If the vertical length is 10 , what is the horizontal length?

Answer:

x=0

Step-by-step explanation:

expand x-(3-2x)-(4-5x)=-7

x-3+2x-4+5x=-7

8x-7=-7

8x-7+7=0

8x=0

x=0

Answer:

Well you can subtract 12 from 50 make sure the larger number Is in front an the smaller number then you would get 38 so he would have to make more than 38 tracks to make a a profit

Answer:

427,786 Flowers

Step-by-step explanation:

135, 643 + 9,756 = 145,399

145, 399 + 1,345 = 146,744

135,643 + 145,399 = 281,042 + 146,744 = 427,786

Answer:

a) drinking caffeinated coffee

b) hyperactivity

c) experimental study

d) Non-Probability Sampling Method

Explanation:

a) An independent variable refers to the object(s) or variable that is been measured which is not affected or changed by other variables. Rather, the independent variable affects or changes other variables. That is why drinking caffeinated coffee falls under the independent variable.

b) The dependent variable on other hand is a variable that can be affected or changed by the independent variable. That is why hyperactivity falls under the dependent variable.

c) Noteworthy is the fact that in an experimental study a researcher usually alters the level of the independent variable [the caffeinated coffee]. This is evident in this case because we are told, "One group received regular coffee and the other received decaffeinated coffee."

d) The kind of sampling method used is the Non-Probability Sampling Method because they [the students] which formed the population were not randomly selected, but "intentionally balanced" into groups by the student’s year, major, and gender.

Answer:

A: 2/10

Step-by-step explanation:

She's pouring the 2 quarts into 10 cups, therefore if you drew it out, the amount each cup would have 1/5(or 2/10) of the quart.

Answer:

0.3

Step-by-step explanation:

1.9r + 0.1r = 0.6

Add like terms on the left side.

2r = 0.6

Divide both sides by 2.

r = 0.3

Answer:

3.333 continued

Step-by-step explanation:

Add 1.9r and .1r because they are like terms and you get 2r

Divide 2/.6

r = 3.3333

Answer:

2 ( plot the answer on 2)

Step-by-step explanation:

We do the reciprocal of 3/10 because we are dividing fraction. Which would be 10/3. Change the sign to multiplication because we are dividing fractions. And multiply regularly. SO it would be 3/5 times 10/3 = 2

Answer:

-38

Step-by-step explanation:

Answer:

(0, 7)

Step-by-step explanation:

Given:

J(-4, 11)

K(8, -1)

JP:JK = 1/3

Required:

Coordinates of P

SOLUTION:

Use the formula, [tex] (x, y) = (x_1 + k(x_2 - x_1), y_1 + k(y_2 - y_1)) [/tex] to find the coordinates of point P, that partition the segment JK into the ratio 1/3.

Let,

[tex] J(-4, 11) = (x_1, y_1) [/tex]

[tex] K(8, -1) = (x_2, y_2) [/tex]

[tex] k = \frac{1}{3} [/tex]

Thus, plug in the values as follows:

[tex] P(x, y) = (-4 + \frac{1}{3}(8 -(-4)), 11 + \frac{1}{3}(-1 - 11) [/tex]

[tex] P(x, y) = (-4 + \frac{1}{3}(12), 11 + \frac{1}{3}(-12) [/tex]

[tex] P(x, y) = (-4 + \frac{12}{3}, 11 + \frac{-12}{3}) [/tex]

[tex] P(x, y) = (-4 + 4, 11 + (-4) [/tex]

[tex] P(x, y) = (0, 7) [/tex]

The coordinates of point P, are (0, 7)

Answer:

Step-by-step explanation:

Given that:

The population proportion = 8.1% = 0.081

Sample size = 1000

The sample proportion [tex]\hat p[/tex] = 6.5%  = 0.065

The null and the alternative hypothesis for these studies can be computed as:

[tex]\mathbf{H_o : p = 0.081} \\ \\ \mathbf{H_1 : p \neq 0.081}[/tex]

Since [tex]H_1[/tex] is not equal to the population proportion; then this is a two-tailed test.

The level of significance is given as 5% = 0.05

The standard error [tex]\sigma_p[/tex] of the sample proportion [tex]\hat p[/tex] can be computed as:

[tex]\sigma_p = \sqrt{\dfrac{p(1-p)}{n} }[/tex]

[tex]\sigma_p = \sqrt{\dfrac{0.081(1-0.081)}{1000} }[/tex]

[tex]\sigma_p = \sqrt{\dfrac{0.081(0.919)}{1000} }[/tex]

[tex]\sigma_p = 0.0086[/tex]

The z score test statistic is calculated as:

[tex]z =\dfrac{\hat p - p}{\sigma_p}[/tex]

[tex]z =\dfrac{0.065- 0.081}{0.0086}[/tex]

z = −1.860

For a two-tailed test, the p-value = [tex]2 \times P(Z < -|z|)[/tex]

[tex]p-value = 2 \times P(Z < - 1.86)[/tex]

p-value = 2 × 0.0314

p-value = 0.0628

Rejection Criteria: To reject [tex]H_o[/tex] ; if the p-value is less than the level of significance ∝

The decision rule: We failed to reject the null hypothesis since the p-value is greater than the level of significance ∝.

Thus, there is insufficient evidence to conclude that p is not equal to 0.081

Answer:

Step-by-step explanation:

JK + KL = JL

(4x + 3) + (9x + 5) = 47

4x + 9x = 47 - 3 - 5

13x = 39

x = 39 / 13

x = 3

Answer:

see below

Step-by-step explanation:

z1 = sqrt(3) -i

z2 = -i

z1+z2 = sqrt(3) -i  + -i = sqrt(3) -2i

z1-z2 = sqrt(3) -i  - -i = sqrt(3)  +-i +i = sqrt(3)

z1*z2 = sqrt(3) -i  * -i = sqrt(3)*-i -i*-i = -sqrt(3)i + i^2 = -sqrt(3)i -1

z1/z2 = sqrt(3) -i  / -i = sqrt(3)/-i - i/-i = sqrt(3) *i/-i*i +1 = sqrt(3)i/-i^2 +1

                                     = sqrt(3) i +1

Step-by-step explanation:

S = ∫ 2π y ds

ds = √(1 + (dx/dy)²) dy

ds = √(1 + (8y)²) dy

ds = √(1 + 64y²) dy

S = ∫₁² 2π y √(1 + 64y²) dy

S = π/64 ∫₁² 128y √(1 + 64y²) dy

S = π/64 [⅔ (1 + 64y²)^(³/₂)] |₁²

S = π/96 (1 + 64y²)^(³/₂) |₁²

S = π/96 (1 + 256)^(³/₂) − π/96 (1 + 64)^(³/₂)

S = π/96 (257√257) − π/96 (65√65)

S = π/96 (257√257 − 65√65)
