three shapes. three areas to find. three areas to add together to find the whole area. gotcha.

Step-by-step explanation:

length is 7 cm and width is 4 cm, so the area is 28 square cm

width is 4 cm and length is 10 cm, so the area is 40 square cm

Because the weird shape's bottom length was 13 cm. There are 3 cm and 7 cm on the top length(s) of the weird shape, next to each other. Looking at the dash lines, when adding 3 cm and 7 cm together, the larger rectangle's length is 10 cm.

base is 3 cm and height is 8 cm, so the area is (3x8)/2 = 24/2 = 12 square cm

With knowledge from figuring out the larger rectangle's length being 10 cm and the weird shape's bottom length being 13 cm, we know the right triangle's base is 3 cm. (13 cm - 10 cm = 3 cm for the base of the right triangle).

Due to adding 4 cm and 4 cm of weird shape's width, which is also a right triangle's height.

28 + 40 + 12

= 80 square cm (ANSWER)

Answer:

E) The sample size is n = 1,000, and 50 percent of all students use the vending machines.

Step-by-step explanation:

CollegeBoard

For the following  situations the power of the test be highest is, The sample size is n = 1000, and 55 percent of all students actually use the vending machines. So Option C is correct

The power of the hypothesis test depends on three factors.

1. Sample size (n). Other things being equal, the greater the sample size, the greater the power of the test.

2. Significance level (α) : which is constant in this question.

(3) The "true" value of the parameter being tested. The greater the difference between the "true" value of a parameter and the value specified in the null hypothesis, the greater the power of the test.

Given that,

A random sample of n students will be selected

A large-sample test for proportions at the significance level of α = 0.05

The null hypothesis that the proportion of all students who would use the vending machines is 20%

Power of test would be highest,

For the largest sample size

Option C,  has largest sample size

difference = true value - value specified in null hypothesis

= 55 - 20

= 35

both the conditions are satisfied for being a highest power of the test

To find:

The correct application of the quadratic formula.

Solution:

If a quadratic equation is [tex]ax^2+bx+c=0[/tex], then the quadratic formula is

[tex]x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]

We have,

[tex]y=6x^2-9x+22[/tex]

Putting [tex]y=0[/tex], we get

[tex]6x^2-9x+22=0[/tex]

Here, [tex]a=6,b=-9,c=22[/tex]. Using the quadratic formula, we get

[tex]x=\dfrac{-(-9)\pm \sqrt{(-9)^2-4(6)(22)}}{2(6)}[/tex]

The correct application of the quadratic formula is [tex]x=\dfrac{-(-9)\pm \sqrt{(-9)^2-4(6)(22)}}{2(6)}[/tex].

Answer:

y = 5x-5

Step-by-step explanation:

First find the slope

m = ( y2-y1)/(x2-x1)

   = ( 10-5)/(3-2)

   = 5/1

  =5

Using slope intercept form

y = mx+b

y = 5x+b

Substituting a point into the equation

5 = 5*2+b

5 = 10+b

Solving for b

5-10 = b

-5 =b

y = 5x-5

Answer:

f(x) = 20,000(0.85)^x

Step-by-step explanation:

Given data

Cost of car P= $20,000

rate of depreciation r= 15%

Let us apply the depreciation formula

f(x) = P(1-r)^t

substitute

f(x) = 20000(1-0.15)^x

f(x) = 20000(0.85)^x

Therefore the correct expression is option 1

f(x) = 20,000(0.85)^x

420 is the correct answer

Answer:

420

Step-by-step explanation:

Answer:

129.8 mmHg

42 years

Step-by-step explanation:

Given the relation :

P = 0.006 y² − 0.02 y + 121

Systolic blood pressure, P

Age, y

A.)

Find P when age y = 40

P = 0.006(40)² − 0.02(40) + 121

P = 9.6 - 0.8 + 121

P = 129.8 mmHg

B)

P = 130.74 mmHg

y =?

130.74 = 0.006y² − 0.02y + 121

130.74 - 121 = 0.006y² − 0.02y

9.74 = 0.006y² − 0.02y

0.006y² − 0.02y - 9.74 = 0

Using a quadratic equation solver :

The roots are 41.99 and - 38.66

Age cannot be negative ;

Hence age = 41.99 = 42 years

Answer:

(a) See attachment for table

(b) [tex]Atmost\ 6 = 21.667\%[/tex]

(c) [tex]Less\ than\ 6 = 21.667\%[/tex]

(d) [tex]At\ least\ 6 = 78.333\%[/tex]

Step-by-step explanation:

Given

The data (in the question)

Solving (a): Frequency and Relative frequencies of each data

The range of the data is 0 to 8. So the frequency of each is the number of times each of 0 - 8 occurs.

This is tabulated below:

[tex]\begin{array}{ccc}x & {Frequency} & {Relative\ Frequency} & {0} & {7} & {11.667\%} &{1}& {13} & {21.667\%} & {2} & {13} & {21.667\%} & {3} & {14} &{23.333\%} & {4} & {5} & {8.333\%} & {5} &{3} &{5.000\%} &{6} &{2} & {3.333\%} & {7} & {2} & {3.333\%} & {8} & {1} & {1.667\%} \ \end{array}[/tex]

[tex]Total\ \ \ 60[/tex]

The relative frequency is calculated as:

[tex]Relative\ Frequency = \frac{Frequency}{Total\ Frequency} * 100\%[/tex]

For instance: When x = 0:

[tex]Relative\ Frequency = \frac{7}{60} * 100\%[/tex]

[tex]Relative\ Frequency = \frac{700}{60} * \%[/tex]

[tex]Relative\ Frequency = 11.667 \%[/tex]

Solving (b): Proportion that have at most 6.

Here, we consider frequencies of 0 to 6.

This is represented as thus:

[tex]\begin{array}{ccc}x & {Frequency} & {Relative\ Frequency} & {4} & {5} & {8.333\%} & {5} &{3} &{5.000\%} &{6} &{2} & {3.333\%} & {7} & {2} & {3.333\%} & {8} & {1} & {1.667\%} \ \end{array}[/tex]

Add up the relative frequencies to get the proportion

[tex]Atmost\ 6 = 8.333\% + 5.000\% + 3.333\% + 3.333\% + 1.667\%[/tex]

[tex]Atmost\ 6 = 21.667\%[/tex]

Solving (c): Proportion that have at fewer than 6.

Here, we consider frequencies of 0 to 5.

This is represented as thus:

[tex]\begin{array}{ccc}x & {Frequency} & {Relative\ Frequency} & {4} & {5} & {8.333\%} & {5} &{3} &{5.000\%} &{6} &{2} & {3.333\%} & {7} & {2} & {3.333\%} & {8} & {1} & {1.667\%} \ \end{array}[/tex]

Add up the relative frequencies to get the proportion

[tex]Less\ than\ 6 = 8.333\% + 5.000\% + 3.333\% + 3.333\% + 1.667\%[/tex]

[tex]Less\ than\ 6 = 21.667\%[/tex]

Solving (d): Proportion that have at least 6.

Here, we make use of the complement rule:

[tex]At\ least\ 6 = 100\% - Less\ than\ 6[/tex]

[tex]At\ least\ 6 = 100\% - 21.667\%[/tex]

[tex]At\ least\ 6 = 78.333\%[/tex]
