At school, 588 students bought a school
shirt, and 147 students did not. What
percent of the students bought a school
shirt?
Answer:
80%
Step-by-step explanation:
Step 1: Add the given data
588 + 147 = 735
Step 2: Divide the number of students who bought a school shirt by the total number of students
588 ÷ 735
= [tex]\frac{735}{588}[/tex]
= 0.8
Step 3: Convert the decimal to fraction
0.8 = 80% (Move the zero 1 place behind the number and remove the ".")
Or
0.8 × 100 = 80%
Therefore, 80% of students bought a school shirt.

A basketball player makes a free throw 82.6% of the time. The player attempts 5 free throws. Use a histogram of the binomial distribution to determine what is the most likely outcome.
Answer:
The most likely outcome is exactly 4 free throws
Step-by-step explanation:
Given
[tex]n = 5[/tex] --- attempts
[tex]p = 82.6\%[/tex] ---- probability of a successful free throw
[tex]p = 0.826[/tex]
Required
A histogram to show the most likely outcome
From the question, we understand that the distribution is binomial.
This is represented as:
[tex]P(X = x) = ^nC_x * p^x * (1 - p)^{n-x}[/tex]
For x = 0 to 5, where x represents the number of free throws; we have:
[tex]P(X = x) = ^nC_x * p^x * (1 - p)^{n-x}[/tex]
[tex]P(X = 0) = ^5C_0 * 0.826^0 * (1 - 0.826)^{5-0}[/tex]
[tex]P(X = 0) = ^5C_0 * 0.826^0 * (0.174)^{5}[/tex]
[tex]P(X = 0) = 1 * 1 * 0.000159 \approx 0.0002[/tex]
[tex]P(X = 1) = ^5C_1 * 0.826^1 * (1 - 0.826)^{5-1}[/tex]
[tex]P(X = 1) = ^5C_1 * 0.826^1 * (0.174)^4[/tex]
[tex]P(X = 1) = 5 * 0.826 * 0.000917 \approx 0.0038[/tex]
[tex]P(X = 2) = ^5C_2 * 0.826^2 * (1 - 0.826)^{5-2}[/tex]
[tex]P(X = 2) = ^5C_2 * 0.826^2 * (0.174)^{3}[/tex]
[tex]P(X = 2) = 10 * 0.682 * 0.005268 \approx 0.0359[/tex]
[tex]P(X = 3) = ^5C_3 * 0.826^3 * (1 - 0.826)^{5-3}[/tex]
[tex]P(X = 3) = ^5C_3 * 0.826^3 * (0.174)^2[/tex]
[tex]P(X = 3) = 10 * 0.5636 * 0.030276 \approx 0.1706[/tex]
[tex]P(X = 4) = ^5C_4 * 0.826^4 * (1 - 0.826)^{5-4}[/tex]
[tex]P(X = 4) = 5 * 0.826^4 * (0.174)^1[/tex]
[tex]P(X = 4) = 5 * 0.4655 * 0.174 \approx 0.4050[/tex]
[tex]P(X = 5) = ^5C_5 * 0.826^5 * (1 - 0.826)^{5-5}\\[/tex]
[tex]P(X = 5) = ^5C_5 * 0.826^5 * (0.174)^0[/tex]
[tex]P(X = 5) = 1 * 0.3845 * 1 \approx 0.3845[/tex]
From the above computations, we have:
[tex]P(X = 0) \approx 0.0002[/tex]
[tex]P(X = 1) \approx 0.0038[/tex]
[tex]P(X = 2) \approx 0.0359[/tex]
[tex]P(X = 3) \approx 0.1706[/tex]
[tex]P(X = 4) \approx 0.4050[/tex]
[tex]P(X = 5) \approx 0.3845[/tex]
See attachment for histogram
From the histogram, we can see that the most likely outcome is at: x = 4
Because it has the longest vertical bar (0.4050 or 40.5%)
What expression is equal to 8 + 2(y + 5)?
10y + 50
10y + 5
2y + 13
2y + 18
Answer:
2y + 18
Step-by-step explanation:
8 + 2(y + 5)
8 + 2y + 10
2y + 18
8+2 (y + 5) = 10 (y+5) = 10y + 50.

A savings account starts with $250. It earns $30 in 2 years. Find the
rate of interest
Answer:
The annual interest rate is 6%
Step-by-step explanation:
Use the formula for simple interest: i = prt.
Set i = prt equal to $30: $30 = prt
Solve this for r:
$30
r = -------------- = ($30) / ($500) = 0.06
$250(2)
The annual interest rate is 6%

In a regular tessellation 3,4,6 sides can be tessellating regular
polygon.
What is regular polygon?A normal tessellation is one made the use of only one regular polygon. A semi-normal tessellation uses or extra ordinary polygons. Triangles and squares, for example, shape ordinary tessellations and octagons and squares for a semi-normal tessellation.
First of all, there are handiest 3 normal tessellations which can be triangles, squares, and hexagons. To make a ordinary tessellation, the inner angle of the polygon has to be a diviser. that is due to the fact the angles need to be introduced as much as so it does now not leave any gaps.
A polygon having identical facets of identical lengths are known as everyday polygons. A ordinary polygon is a polygon that is equiangular i.e. all the angles are equal in measure and equilateral i.e. all facets have the equal length.
A line of symmetry is a line that can be attracted to divide a parent into same halves. A determine has line symmetry or reflection symmetry while it could be divided into identical halves that match. A discern has mirrored image symmetry if it could be meditated throughout a line and look exactly the same as it did earlier than the reflection.

Both diagonal lengths of a kite are multiplied by 3. Which of the following describes the effect of this change on the area? PLZZ HELP!!! THE RED IS THE ONE I GOT WRONG
Answer:
The area is multiplied by 9
Step-by-step explanation:
Since the area of a kite is the two diagonals multiplied together and then divided by two (turn the kite into two triangles if you don't believe me), then the change in area would be from x*y/2 to 3x*3y/2, which is the same as 9x*y/2, i.e. nine times the original area.
Answer:
The correct answer: The area is multiplied by 9.

Answer:
4/11
Step-by-step explanation:
there are 4 green out of 11 total
Answer:
4/11 is the probability you will get a green marble

First you must determine the denominator by adding 4 and 7 to make the total number of marbles
4 + 7 = 11.
Next, you have 4 green marbles so you make it 4/11

Answer:
i saw someone else ask this question i'm trying to remember the answer
Step-by-step explanation:
The mean work week for engineers in start-up companies is claimed to be about 63 hours with a standard deviation of 5 hours. Kara, a newly hired engineer hopes that it's not (she wants it to be shorter). She asks 10 engineers in start-ups for the lengths of their mean work weeks. Their responses are 70; 45; 55; 60; 65; 55; 55; 60; 50; 55. a. Is the newly hired engineer testing a mean or a proportion? proportion mean b. The null hypothesis (or company claim), in symbols, is μ = . c. If the claim is correct, what is the probability that a sample mean would be as low as Kara's mean? % Give your answer as a percentage accurate to one decimal place. d. If Kara will accept the 63 hours as the real average so long as there's at least a 10% chance the sample average value could be as low as hers, should she accept the claim?
Answer:
a. Mean
b. μ = μ₀
c. 11.5%
d. Yes
Step-by-step explanation:
The given parameters are;
The mean work week for engineers, μ₀ = 63 hours
The standard deviation, σ = 5 hours
The number of engineers in Kara's sample, n = 10 engineers
The responses given by the 10 engineers are;
70; 45; 55; 60; 65; 55; 55; 60; 50; 55
a. The given information which the newly hired is hoping to find out that it is not is the mean
b. The null hypothesis which is that the company claim is correct, is therefore;
Null hypothesis, H₀; μ = μ₀ = 63 hours
c. Kara's mean, [tex]\overline x[/tex] is found as follows;
[tex]\overline x[/tex] = (70 + 45 + 55 + 60 + 65 + 55 + 55 + 60 + 50 + 55)/10 = 57
[tex]\overline x[/tex] = 57 hours
The Z-score is therefore;
[tex]Z=\dfrac{\overline x-\mu }{\sigma }[/tex]
Z = (57 - 63)/5 = -1.2
From the Z-table, we have;
The p-value for P([tex]\overline x[/tex] ≤ 57) = P(Z ≤ -1.2) = 0.11507
The probability as a percentage given to one decimal place, that the mean would be as low as Kara's mean, P([tex]\overline x[/tex] ≤ 57) = 11.5%
d. Given that the percent percentage chance (11.5%) that the mean could be as low as hers ([tex]\overline x[/tex] = 57 hours) is higher than 10%, she should accept the claim.
