Answer:
k = 5
Step-by-step explanation:
First, add 3 to both sides;
[tex]7k = 35[/tex]
Divide by 7:
[tex]\frac{7}{7}k = \frac{35}{7}\\k = 5[/tex]
Now, let's check our answer:
[tex]7(5) - 3 = 32\\35 - 3 = 32\\32 = 32[/tex]

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
Samantha invested $660 into an account that pays 3.5% interest compounded annually . Samantha did not make any additional deposits or withdrawals .
What is the total amount of interest paid by this investment at the end of five years?
A- $115.50
B-$783.87
C-$123.87
$2,755.50
The amount of money after five years will be $783.87. Then the correct option is B.
What is compound interest?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.

Kevin’s rate of change is _______. Dylan’s because Kevin sells_______ cars per year employed and Dylan sells ________ cars per year employed.
Answer:
I been trying to look for that answer for so long but can we help each other at least
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.

Jamal ran a distance of 360 feet. Lonnie ran a distance of 30 yards. What is the ratio of the distance Jamal ran to the distance Lonnie ran?
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

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]

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%

What is the angle measure of angle ABC?
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°

what’s the slope?
a line has the given equation y=-3x-10
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)

10) A survey of business students who had taken the Graduate Management Admission Test (GMAT) indicated that students who have spent at least five hours studying GMAT review guides have a probability of 0.85 of scoring above 400. Students who do not spend at least five hours reviewing have a probability of 0.65 of scoring above 400. It has been determined that 70% of the business students spent at least five hours reviewing for the test. a. Find the probability of scoring above 400. b. Find the probability that given a student scored above 400, he/she spent at least five hours reviewing for the test.
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
