pay periods in a year if you get paid every two weeks.
A. 52
B. 26
C. 12
D. 6
Answer:
B.) 26
Step-by-step explanation:
There are 52 weeks in a year.
If you got paid every week there would be 52 pay periods.
But since its every 2 weeks, you cut 52 by half which leaves you with 26.

If you find my answer helpful
Pls consider marking my answer as Brainliest! It would mean a lot!
Answer:
23 miles.
Step-by-step explanation:
This is an equation in words so let's start by putting it into numbers.
we know that John rides his bike for .23 miles and Angie rides her bike a whopping 100 TIMES as far. That means we would multiply.
.23 x 100 = 23
So that means Angie rides her bike for 23 miles.
Hope that helps and have a great day!

Tell which number is prime 19,28,49,63
Answer:
19 is a prime number
Step-by-step explanation:
Answer:
19.
Step-by-step explanation:
The best way to find if a number is prime or not is that you divide that number with 3 and 7 if it is not divisible by either of them then it's a prime. If the one's digit is divisible by 2 it cannot be prime and if the one's digit is 0 or 5 then it is not prime.

Twenty employees have applied for promotions. This year 7 promotions were awarded. If a random sample of 5 applications was selected.
a. What is the probability that at most 2 employees were promoted?
b. What is the probability that no employees were promoted?
c. Find the value of the expected value and the variance of this distribution.
Answer:
a)0.764
b)0.116
c)Expected value =1.75
Variance=1.1375
Step-by-step explanation:
Total Number of employees = 20
Number of promotions awarded = 7
Probability of success p =[tex]\frac{7}{20}[/tex]
Probability of failure q = [tex]1-\frac{7}{20}=\frac{13}{20}[/tex]
We randomly select 5 applications
a) What is the probability that at most 2 employees were promoted?
We will use binomial
[tex]P(X=x)=^nC_r p^r q ^{n-r}\\P(X\leq 2)=P(X=0)+P(X=1)+P(X=2)\\P(X\leq 2)=^{5}C_0 (\frac{7}{20})^0 (\frac{13}{20})^{5-0}+^{5}C_1 (\frac{7}{20})^1 (\frac{13}{20})^{5-1}+^{5}C_2 (\frac{7}{20})^2 (\frac{13}{20})^{5-2}\\P(X\leq 2)=\frac{5!}{0!(5-0)!} (\frac{7}{20})^0 (\frac{13}{20})^{5-0}+\frac{5!}{1!(5-1)!}(\frac{7}{20})^1 (\frac{13}{20})^{5-1}+\frac{5!}{2!(5-2)!} (\frac{7}{20})^2 (\frac{13}{20})^{5-2}\\P(X\leq 2)=0.764[/tex]
b)What is the probability that no employees were promoted?
[tex]P(X=0)=^{5}C_0 (\frac{7}{20})^0 (\frac{13}{20})^{5-0}\\P(X=0)=\frac{5!}{0!(5-0)!} (\frac{7}{20})^0 (\frac{13}{20})^{5-0}\\P(X=0)=0.116[/tex]
c)
[tex]E(X)=np=5 \times (\frac{7}{20})=1.75\\Var(X)=npq=5 \times (\frac{7}{20}) \times \frac{13}{20}=1.1375[/tex]

Find the measures of the numbered angles in the figure, shown to the right. Name the theorem that justifies each
answer.
M<1=
M<2=
M<3=
M<4=
Answer:
Step-by-step explanation:
m∠1 + 75° = 180° [Linear pair of angles]
m∠1 = 180° - 75°
= 105°
m∠2 = m∠1 [Opposite angles of a rectangle are equal]
m∠2 = m∠1 = 105°
m∠2 = m∠3 = 105° [Vertically opposite angles]
m∠3 = m∠4 = 105° [Corresponding angles]
Therefore, all four angles measure the same as 105°.

Describe and correct the error in finding the perimeter or area of the polygon.
Answer:
Look at explanation.
Step-by-step explanation:
The error is that the length of the polygon is 5 not 4. The perimeter should be 16 units not 14 units.
The perimeter of the given polygon is 16 units.
What is the perimeter?The perimeter of a shape is defined as the total distance around the shape. It is the length of the outline or boundary of any two-dimensional geometric shape. The perimeter of different figures can be equal in measure depending upon the dimensions.
From the given figure, length =5 units and width =3 units.
We know that, the perimeter of a rectangle is perimeter =2(length+width)
P= 2l+2w
= 2(5)+2(3)
= 10+6
= 16 units
Therefore, the perimeter of the polygon is 16 units.

A red ball rolls for 6 meters across a sticky level surface and slows down to a stop. the ball was rolling at 36 meters per second when it began to roll across the sticky surface. find the acceleration, velocity final, the velocity initial, the velocity average, the distance the ball rolled, and the time of the balls roll across the sticky surface
Answer:
Please find the answer in the explanation
Step-by-step explanation:
Given that a red ball rolls for 6 meters across a sticky level surface and slows down to a stop. the ball was rolling at 36 meters per second when it began to roll across the sticky surface. To find the acceleration, let us use third equation of motion
V^2 = U^2 + 2as
As the object is moving to stop, V = 0
0 = U^2 - 2as
36^2 = 2 × a × 6
1296 = 12a
a = 1296 / 12
a = 108 m/s
The velocity final = 0
The velocity initial = 36 m/s
the velocity average = (36 + 0)/2
Average velocity = 36/2 = 18m/s
the distance the ball rolled = 6m
and the time of the balls roll across the sticky surface will be achieved by using first equation of motion
V = U + at
V = 0
0 = 36 - 108t
108t = 36
t = 36 / 108
t = 0.3 seconds
The table below gives the stopping distance y (in 100 meters) for a train traveling on a track at various speeds x (miles per hour).
Speed, x (mi/h) 50 55 60 65 70 75 80 85 90
Distance ,y (100m) 20 25 35 50 70 95 125 200 160
Required:
Find an equation of the quadratic function that models the data, and predict the stopping distance for the train traveling at 95 miles per hour.
The required equation is 0.1x²-9.5x+245=0
And, the stopping distance for the train traveling at 95 miles per hour is 245.
What is function?Function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable.
Here, given that,
Speed, x (mi/h) 50 55 60 65 70 75 80 85 90
Distance ,y (100m) 20 25 35 50 70 95 125 160 200
Now, let an quadratic equation be, ax²+bx+c=y
Putting the values of x & y we get,
2500a+50b+c=20 ....(1)
3025a+55b+c=25...(2)
3600a+60b+c=35 .....(3)
solving this we get,
a= 0.1
b=-9.5
c=245
Hence, the required equation is 0.1x²-9.5x+245=0
And, the stopping distance for the train traveling at 95 miles per hour is 245.

When she first measured, Jeremy was 49.5 inches tall, and every month afterward, his height
has increased by 0.75 inch each month.
Which equation models Jeremy's growth spurt, where n represents his height in inches, and
m represents time in months?
Ah 0.75m
B h - 0.75m + 49.5
Ch = 49.5m
Dh = 49.5m + 0.75
Answer:
B

The population of bluegills (type of fish) has a mean length of 152.09mm and a standard deviation of 19.62mm. What is the probability that a random sample of 25 fish has a mean length of 140mm or shorter
Answer:
0.001035
Step-by-step explanation:
Mean (m) = 152.09 mm
Standard deviation (σ) = 19.62 mm
Sample size (n) = 25
Length being 140mm or shorter (x) : x ≤ 140
Using the Zscore relation :
Zscore = (x - m) / (σ/√n)
Zscore = (140 - 152.09) / (19.62/√25)
Zscore = (140 - 152.09) / (19.62/5)
Zscore = −3.081039
P(Z ≤ −3.08) = 0.001035
