Answer:

Step-by-step explanation:

Use the equation

89 < 75 + 0.7*M Subtract 75 from both sides

89 - 75 < 0.7M Combine

14 < 0.7 M Divide both sides by 0.7

14/0.7 < M

20 < M

If M goes over 20 then the flat rate is cheaper.

Are these equations of lines parallel: Y=3X+4 and Y+3 = -3(-X+2)<br> NO<br> YES

Rzqust [24]

Answer:

yes

Step-by-step explanation:

Change the second equation into slope-intercept form: y+3=-3(-x+2)

Distribute the -3: y+3=3x-6

Isolate the y: y=3x-6-3

Simplify: y=3x-9

Since they have the same slope, they are parallel

How do you work out the size of angle x ?

Andreyy89

Answer:

117°

Step-by-step explanation:

Angle of straight line is 180°

Angles in a triangle add up to 180°

starting at right

180 - 101 = 79° at right side angle in triangle

now solving left side angle

180 - 38 - 79 = 63°

now solving x using left side angle, must add to 180°

x + 63 = 180°

x = 117°

The margin of error for 324 adults surveyed with 1.6 standard deviations is 0.1742.

<h3>What is the margin of error?</h3>

The margin of error can be defined as the amount of random sampling error in the results of a survey. It is given by the formula,

$\text{MOE}_{\gamma}=z_{\gamma} \times \sqrt{\frac{\sigma^{2}}{n}}$

$\text{MOE}$ = margin of error

$\gamma$ = confidence level

$z_{\gamma}$ = quantile

σ = standard deviation

n = sample size

As it is given that the sample size of the survey is 324, while the standard deviation of the survey is 1.6.

We know that the value of the z for 95% confidence interval is 1.96. Therefore, using the formula of the standard of error we can write it as,

$\text{MOE}_{\gamma}=z_{\gamma} \times \sqrt{\dfrac{\sigma^{2}}{n}}\\\\\text{MOE}_{\gamma}=1.96 \times \sqrt{\dfrac{1.6^{2}}{324}}\\\\\text{MOE}_{\gamma}=0.1742$

Hence, the margin of error for 324 adults surveyed with 1.6 standard deviations is 0.1742.
