Mathematics
1 answer:
Oksanka [162]3 years ago
5 0

Step-by-step explanation:

we have

m∠3 = 128°

m∠3 = m∠7---------------- > Corresponding Angles

180°=m∠7+m∠8---------- > Supplementary Angles

therefore

m∠8=180°-128°=52°

the answer is the m∠8 is 52°

balandron [24]

Answer:

<em>The first step is to determine the average </em>

x= \frac{0,6+0,7+ 0,7+0,3+0,4+ 0,5+ 0,4 +0,2}{8}\\\ x= 0,475

<em>The exercise says it’s a normal distribution: (n=8)</em>

s^{2}= \frac{1}{n-1} ((0,6.x)^2+2(0,7-x)^2+(0.3-x)^2+2(0.4-x)^2+(0.5-x)^2+(0.2-x)^2)\\\ \frac{1}{7}*0,235 = 0,0336 \\\\ s= 0183

<em>According to the exercise, the mean is equal to 0,5 then the value of t of the distribution can be obtained </em>

<em />

t= \frac{x-u}{\frac{s}{\sqrt{n} }}\\\ t= \frac{0,475 - 0,5}{0,183}\\\  t= -0,3860

<em>The variable t has 7 grade to liberty, we calculate the p-value as: </em>

2* P(t < - 0,3860)= \\\ 2* 0,3554 = 0,7108

This value is very high, therefore the hypothesis is not rejected

Natali5045456 [20]

Answer:

7 is the greatest number of bags Jason can fill.

Step-by-step explanation:

Given: Jason has 14 raspberry scones and 35 blackberry scones.

Now, finding the maximum number of bags Jason can fill with equal number of raspberry scones and blackberry scones.

∴ we will be using Greatest common factor (GCF) for knowing the number of bags.

14 = 2\times 7\\\\35= 5\times 7

∴ GCF= 7

7 is the greatest number of bags that Jason can fill with equal number of raspberry and blackberry scones.
