A team won 13 games, lost 15 games, and tied 2
games. What percent of its games did the team win? I need help please!!
Answer:
43%
Step-by-step explanation:
First, find the total amount of games:
13 + 15 + 2
= 30
Then, to find the percentage of games won, divide 13 by 30:
13/30
= 0.43
So, the team won approximately 43% of its games
Answer: Approximately 43.3%
Work Shown:
13+15+2 = 30 games total
Divide the number of games won (13) over the number total (30)
13/30 = 0.433 approximately which converts to 43.3% of the games won
To convert from decimal form to percent form, move the decimal point over to the right two spaces. Another example would be 0.83 converts to 83%
Which situation represents a non-proportional relationship?
The cost of purchasing p pounds of salmon for $7.99 per pound.
The amount a student makes mowing m number of lawns charging $35 per lawn.
The amount of water draining at a rate of 2.5 gallons per minute.
The total cost of renting a jet ski for $25 per hour plus a fee of $50.
Answer:
Correct option:
"The total cost of renting a jet ski for $25 per hour plus a fee of $50."
Step-by-step explanation:
Proportional relationships are associations between two variables where the ratio of these two variables are correspondent. Or, in a proportional relationship, one variable is a constant value times the other variable. This constant is known as the "constant of proportionality".
The first three options represents a proportional relationship.
But the last option does not.
"The total cost of renting a jet ski for $25 per hour plus a fee of $50."
That is,
TC = 25·h + 50
The relationship is linear not proportional.

Eighty percent of all dentists surveyed agree: Zilch toothpaste tastes best.
Percent of Dentists Surveyed Disagree Agree Do you think this information is misleading? Why or why not?
a. Yes, because it does not state how many dentists were surveyed.
b. Yes, because it does not state on the graph what percentage agrees with the statement.
c. No, because the graph shows eighty percent of the dentists agreeing with the statement. d. No, because it states which toothpaste was used in the survey.
Answer:
a. Yes, because it does not state how many dentists were surveyed.
Step-by-step explanation:
The graph doesn't show how many dentists were actually surveyed, which is a very important factor in interpreting results. Some people could have their own assumptions in this case. Some would think they only surveyed 5 dentists rather than 30 dentists, which affects the percentage or outcome of the result. The sample size in a survey is very crucial when it comes to conducting a research as well as analyzing the result. It will show a transparent distribution of the survey responses.
Answer:
A. Yes, because it does not state how many dentists were surveyed.

find the area of each trapezoid 32 ft x 16 ft 18 ft
Answer:
A = 432 ft^2
Step-by-step explanation:
[tex]A=\frac{a+b}{2} *h[/tex]
A = (32+16)/2 * 18
A = 48/2 * 18
A = 24*18
A = 432 ft^2
ray bd bisects angle abc. solve for x
Answer:
x = 10
Step-by-step explanation:
Since, ray BD bisects ∠ABC,
Therefore, m∠ABD = m∠CBD
By substituting the values of the angles,
x° = (4x - 30)°
x - 4x = -30
-3x = -30
x = 10
Therefore, x = 10 will be the answer.
–sin2(x) = cos(2x) from [–π,π]
I need help on this
If the equation is
- sin²(x) = cos(2x)
rewrite the left side using the Pythagorean identity,
sin²(x) = 1 - cos²(x)
and the right side using the double angle identity for cosine,
cos(2x) = 2 cos²(x) - 1
Then the equation transforms to
- (1 - cos²(x)) = 2 cos²(x) - 1
Solve for cos²(x) :
-1 + cos²(x) = 2 cos²(x) - 1
cos²(x) = 0
Take the square root of both sides to get
cos(x) = 0
Solve for x :
x = cos⁻¹(0) + 2nπ or x = cos⁻¹(0) - π + 2nπ
x = π/2 + 2nπ or x = -π/2 + 2nπ
where n is any integer. We get solutions in the interval [-π, π] when n = 0, giving the solutions
x = π/2 or x = -π/2

Studies indicate that 10.5% of the US population has diabetes. A producer of medical devices is developing a test for diabetes diagnosis: a positive test suggests that a person has diabetes, a negative test suggests that a person does not have diabetes. However, medical tests can give false results: in particular, the probability that this test gives a negative result for a person who actually has diabetes is 0.05, while the probability that the test is positive for a person who in fact does not have diabetes is 0.10.1. What is the probability that the test gives a positive result for a person who is known to have diabetes? 2. What is the probability that a person has diabetes, given that the test gives a positive result?
Answer:
The answer is "0.95 and 0.5271".
Step-by-step explanation:
[tex]p (d) = 0.905 \\\\p( false\ negative) = 0.05\\\\p(false \ positive ) = 0.10 \\\\[/tex]
In point a)
p ( positive diabetes )[tex]= 1 - 0.05 = 0.95[/tex]
In point b)
[tex]p(\frac{d}{+ve}) = \frac{0.105 \times 0.95}{0.105 \times 0.95 +0.895 \times 0.10 }[/tex]
[tex]=\frac{0.09975}{0.09975+0.0895}\\\\=\frac{0.09975}{0.18925}\\\\= 0.5271[/tex]
