A football team won 16 games last year.
This
year the team won 20 games. What
is the
percent increase in the number of
games the team won from last year to this
year?
Answer:
they increased by 25%
Step-by-step explanation:
16/4 = 4. 16+4 = 20. Because of this, the number of wins increased by 4, or 1/4 of last year's wins. this means it increased by 25%.

The sum of three numbers is 103. The second number is 5 less than the first. The third number is 4 times the first. What are the numbers?
Answer:
The numbers are 18, 13, and 72.
Step-by-step explanation:
Let the three numbers be represented by a, b, and c.
The sum of the three is 103. Thus, we can write that:
[tex]a+b+c=103[/tex]
The second number is five less than the first. So:
[tex]b=a-5[/tex]
And the third number is four times the first. So:
[tex]c=4a[/tex]
Substitute:
[tex]a+(a-5)+(4a)=103[/tex]
Solve for a. Combine like terms:
[tex]6a-5=103[/tex]
Add five to both sides:
[tex]6a=108[/tex]
And divide both sides by six. Therefore:
[tex]a=18[/tex]
So, the first number is 18.
Since the second number is five less than the first, the second number is 13.
And since the third number is four times the first, the third number is 72.
If x = -5 and y = 2x^2,
then y = ? *

Given:
Radius of the circle = 4 meters
Measure of arc = 135 degrees
To find:
The area of the sector bounded by the given arc.
Solution:
Formula for area of a sector is:
[tex]A=\pi r^2\times \dfrac{\theta}{360^\circ}[/tex]
Where, r is the radius and [tex]\theta[/tex] is the central angle or measure of intercepted arc.
Putting [tex]r=4,\ \theta =135^\circ[/tex] in the above formula, we get
[tex]A=\pi \times (4)^2\times \dfrac{135^\circ}{360^\circ}[/tex]
[tex]A=\pi \times 16\times \dfrac{3}{8}[/tex]
[tex]A=\pi \times 2\times 3[/tex]
[tex]A=6\pi [/tex]
Therefore, the exact area of the given sector is [tex]6\pi [/tex] square meters.

Answer:
2*(5x+4) + 2*(3x+2)
= 10x + 8 + 6x + 2
= 16x + 10
The perimeter of the rectangle, in feet, is represented by (16x + 10)
Answer:
(16x + 12) ft
Step-by-step explanation:
Perimeter of the rectangle = 5x + 4 + 3x + 2 + 5x + 4 + 3x + 2
Perimeter of the rectangle = (16x + 12) ft

Based on the graph, the values of the constants in the vertex form of the quadratic equation are:
h = 0.k = 20.a = -0.12.How to write a function.Generally, the vertex form of a quadratic equation can be used to model or write an equation of the function of a graph.
Mathematically, the vertex form of a quadratic equation is given by this formula:
y = a(x - h)² + k
Where:
h and k represents the vertex of the graph.
Note: The sign on "a" indicates whether the quadratic equation opens up or opens down.
Based on the complete information, we can deduce that the values of the constants in the vertex form of the quadratic equation are:
h = 0.k = 20.a = -0.12.Read more on vertex here: brainly.com/question/525947

.
Answer:
3yz² - 3z² - 5y + 7
Step-by-step explanation:
Sum of two polynomials = –yz² - 3z² – 4y + 4
One of the polynomial = y - 4yz²- 3
Find the other polynomial
The other polynomial = sum of the polynomials - one of the polynomial
= –yz² - 3z² – 4y + 4 - (y - 4yz² - 3)
= –yz² - 3z² – 4y + 4 - y + 4yz² + 3
= -yz² + 4yz² - 3z² - 4y - y + 4 + 3
= 3yz² - 3z² - 5y + 7

Answer:
17.5 + 15.5
Step-by-step explanation:
17+ 15 = 32
.5 + .5 = 1
32 + 1 = 33
Answer:
15.5 and 17.5
Step-by-step explanation:
Let x and y be the two numbers
x+y = 33
x-y = 2
Add the two equations together
x+y = 33
x-y = 2
-----------------
2x = 35
Divide by 2
2x/2 = 35/2
x = 17.5
Substitute into
x+y = 33
17.5 +y = 33
y = 33-17.5
y = 15.5
Construct the 95% confidence interval estimate of the mean VAS score for patients given the magnet treatment. Find the Standard error and critical value. construct the 95% confidence interval estimate of the mean VAS score for patients given the sham treatment. You may do the shortcut.
Answer:
(3.442 ; 6.558)
Step-by-step explanation:
Given :
Mean score after patient is given the magnet treatment :
Mean score, xbar = 5
Standard deviation, s = 2.4
Sample size, n = 20
The confidence interval :
Mean ± margin of error
Margin of Error = Tcritical * standard error
The critical value at 95%, df = 20 - 1 = 19
Tcritical = 2.093 (T-student distribution)
The standard error = s/√n = 2.4 / √20 = 0.5367
The margin of error = 2.903 * 0.5367 = 1.558
The confidence interval :
Xbar ± Margin of error
5 ± 1.558
(3.442 ; 6.558)
At a coffee shop, the first 100 customers'
orders were as follows.

Medium
Large
Hot

48
22
8
12

Cold
What is the probability that a customer ordered
a cold drink given that he or she ordered a large?
Rounded to the nearest percent, [? ]%
The probability of a customer ordering a cold drink given that they ordered a large is 0.1852 or about 18.52%.
Let us find the individual probabilities.
P(Large | Cold) = 5/25 = 0.2 (out of 25 cold drinks, 5 were large)
P(Cold) = (8+12+5)/100 = 0.25 (out of 100 orders, 25 were cold)
P(Large) = (22+5)/100 = 0.27 (out of 100 orders, 27 were large)
Now we can plug these values into Bayes' theorem:
P(Cold | Large) = 0.2 × 0.25 / 0.27
P(Cold | Large) = 0.1852
Therefore, the probability of a customer ordering a cold drink given that they ordered a large is 0.1852 or about 18.52%.
