Mathematics
1 answer:
Otrada [13]3 years ago
6 0

Answer:

arc GM = 77°

Step-by-step explanation:

full circle = 360°

arc GMH = arc GNJ, so:

arc GMH = (360°- 52°)/2 = 154°

because line MP is perpendicular to line GH, arc GM = arc MH

arc GM = 154°/2 = 77°

Lapatulllka [165]

Answer:

the  height is :  2365.48  m

Step-by-step explanation:

hello :

h(t) = − 4.9 t 2 + 211 t + 94 .

the vertex of this parabola is : (-b/2a  , h(-b/2a) when : a= -4.9  and b=211

-b/2a = -(211)/2(-4.9) = 21.53

h(21.53) = -4.9(21.53)²+211(21.53)+94 = 2365.48  m

natali 33 [55]

Answer:

98% confidence interval: (29.25,38.87)

Step-by-step explanation:

We are given the following in the question:

Sample mean, \bar{x} = 34.06

Sample size, n = 134

Sample standard deviation, s = 23.83

a) 98% confidence interval

\bar{x} \pm z_{critical}\displaystyle\frac{s}{\sqrt{n}}  

Putting the values, we get,  

z_{critical}\text{ at}~\alpha_{0.02} = \pm 2.33  

34.06 \pm 2.33(\frac{23.83}{\sqrt{133}} ) = 34.06 \pm 4.81 = (29.25,38.87)

b)  If a 95% confidence interval were constructed with these data, confidence interval would be narrower as the confidence level is decreasing as compared to 98%

c)  If a sample of 150 students had been studied, the width of confidence interval will decrease as the sample size increases.

This question is the on I need help with
allsm [11]

let's recall that there are 16oz in 1 lbs, so then 12lbs is 12*16 = 192oz, plus 5, that makes it 197oz, so then 12lb 5oz is really 197oz.

likewise, 7lb is 7*16 = 112oz, plus 10 that makes it 122oz.

197 - 122 = 75 oz

and 75 oz is just 16+16+16+16+11, 4lbs and 11 oz.
