Step-by-step explanation:

The given scatter plot has a positive correlation.

Given that, the scatter plot shows the number of hours worked and money spent on entertainment by every 24 students.

A scatter plot is a means to represent data in a graphical format. A simple scatter plot makes use of the coordinate axes to plot the points, based on their values. The following scatter plot excel data for age (of the child in years) and height (of the child in feet) can be represented as a scatter plot.

A positive correlation—when the correlation coefficient is greater than 0 signifies that both variables move in the same direction.

The blanks for the given questions are filled below:

a) increase

b) strong positive

c) $22.50

Therefore, the given scatter plot has a positive correlation.

Answer:

$10.71

Step-by-step explanation:

[tex]\frac{3.75}{y} =\frac{35}{100}[/tex]

y × 35 = 3.75 × 100

35y = 375

35y ÷ 35 = 375 ÷ 35

[tex]y=10\frac{5}{7}[/tex]

y = 10.7142857143

10.7142857143 round to 10.71

Step-by-step explanation:

Answer:

(2,14)

Step-by-step explanation:

Since y=5x+4, you can plug that into the other y in the other equation which would give you x+12=5x+4

Now subtract 12 from both sides

x=5x-8

Subtract 5x from both sides

-4x=-8

Now you divide them both by -4 which gives you x=2

Now plug x in to any of the equations

y=5(2)+4

y=10+4

y=14

Your final answer is (2,14)

The answer is "[tex]0.02235 \ and \ 0.02501[/tex]".

Step-by-step explanation:

Given:

[tex]x= 1184\\\\n = 50000\\\\c = 95\% = 0.95[/tex]

The sample proportion is computed by subtracting that sample size by both the successes:

[tex]\hat{p}=\frac{x}{n} =\frac{1184}{50000}= 0.02368[/tex]

Determine [tex]z_{\frac{\alpha}{2}} = Z_{0.025}[/tex] using table Z in Table Z for trust level [tex]1 -\alpha = 0.95[/tex]

add using appendix F ((0.025) inside the table, therefore the z-score is the found z-score with negative sign):

So, the boundaries of the confidence interval:

[tex]\to \hat{p}-z_{\frac{\alpha}{2}} \cdot \sqrt{\frac{\hat{p} (1-\hat{p})}{n}} = 0.02368 - 1.96 \cdot \sqrt{\frac{0.02368(1-0.02368)}{50000}}\approx 0.02235 \\\\\to \hat{p}-z_{\frac{\alpha}{2}} \cdot \sqrt{\frac{\hat{p} (1-\hat{p})}{n}} = 0.02368 + 1.96 \cdot \sqrt{\frac{0.02368(1-0.02368)}{50000}}\approx 0.02501\\\\[/tex]

Answer:

see explanation

Step-by-step explanation:

so, when a=-3, c is -20. now, to find b when a is -3, plug a (which is -3) into the equation b=4a-5 to get b=-17. so b=-17, c=-20. b is obviously larger (remember the negative sign)

when c is 21, a is 5. plug numbers in to get b=15.

when a is 6, there is no clear value for c, so i'd guess undefined. b however is 19

we can plot the line and the points, for problem 4 and all points above the line means that c is greater than b, and when below it's less than. doing this we get when a is 12, when a is 0, and when a is 5. hope this was clear

Answer:

x = 21.06 units

Step-by-step explanation:

Given that,

Base, b = 20

Height, h = x

Angle = 36

We need to find the value of x. Trigonometric formulas are used to solve such problems such that,

[tex]\tan(36)=\dfrac{x}{29}\\\\x=29\times \tan(36)\\\\x=21.06[/tex]

So, the value of x is equal to 21.06 units.

Answer:

[tex]y\leq -6[/tex]

Step-by-step explanation:

[tex]\frac{1}{2}y \leq -3[/tex]

Our inequality requires first to solve for y.

To solve for a variable, we must isolate it.

In this case, first, we can multiple by the inverse of the fraction which is 2.

[tex]\frac{1}{2}y\leq -3\\[/tex]

[tex]2(\frac{1}{2}y)\leq -3(2) \\[/tex]

1*y=y and -3*2=-6

So our inequality stands like this -

[tex]y\leq -6[/tex]

Answer:

C

Step-by-step explanation:

30 x 60 x 70 = 126,000

90 x 60 x 30 = 288,000

288,000 + 126,000 = 288,000cm^3

Answer: 288,000 [tex]cm^{3}[/tex]

Step-by-step explanation:

first, break down the shape thingy into two different shapes. there's more than one way to do it, but i'll be cutting the shape horizontally at the corner of the L shape (where the 40 cm and 90 cm lines connect)

small prism dimensions: 60 x 30 x 40 = 72,000

large prism dimensions: (30+90) x (70-40) x 60 / 120 x 30 x 60 = 216,000

add them to get 288,000 [tex]cm^{3}[/tex]
