Answer:
Perimeter: 17 inches
Area: 8 square inches
Step-by-step explanation:
The ratio of perimeters is the same as the similarity ratio.
JKLM perimeter / ABCD perimeter = P/68 = 1/4
Multiplying by 68, we get ...
P = 68/4 = 17 . . . . inches
__
The ratio of areas is the square of the similarity ratio.
JKLM area / ABCD area = A/128 = (1/4)^2
Multiplying by 128, we get ...
A = 128/16 = 8 . . . . square inches
__
Perimeter = 17 inches
Area = 8 square inches
Mai solved the equation below incorrectly. Identify Mai's error and then solve the equation correctly.
X-9) = {(x + 18)
3x - 3= kx +9

X-3=9

41
-x = 12
X = 48
What was Mai's error?
Answer: Please see explanation column for answer.
x= -36
Step-by-step explanation:
Step 1
from the attachment, Mai's solving is given as
1/3 (1/2x- 9) = 1/2 (x+18)
1/6x-3= 1/2x+9
1/4x-3=9
1/4x=12
x=48
Mai's error started when he subtracted wrongly 1/2 x from 1/6x which gave him 1/4 x instead of - 1/3 x.
Solving correctly, we have that
1/3(1/2x-9) = 1/2(x+18)
1/6x -3= 1/2x+ 9
taking like terms to like terms
1/6x-1/2x= 9+3
(1-3)/6x= 12
-2/6x= 12
-1/3x= 12
multiplying both sides by -3
-1/3x X -3 = 12 X -3
x= -36
A large company states in its promotional literature that 74% of its employees have college degrees. Assume this claim is true. If 3 employees are selected at random from this company, what is the probability that at least 1 of the selected employees will not have a college degree?
A. 0.0176
B. 0.4052
C. 0.5948
D. 0.9284
Answer:it is 0.5948
Step-by-step explanation:c
The probability that at least 1 of the selected employees will not have a college degree is 0.594776.
What is Binomial distribution?A common discrete distribution is used in statistics, as opposed to a continuous distribution is called a Binomial distribution. It is given by the formula,
[tex]P(x) = ^nC_x p^xq^{(n-x)}[/tex]
Where,
x is the number of successes needed,n is the number of trials or sample size,p is the probability of a single success, andq is the probability of a single failure.Given that 74% of the employees have degrees, therefore, 26% of the employees have no degree.
Now, since we want at least any one of the three people selected to have a degree. Therefore, the probability of everyone having a degree can be written as,
Probability that at least any one of the three people selected to have a degree = 1 - Probability of everyone having a degree
Now, using the binomial distribution we can write,
[tex]\text{Probability} = 1 - [^3C_0\cdot(0.26)^0 \cdot (0.74)^{(3-0)}]\\\\\text{Probability} = 1 - 0.405224 = 0.594776[/tex]
Hence, the probability that at least 1 of the selected employees will not have a college degree is 0.594776.

6x-y=1 convert the standard form to a slope intercept.
Answer:
y= 6x-1
Step-by-step explanation:
6x-y=1
-y= -6x+1 (move x over to the right side)
y= 6x-1 (divide both sides by -1)
The store plans to purchase the uniforms and hand out 5 uniforms to every employee, one for each day of the week uniforms come in packs of 8, and the store plans to purchase 56 packs of uniforms. How many employees can store give uniforms to? Will the store have any uniforms left over?
Answer:
89 employees
3 uniforms left
Step-by-step explanation:
Number of Uniforms per employee = 5
Uniform per pack = 8
Number of packs = 56
Total number of uniforms :
56 * 8 = 448 uniforms
Number of employees who can get uniform :
1 employee = 5 uniforms
Number of employees = 448 / 5 = 89.6
Hence, 89 employees
Yes, (448 - (89*5)
= 448 - 445
= 3 uniforms left

Answer:C
Step-by-step explanation:
Notice that the line is heading downward. This is a clue that it has a negative slope. Think of slope as rise over run. Rise being up or down on the y axis and run being left or right on the x axis. If we start at (0,0) and count down 3 squares and left 4 squares we can see that -3/4 is the slope.
Answer:
A. 3/4
Step-by-step explanation:

which property justifies step 3 Given: 4(x - 6) + 12 = 20
Answer:
x=8
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
4(x−6)+12=20
(4)(x)+(4)(−6)+12=20(Distribute)
4x+−24+12=20
(4x)+(−24+12)=20(Combine Like Terms)
4x+−12=20
4x−12=20
Step 2: Add 12 to both sides.
4x−12+12=20+12
4x=32
Step 3: Divide both sides by 4.
4x

In 1962, the population of a bird species was 2,000.
The population k years after 1962 was 48, and k
satisfies the equation above. Which of the following
is the best interpretation of the number 61 in this
context?
Answer:
61 is the rate at which the population changes every year
Step-by-step explanation:
Given
[tex]2000 - 61k = 48[/tex]
Required
Interpret 61
A linear equation has the form:
[tex]y = mk + b[/tex]
or
[tex]b + mk = y[/tex]
Where m is the rate
By comparison:
[tex]mk = -61k[/tex]
[tex]m = -61[/tex]
Hence, 61 represents the rate at which the population changes yearly.
The negative sign implies that the populatiin reduces

How to calculate 46% of 50
Answer:
the answer is 23
Step-by-step explanation:
100/50=2
46/2=23
Answer:
23
Step-by-step explanation:
50/x=100/46
(50/x)*x=(100/46)*x - we multiply both sides of the equation by x
50=2.17391304348*x - we divide both sides of the equation by (2.17391304348) to get x
50/2.17391304348=x
23=x
x=23
now we have:
46% of 50=23
