Answer:
s = √227 in
Step-by-step explanation:
A = s²
Where,
A = Area of a square
s = side length of the square
Find the side length of a square with area of 227 in²
A = s²
227 in² = s²
Find the square root of both sides
√227 in² = √s²
√227 in² = s
s = √227 in
Answer:
s = √227 in

Scores on a statewide standardized test are normally distributed with a mean of 12.89 and a standard deviation of 1.95. Certificates are given to students whose scores are in the top 2% of those who took the test. This means that they scored better than 98% of the other test takers. Marcus received his score of 13.7 on the exam and is wondering why he didn’t receive a certificate. Show all work to determine whether Marcus’ score was high enough to earn a certificate. Write a letter to Marcus explaining whether or not he will be receiving a certificate. Include a brief summary of your statistical analysis in your letter.
Answer:
Marcus score is 13.7, the mean is 12.89, and the standard deviation is 1.95, so I’ll do ( 13.7 – 12.89)/ 1.95, Since Marcus' z-score is 0.415. The area to the left of the z-score is 65.9% so therefore Marcus did scored better than 65.9% of the students. So Marcus needs to score 98% better of all the other students in order for him to receive an actual certificate.

The length of 12cm and 5 cm missing one
Answer:
13cm
Step-by-step explanation:
Let the given lengths be the opposte amd adjacent sides of a right triangle'
The missing side will be the hypotenuse
Using the pythagoras theorem;
hyp^2 = 5² + 12²
hyp² = 25 + 144
hyp² = 169
hyp =√169
hyp = 13cm
Hence the missing one is 13cm
5/8+3/4 over this problem(/) -2/3-5/6.
Answer:
5/8 + 3/4= 11/8
-2/3-5/6 =-3/2
Since the second is dividing the first
11/8 ÷ -3/2
Flipping; Then change the bottom to the top(Do this to the second fraction)
11/8 x -2/3
=-11/12.

$3840 with a discount of 10%
Answer: 384
Step-by-step explanation: 10% also equals 0.1 so, 3840*0.1 = 384.
Answer:
$3840
Step-by-step explanation:
10%= x/10 and the x is equal to 3840. 3840/10=384 now that I know what %10 of 3840 I can take off the discount price onto the original price, 3840-384=3456. So 3456 is the final price after including the 10% discount.
Leah needs to order some new supplies for the restaurant where she works. The restaurant needs at least 748 knives. There are currently 214 knives. If each set on sale contains 12 knives, write and solve an inequality which can be used to determine ss, the number of sets of knives Leah could buy for the restaurant to have enough knives.
Answer: s (greater than or equal to) 44.5
Step-by-step explanation:
current # of knives = 214
knives per set = 12
knives needed = 748
# of sets = s
knives per set x (times) # of sets + current # of knives (greater than or equal to) knives needed
12s + 214 (greater than or equal to) 748
SOLVE:
12s + 214 (greater than or equal to) 748
-214 -214
12s (greater than or equal to) 534 you need to divide both sides by 12
s (greater than or equal to) 44.5

find the value of x pls help
Answer:
x = 16
Step-by-step explanation:
*A triangle's interior angles always add up to 180 degrees*
1. The square on the left-hand side means 90 degrees
2. To find the degrees on the 150 degrees side we need to subtract 180 from 150 as the line it's on equals 180 degrees
180 -151 = 29
3. Now we know 3 out of the two angles, so if we add them up and subtract them from 180 degrees we will have the 3rd angle
29 +90 = 119
180 - 119 = 61
4. Now we can put that in with the equation
4x + 3 = 61
5. Solve
4x - 3 = 61
+ 3 +3
4x = 64

A chipmunk population is experiencing exponential growth with a population growth rate of 265 individuals/year, and a per capita rate of increase of 0.15. How many chipmunks are currently in this population
Answer:
There are 1766 chipmunks in the population
Step-by-step explanation:
Number of individuals increasing per year = 265
Rate of increase = 0.15
Rate of increase = increase in number of individuals in a given population /total population
Substituting the given values, we get -
0.15 = (265/total population)
Total population = 265/0.15 = 1766

A random sample of 4 employees will be selected. What are the mean and standard deviation of the sampling distribution of the sample mean for samples of size 4
Answer:
35.2 ; 4.75
Step-by-step explanation:
Given that :
Mean age, μ = 35.2 years
Standard deviation, σ = 9.5 years
The mean of the sampling distribution will be equal to the population mean, μ, this is according to the central limit theorem.
The standard deviation of the sampling distribution, is given by : σ/√n
n = sample size = 4
SD of sampling distribution = 9.5/√4 = 9.5 / 2 = 4.75

If the principal is $4,500 and the rate of interest is 8%, what is the amount of interest after one year? Formula is I =PRT
Step-by-step explanation:
I=?
P= $4500
R=8%=0.08
T=1 year
8%*0.01= 0.08
I=(4500)(0.08)(1)
(4500)(0.08)=360
360*1=360
The interest after one year is $360

Applying the 45-45-90 Theorem, Find the lengths of the other two sides of a right triangle if the length of the hypotenuse is 4√2 inches and one of the angles is 45°.
Rule: If x is the leg of a 45-45-90 triangle, then x*sqrt(2) is the hypotenuse.
We can prove this by showing that x^2+x^2 = (x*sqrt(2))^2 is an identity. It's from the pythagorean theorem a^2+b^2 = c^2.
Put another way, if we know that a = x and b = x are the two congruent legs, then x^2+x^2 = c^2 leads to c = x*sqrt(2). This triangle is known as an isosceles right triangle.
So if 4*sqrt(2) is the hypotenuse, we match that up with the template x*sqrt(2) and see that x = 4 must be the case.
