Answer:
♡ hi there, madi here! ♡
hope your having a great day.
I did the math so here's your answer.
2x−3)(x−3)=0
If any individual factor on the left side of the equation is equal to 0, the entire expression will be equal to 0.
2x-3=0. x-3=0
Set the first factor equal to 0 and solve.
x=3/2
Set the next factor equal to 0 and solve.
x=3
Therefore, the final solution is all the values that make (2x-3) (x-3)=0 true. x=3/2,3♡

Find the rate of change
Answer:
The rate of change of function is: 2
Step-by-step explanation:
Using the given table we have to exclude two pairs of input and output.
The rate of change or slope of function is given as:
[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]
We take first two pairs of input/output from the table
(x1,y1) = (1,11)
(x2,y2) = (2,13)
Putting the values
[tex]m = \frac{13-11}{2-1}\\m =\frac{2}{1}\\m = 2[/tex]
Hence,
The rate of change of function is: 2

D) 1.2, 1.48, 2.01, 1.234, 1.237
Answer:
C
Step-by-step explanation:
The highest number here is 2.01, so we start by looking for an answer that begins with 2.01. Then we compare 1.48, 1.237,1.234, and 1.2. Look into the tenths place to find that 1.48 has a larger tenths place than any other number. continue this cycle to have the full correct order.
An insurance company has written 100 policies for $75,000, 500 policies for $25,000, and 1000 policies for $10,000 for people of age 20. If experience shows that the probability that a person will die at age 20 is 0.0015, how much can the company expect to pay out during the year the policies were written? The company can expect to pay out _____ $ over the year after the policies were written.
Answer:
The company can expect to pay out $45,000 over the year after the policies were written.
Step-by-step explanation:
This can be determined as follows:
The probability that a person will die at age 20 = 0.0015
Revenue from 100 policies = 100 * $75,000 = $7,500,000
Revenue from 500 policies = 500 * $25,000 = $12,500,000
Revenue from 1000 policies = 1000 * $10,000 = $10,000,000
Total revenue from all policies = Revenue from 100 policies + Revenue from 500 policies + Revenue from 1000 policies = $7,500,000 + $12,500,000 + $10,000,000 = $30,000,000
Expected amount to pay out during the year the policies were written = Total revenue from all policies * The probability that a person will die at age 20 = $30,000,000 * 0.0015 = $45,000
Therefore, the company can expect to pay out $45,000 over the year after the policies were written.

Solve: x=4+(4x-4)1/2
Answer:
x = 10
Step-by-step explanation:
x = 4 + (4x-4) ^ (1/2)
First, we rewrite the expression:
x = 4 + (4x-4) ^ (1/2)
x = 2 (2+ (x-1) ^ (1/2))
x = 4 + 2 (x-1) ^ (1/2)
From here we get a solution for x = 10
To check it we substitute x = 10 in the expression:
10 = 4 + 2 (10-1) ^ (1/2)
10 = 4 + 2 (9) ^ (1/2)
10 = 4 + 2 (3)
10 = 4 + 6
10 = 10

The time to failure (in hours) of fans in a personal computer can be modeled by an exponential distribution with l=0.0003
a. What proportion of the fans will last at least 10,000 hours?
b. What proportion of the fans will last at most 7000 hours?
Answer: 0.0497870 ; 0.87754
Step-by-step explanation:
Given that :
λ = 0.0003
Defining a continuous distribution function :
F(x) = 1 - e^-λx = 1 - e^-0.0003x ; x ≥ 0
a. What proportion of the fans will last at least 10,000 hours?
P(x ≥ 10000) = e^-0.0003(10000) = 0.0497870
b. What proportion of the fans will last at most 7000 hours?
P(x ≥ 7000) = 1 - p(x ≤ 7000) = 1 - e^-0.0003(7000)
1 - 0.12245642825 = 0.87754
A nursery has $55,000 of inventory in dogwood trees and red maple trees. The profit on a dogwood tree is 29% and the profit on a red maple tree is 18%. The profit for the entire stock is 20%. How much was invested in each type of tree?
Answer:
On dogwood $45,000 was invested
On red maple tree , $10,000 would be invested
Step-by-step explanation:
Let the amount invested on dogwood tree be d and the amount invested on red maple be r
Total is 55,000
Thus;
d + r = 55,000 ••••••(i)
Total profit is;
20/100 * 55,000 = 11,000
Profit on dogwood is;
29/100 * d = 0.29d
Profit on red maple is;
18/100 * r = 0.18r
Both equals 11,000
0.29d + 0.18r = 11,000 •••••••(ii)
From equation i, d = 55,000 - r
substitute into ii
0.29(55,000-r) + 0.18r = 11,000
15950- 0.29r + 0.18r = 11,000
4950 = 0.11r
r = 4950/0.11
r = 45,000
d = 55,000 - r
d = 55,000 - 45,000
d = 10,000

Charlene and Danielle share some money in ratio 2:3
Danielle gets £25 more than Charlene.
How much does each girl receive?
Answer:
Charlene got £50
Danielle got £75
Step-by-step explanation:
Let Charlene get x
this means that Danielle will get x + 25
The ratio is thus;
x/x + 25 = 2/3
3x = 2(x + 25)
3x = 2x + 50
3x-2x = 50
x = £50
Charlene got this
The amount Danielle got will be
50 + 25 = £75

Answer:
Angle 8
Step-by-step explanation:
Angle 8 is the corresponding angle to angle 4. Corresponding angles are angles that are in the same relative position at each intersection. Since the lines are parallel they are also congruent. If you look at the lines both angle 8 and 4 are on the bottom right side of the intersection, therefore they are corresponding angles.
what is the answer 42 ounces to 5 pounds in simplest form
42 ounces is equivalent to 2.625 pounds.
To convert 42 ounces to pounds, we divide by the conversion factor of 16 ounces per pound, since there are 16 ounces in a pound:
= 42 ounces / 16 ounces per pound
= 2.625 pounds
Now, to express 2.625 pounds in simplest form.
Since it is in decimal form, so we don't need to simplify it further.
Therefore, 42 ounces is equivalent to 2.625 pounds.

You have one type of nut that sells for $6.50/lb and another type of nut that sells for $8.60/1b. You
would like to have 14.7 lbs of a nut mixture that sells for $7.10/lb. How much of each nut will you
need to obtain the desired mixture?
You will need
____lbs of the cheaper nut
and
____lbs of the expensive nut.
Answer:
You buy 10.5 pounds of the $6.50/lb nuts and 4.2 pounds of the $8.60/lb nuts.
Step-by-step explanation:
Let x be the number of pounds of the cheaper nut.
6.5x + 8.6(14.7-x) = 7.1*14.7
6.5x + 126.42 - 8.6x = 104.37
2.1x = 22.05

Iris wants to buy two necklaces, one for her sister and one for herself. The necklace for her sister costs $42.00, and the necklace for herself costs $28.00. The sales tax on the purchases is 8%. Find the total cost of Iris’s purchases, including sales tax. If necessary, round your answer to the nearest cent.
Answer:
$75.60
Step-by-step explanation:
First, find the total cost without tax:
42 + 28
= 70
Then, to find the price with sales tax, multiply this by 1.08:
70(1.08)
= 75.6
So, the total cost of her purchases was $75.60

Jamie used a microscope to measure the diameter of a hair. She found that the
diameter of the hair was 0.000072 meter. How is this number written in scientific
notation?
A. 7.2x10.5
B. 7.2 x 106
C.7.2 x 105
D.7.2 x 10
Type Your
Answer:
7.2 *10⁻⁵
Step-by-step explanation:
Given the diameter of the hair expressed as 0.000072, we are to express it in scientific notation.
The standard form of scientific notation is expressed as;
A * 10ⁿ
A is a value from 1 to 9
n is any integer.
Rewriting 0.000072 in this form, we will need to shift the decimal point to the front 5 times to have;
0.000072 = 7.2 *10⁻⁵ where;
A = 7.2 and n = -5
Note that the power is a negative value since the value is less than 1.
