Bumek [7]

Answer:

0

Step-by-step explanation:

H0 : μ = 840

H1 : μ < 840

Sample size, n = 49

Standard deviation, s = 14

Test statistic = (xbar - μ) ÷ (s/√(n))

Test statistic = (830 - 840) ÷ (14/7)

Test statistic = - 10 / 2

Test statistic = - 5

The Pvalue ;

Pvalue = P(Z < - 5) = 0 (Z probability calculator)

The Pvalue = 0

The table of values below represents a linear relationship.

Yuki888 [10]

Given:

The table of values.

To find:

The slope and y-intercept for this line.

Solution:

From the given table, we have three (-4,6), (0,3), (4,0).

We need to find the slope and y-intercept for this line.

Consider any two points from the given points.

Consider the line passes through the points (0,3) and (4,0). So, the slope of the line is:

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

$m=\dfrac{0-3}{4-0}$

$m=\dfrac{-3}{4}$

The line passes through the point (0,3). Here the x-coordinate is 0. So, the y-intercept is 3.

Therefore, the slope of the line is $\dfrac{-3}{4}$ and the y-intercept of the line is 3.

Ad libitum [116K]

Answer:

12.9

Step-by-step explanation:

AB = $\sqrt{2^{2}+3^{2} }$ = $\sqrt{13}$

BC = $\sqrt{2^{2}+2^{2} }$ = $2\sqrt{2}$

CD = $\sqrt{1^{2}+2^{2} }$ = $\sqrt{5}$

DE = 3

EA = $\sqrt{1^{2} + 2^{2} }$ = $\sqrt{5}$

The sum of all of these (in decimal form) is (approx.) 12.9

the length of a rectangle is 7 cm less than its width what are the dimensions of the rectangle if its area is 120 cm²

STatiana [176]

Answer: The length of the rectangle is 8cm while the width is 15cm.

Step-by-step explanation: The length of the rectangle has been described as 7cm less than it’s width. This means if the width is given as W, then the length would be 7 less than W, that is, length would be W - 7. Also the area has been given as 120. With this bit of information we can now express the area as follows;

Area of a rectangle = L x W

Where area is 120, length is W - 7 and width is W.

120 = (W-7) x W

120 = W^2 - 7W

We rearrange all terms on one side of the equation and we now have

W^2 - 7W - 120 = 0

What we now have is a quadratic equation, and by factorizing we now have

(W + 8) (W - 15) = 0

(W + 8) = 0 and (W - 15) = 0

Hence, either W + 8 = 0 and W = -8

OR W - 15 = 0 and W = 15.

We know that the dimensions of the rectangle cannot be a negative number, so we choose W = 15.

Having calculated that, if the length is given as W - 7, then the length is

L = 15- 7

L = 8

Therefore, the length is 8cm and the width is 15cm.
