

41

Step-by-step explanation:

Since a triangle is 180 degrees ans the triangle is on the right is equal to the triangle on the left, all you have to do is take 180 and subtract 86 and 53 from it to get 41. There's also the fact that the length of all the sides are the same so that can also mean that the angles are the same.

A manufacturer claims that fewer than 6% of its fax machines are defective. to test this claim, he selects a random sample of 97
AfilCa [17]

Let P be the population proportion, p be the sample proportion, n be the sample size.

A manufacturer claims that fewer than 6% of its fax machines are defective. It means P=0.06

Sample size n=97 and sample proportion p=0.05

The hypothesis to be tested is

H0: P ≥ 0.06 V/s Ha: P < 0.06

Here the hypothesis for testing population proportion we use z test statistics. Z test statistics is give by

Z = \frac{p -p_{0}}{\sqrt{p_{0}(1-p_{0})/n}}

Where p =sample proportion = 0.05

p0 = hypothesized proportion value =0.06

Using given values into test statistics we get

Z = \frac{0.05 -0.06}{\sqrt{0.06(1-0.06)/97}}

Z = -0.41

The p-value for left tailed alternative hypothesis is given by

P-value = P(z < z cal)

where zcal = Z test statistics value

Here zcal = -0.41

P-value = P(Z < -0.41)

Using z score table to find probability below z=-0.41

P-value = 0.3409

P-value for testing the given claim is 0.3409

Y = 2x + 3<br> 2y = 4x + 6<br><br> The system of equations has _____ solution(s).
Len [333]
Dividing the 2nd equation by 2 gives y=2x + 3 which is the same as the too
p line. any answer to one of them is obviously an answer to the other so there are infinitely many solutions

Lou eats 6/8 of pizza. what fraction of the pizza is left over?
AfilCa [17]
So, if the pizza is cut into 8 slices that would mean we just have to subtract 6 - 8 = 2 so your answer is 2/8 of the pizza is left

Hope this helped!

(I will mark brainliest) Will 3/8 + 2/8 be closer to 1/2 or 1? How do you know?
11111nata11111 [884]

Answer:

1/2

Step-by-step explanation:

3/8 + 2/8 is 5/8, 1/2 is equal to 4/8, so 5/8 is only 1/8 away from 1/2 while 5/8 is also 3/8 away from 1 or 8/8 therefore, it is closer to 1/2
