Answer:
1. The probability that she throws a multiple of 3 and flips tails is 1/6
2. The probability that Cymra draws a red marble put it back and draws a red marble again is 25/196
3. The probability that Cole flips three tails in a row, P(3T) is 1/8
4. The number of shots Linda is expected to make if she takes 175 shots is 56
Step-by-step explanation:
1. The number of sides on the special die Li rolls = 12 sides
The numbers on the die are 1 through 12
The number of faces on the penny = 2 (heads and tails)
The number of multiples of 3 on the die = 3, 6, 9, and 12 = 4
The probability that she throws a multiple of 3, P(3) = 4/12 = 1/3
The probability that she flips tails rather than heads = 1/2
∴ The probability that she throws a multiple of 3 and flips tails = 1/3 × 1/2 = 1/6
2. The number red marbles in the bag = 5
The number green marbles in the bag = 6
The number blue marbles in the bag = 3
The total number of marbles in the bag = 5 + 6 + 3 = 14
The probability that Cymra draws a red marble put it back and draws a red marble again is given as follows;
The probability with replacement of picking two red marbles = 5/14 × 5/14 = 25/196
3. The probability that Cole flips three tails in a row P(3T) = (1/2)×(1/2)×(1/2) = 1/8
The probability that Cole flips three tails in a row, P(3T) = 1/8
4. The percentage of times Linda makes her free throws in the past 5 basketball practices = 32%
The number of shots she is expected to make if she takes 175 shots = 175 × 32/100 = 56.
Write the standard form of the equation of the line through the given point with the given slope. point (-1.0); slope -2/3
Answer:
Step-by-step explanation:
When given a point and a slope, the best equation to use is the point-slope formula, y - k = m(x - h)
which here becomes:
y - 0 = m(x + 1), or y = (-2/3)(x + 1), or y = (-2/3)x - 2/3
If you want this in standard form, first clear the fractions by multiplying all terms by 3: 3y = -2x - 2
Now add 2x to both sides, obtaining: 2x + 3y = -2 (in "standard form."
A family has two cars. The first car has a fuel efficiency of 40 miles per gallon of gas and the second has a fuel efficiency of 15 miles per gallon of gas. During
one particular week, the two cars went a combined total of 1625 miles, for a total gas consumption of 50 gallons. How many gallons were consumed by each of
the two cars that week?
Answer:
first car = 35, second car= 15
Step-by-step explanation:
40x+15y=1625
x+y=50
multiplying the 2nd by -15 and add the 2 equations, we get x= 35 and by substituting on second equation we get y= 15

Answer:
[tex]sinC = \frac{7}{25}\\~\\cosC = \frac{24}{25}\\~\\tanC = \frac{7}{24}[/tex]
Step-by-step explanation:
To get the sine of a non-right angle C in a right triangle, just divide the side opposing C by the long side. To get the cosine, divide the sides at C (shorter by longer). To get the tangent, divide the sine by the cosine.
Let's go:
[tex]sinC = \frac{7}{25}\\~\\cosC = \frac{24}{25}\\~\\tanC = \frac{7}{25} / \frac{24}{25} = \frac{7}{24}[/tex]
Answer:
sin(7/25), cos(24/25), tan(7/24)
Step-by-step explanation:
The sin, cos, and tan are found through the sides of the triangle.
The acronym SOH CAH TOA can be used to find which goes where.
S = sin
C = cos
T = tan
O = opposite
A = adjacent
H = hypotenuse
since it asks to use angle C you start from there, for sin its O/H hint by the SOH the rest are the same.

Suppose you invest $4,600 into a savings account with a 8.25% annual interest rate
that compounds interest monthly. Use the TVM solver on your calculator to find the
future value of the account after ten years.
NEED ANSWER ASAP
Answer:
$10,467.06
Step-by-step explanation:
The computation of the future value is shown below:
As we know that
Future value = Present value × (1 + rate of interest)^number of years
here
rate of interest = 8.25% ÷ 12 = 0.6875%
And, the number of years is = 12 × 10 = 120
So, the future value is
= $4,600 × (1 + 0.6875%)^120
= $4,600 × 2.275448086
= $10,467.06

McKenna was asked to write the following expression in standard form.
3−5(3a+6)
When writing the expression in standard from, McKenna made a mistake.
3−5(3a+6)
3+(−5)(3a+6) Step 1
−2(3a+6) Step 2
−6a+(−12) Step 3
−6a−12 Step 4
a. McKenna made her first mistake in ____________
Question 2
b. The correct expression in standard form is ______
basically pls fill in the blanks :]
Answer: -15a - 27
Step-by-step explanation:
McKenna made her first mistake in Step 2. You would need to multiply -5 by 3a and 6, not add it to 3 first.
The correct steps would be:
3−5(3a+6)
3+(−5)(3a+6) Step 1
3 - 15a - 30 Step 2
-15a - 27 Step 3

Silas was curious if sample minimum was an unbiased estimator of population minimum. He started with a large
normally distributed population of test scores whose minimum was 51 points.
He then took a random sample of 6 tests and calculated the minimum of the sample. He replaced those tests
and repeated this process for a total of 40 trials. His results are summarized in the dotplot below, where each
dot represents the minimum score from a sample of 6 tests.

Answer:
Sample minimum appears to be a biased estimator since it consistently overestimated the population minimum.

The graph shown here is the graph of which of the following rational
functions
O A FO) = 2-3x+3
OB. AB) = x= 1962–31x-3
x-2
O C. FX) =
Given:
The graph of rational function.
To find:
The rational function.
Solution:
If the graph of a rational function has a vertical asymptote at [tex]x=a[/tex], then [tex](x-a)[/tex] must be a factor of the denominator of that rational function.
From the given graph it is clear that the graph has two vertical asymptotes. One is at [tex]x=-1[/tex] and another one is at [tex]x=3[/tex].
It means, [tex](x-3)[/tex] and [tex](x+1)[/tex] are the only two factors of the denominator of the rational function.
In option A, the factors of the denominator are different from [tex](x-3)[/tex] and [tex](x+1)[/tex] .
In option B, the denominator has an extra factor [tex]x-2[/tex].
In option C, the denominator has only two factors [tex](x-3)[/tex] and [tex](x+1)[/tex].
Therefore, the correct option is C.
Alejandro and Noya were told to draw a net for an octagonal prism. Which statement about the students' nets is true?
Complete question is;
Alejandro and Noya were told to draw a net for an octagonal prism. Which statement about the students’ nets is true? Both nets do not form octagonal prisms.
A) Only Alejandro’s net is correct.
B) Only Noya’s net is correct.
C) Neither net is correct.
D) Both nets are correct.
Answer:
C) Neither net is correct.
Step-by-step explanation:
From the second attached image, we can see what an octagonal prism looks like when it is opened to show all the faces.
However, looking at the first attached image showing the net drawings of boya and Alejandro, it is very clear that none of them got the required shape for the octagonal prism. Therefore, we can conclude that neither of the nets are correct.

For a school fundraiser, Percy bought a big box of rubber ducks and wrote prize amounts, in dollars, on the bottom of each rubber duck. The prize amounts were $5, $10, $20, $50, and $100. The number of ducks with each prize amount varied so that the total value for all the ducks with each prize amount was always $500.
Percy then put all the rubber ducks in his school’s swimming pool. At the fundraiser, participants used a long net to catch a duck from the pool. They won the amount written on the bottom of the rubber duck, and then they threw the duck back into the pool before the next person’s turn. Since the ducks were returned to the pool after they were caught, the chances of winning any particular amount remained the same.
