What is the equation of a line that passes through the points (-3, 4) and (2,8)?

ziro4ka [17]

Given that the line passes through the two points (-3,4) and (2,8)

We need to determine the equation of the line.

Slope:

The slope of the line can be determined using the formula,

$m=\frac{y_2-y_1}{x_2-x_1}$

Substituting the points (-3,4) and (2,8) in the above formula, we get;

$m=\frac{8-4}{2+3}$

$m=\frac{4}{5}$

Thus, the slope of the line is $m=\frac{4}{5}$

Equation of the line:

The equation of the line can be determined using the formula,

$y-y_1=m(x-x_1)$

Substituting the point (-3,4) and $m=\frac{4}{5}$ in the above formula, we have;

$y-4=\frac{4}{5}(x+3)$

$y-4=\frac{4}{5}x+\frac{12}{5}$

$y=\frac{4}{5}x+\frac{12}{5}+4$

$y=\frac{4}{5}x+\frac{32}{5}$

Thus, the equation of the line is $y=\frac{4}{5}x+\frac{32}{5}$

A group of 40 bowlers showed that their average score was 192. Assume the population standard deviation is 8. Find the 95% confi

kodGreya [7K]

Answer:

$CI=189.5,194.5$

Step-by-step explanation:

From the question we are told that:

Sample size $n=40$

Mean $\=x =192$

Standard deviation $\sigma=8$

Significance Level $\alpha=0.05$

From table

Critical Value of $Z=1.96$

Generally the equation for momentum is mathematically given by

$CI =\=x \pm z_(a/2) \frac{\sigma}{\sqrt{n}}$

$CI =192 \pm 1.96 \frac{8}{\sqrt{40}}$

$CI=192 \pm 2.479$

$CI=189.5,194.5$

Tires have a normal distribution with a mean of 70000 miles and a standard deviation of 4400 miles. What proportion of tires wil

yarga [219]

Let T = the distance, in miles, a tire lasts

T ~ N(70000,4400²)

P(T $\geq$ 75000)
= P(Z $\geq \frac{75000 - 70000}{4400}$ )
= P(Z $\geq \frac{25}{22}$ )
≈ P(Z $\geq$ 1.14)
= 1 - P(Z < 1.14)
≈ 1 - 0.8729
= 0.1271
