Answer:

Number of students = 441 Students

Step-by-step explanation:

Given:

Percent of women = 40%

Percent of women = 35.5%

Total number of people = 1,800

Find:

Number of students

Computation:

Percent of student = 100% - 35.5% - 40%

Percent of student = 24.5%

Number of students = 1,800 x Percent of student

Number of students = 1,800 x 24.5%

Number of students = 441 Students

Answer:

x=3, y=13. (3, 13).

Step-by-step explanation:

7x-8=5x-2

7x-5x-8=-2

2x-8=-2

2x=-2+8

2x=6

x=6/2=3

y=5(3)-2=15-2=13

Answer:

given y=7x-8 i

y=5x-2 ii

Step-by-step explanation:

equating equation i and ii which is i=ii

7x-8=5x-2

7x-5x= -2+8

2x=6

x=6÷2

x=3

now

putting the value of xbin equation i

y=7x-8

y=7×3-8

y=21-8

y=13

hence the value of x and y is 3 and 13 respectively

Answer:

a=54

Step-by-step explanation:

EASY

look triangles are 180 degrees

means all 3 sides add to 180

look at 2a and the missing angle they add up to 180

180-(a+10)-44

missing angle is

−a+126

exteriro plus interior angles add up to 180

-a+126+2a=180

solve and simplify

a=54

Answer:

0.79 ; 0.753

Step-by-step explanation:

Given that:

Students who have spent at least five hours studying GMAT review guides have a probability of 0.85 of scoring above 400 :

≥ 5 hours review = 0.85

Students who do not spend at least five hours reviewing have a probability of 0.65 of scoring above 400

< 5 hours = 0.65

70% (0.7) of business students spend atleast 5 hours review time

A.) probability of scoring above 400

(Proportion who spend atleast 5 hours review time * 0.85) + (Proportion who do not spend atleast 5 hours * 0.65)

Proportion who do not spend atleast 5 hours = (1 - proportion who spend atleast 5 hours) = 1 - 0.7 = 0.3

Hence,

P(scoring above 400) = (0.7 * 0.85) + (0.3 * 0.65) = 0.595 + 0.195

= 0.79

B.) probability that given a student scored above 400, he/she spent at least five hours reviewing for the test.

P(spent ≥5 hours review | score above 400) :

P(spent ≥5 hours review) / P(score > 400)

(0.7 * 0.85) / 0.79

0.595 / 0.79

= 0.753

Answer:

92°

Step-by-step explanation:

First, find the value of x.

3x + 23 = 4x (corresponding angles are congruent)

Subtract 3x from each side

23 = 4x - 3x

23 = x

x = 23

Angle ABC = 4x

Plug in the value of x

Angle ABC = 4(23)

Angle ABC = 92°

The ratio of the distance Jamal ran to the distance Lonnie ran is 4:1.

Note that 1 yard = 3 feet

Since Jamal ran a distance of 360 feet, this will be converted to yard and this will be: = 360/3 = 120 yards

Lonnie ran a distance of 30 yards.

Then the ratio of the distance that Jamal ran to the distance Lonnie ran all be: = 120/30 = 4/1 = 4:1

The ratio of the distance is 4:1

Answer:

Step-by-step explanation:

We have  Kevin's sales equation is

[tex]S=60n-5[/tex]

Step 1

Find out Dylan's sales equation

Find the slope

We need two points

We take

[tex](2,104)[/tex] And [tex](6,324)[/tex]

[tex]m=(324-104)/(6-2)[/tex]

[tex]m=\frac{220}{4} \\m=55[/tex]

Find the equation in slope intercept form

[tex]s=mn+b[/tex]

We have

[tex]m=55[/tex]

point [tex](2,104)[/tex]

Substitute and solve for b

[tex]104=55(2)+b\\[/tex]

[tex]b=104-110\\b=-6\\[/tex]

So

[tex]S=55n-6\\[/tex]

Therefore

Kevin's rate of change is 60

Dylan's rate of change is 55

Compare

Kevin's rate of change is greater than Dylan's rate of change because Kevin's sell 60 cars per year and Dylan's sells 55 cars per year.

The amount of money after five years will be $783.87. Then the correct option is B.

A loan or deposit's interest is computed using the starting principle and the interest payments from the ago decade as compound interest.

We know that the compound interest is given as

[tex]\rm A = P \left (1 + \dfrac{r}{n} \right ) ^{nt}[/tex]

Where A is the amount, P is the initial amount, r is the rate of interest, and t is the number of years.

Samantha put $660 into a record that pays 3.5% interest accumulated every year. Samantha put aside no extra installments or withdrawals. And for yearly, the value of n will be one. Then the equation is given as,

[tex]\rm A = 660\times (1 + 0.035)^t[/tex]

The total amount of interest paid by this investment at the end of five years will be given as,

A = 660 x (1.035)⁵

A = $660 x 1.1876

A = $783.87

The amount of money after five years will be $783.87. Then the correct option is B.

Answer: slope= -6.0/2.0= -3.0

Step-by-step explanation:

Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is -10.000 and for x=2.000, the value of y is -16.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of -16.000 - (-10.000) = -6.000 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

x-intercept = -10/3 = -3.33333

 y-intercept = -10/1 = -10.00000

We need to find the regression equation y = bx + a

Where [tex]b=\frac{SP}{SS_x} \:and\: a=M_y-bM_x[/tex]

Sum of all values of x = 245

Sum of all values of y = 30

Now, calculating mean using formula: [tex]Mean=\frac{Sum\:of\:all|\:values}{Number\:of\:values}[/tex]

Mean of x (Mₓ) = 35

Mean of y ([tex]M_y[/tex]) = 4.28

Sum of squares (SSₓ) = 700

Sum of products (SP) = -190

Now, finding b:

[tex]b=\frac{SP}{SS_x} \\b=\frac{-190}{700}\\b=-0.271[/tex]

Now, finding a:

[tex]a=M_y-bM_x\\a=4.28-(-0.271*35)\\a=13.786[/tex]

So, the required equation is:

[tex]y=\mathbf{-0.271}x+\mathbf{13.876}[/tex]
