Graph the line y 3 on the axes shown below. Type of line: Choose one
We need to graph the line:
[tex]y=3[/tex]Notice that there is no restriction on the values of x. So, all the points with y-coordinate 3 belong to that line.
When we graph that line, we obtain:

If Sally has 5 apples, 4 oranges, 3 bananas, 2 grapes, and a plum, how many people does it take to screw in a lightbulb?
Some responses are incorrect. They overlooked the fact that we must eventually add up the cost of one banana.
1 Apple = 7
5 + 7 Equals 12 grapes in a bunch.
After substituting the preceding variables, we arrive to the result that 1 banana equals 2 (7 = 1 + 3 bananas). 21 is incorrect
The second equation has 12 grapes, therefore after solving it, we obtain 1 grape = 1.
However, the final equation has 11 grapes, so we end up with (7+11+2)=20.

Okay, here we have this;
Considering the provided graph, we are going to calculate the requested height, so we obtain the following:
So to calculate the height of the trapezoid, we will replace in the area formula with the given information, so we have:
A=(b1+b2)h/2
10 ft²=(7ft+3ft)h/2
10 ft²*2=(10 ft)h
20 ft²=(10 ft)h
h=20 ft²/10 ft
h=2 ft
Finally we obtain that the height of the ramp is 2ft, then the correct answer is the second option.

A fair die is rolled 4 times. What is the probability of having no 1 and no 3 among the rolls? Round your answer to three decimal places.
Answer:
66.667%
Step-by-step explanation:
In a fair die, there are 6 possible rolls. Out of the 6, 1 number is chosen each time. Since orde does not matter in this problem, we will be applying combination, so this would be written as 6C1 x 4. In order to exclude 3 and 4, from 6, the choices must be narrowed down to 4. Written out as an equation, this would be 4C1 x 4. To get the percentage, simply divide the two equations.
(4C1 x 4)/(6C1 x 4) = 0.66667 = 66.667%

the cost of 12 hot dogs and 8 fry portions is £52. The cost of 8 hot dogs and 12 fry portions is £48. What is the total cost of a hot dog and a portion of fries?
Answer:
Hot dogs cost £3 and fry's cost £2.
Total cost £5.
Step-by-step explanation:
Let a hot dog cost £x and a portion of fry's cost £y.
Then:
12x + 8y = 52
8x + 12y = 48
Simplifying these 2 equations we get:
3x + 2y = 13 ---------- (A)
2x + 3y = 12...............(B)
multiply the first equation by 2 and the second by 3:
6x + 4y = 26
6x + 9y = 36
Subtracting:
0 - 5y = -10
y = -10/-5 = 2.
Now, substituting in equation (A):
3x + 2(2) = 13
3x = 9
x = 3.
A bag contains 6 red marbles and 7 white marbles. Two marbles are drawn in succession without replacement. Find the probabilities of the following events:
1. The first marble drawn is red and the second is white.
2. Both marbles drawn are red.
Using it's concept, the probabilities are given as follows:
1. Red then white: 7/26.
2. Both red: 5/26.
What is a probability?The probability of an event in an experiment is calculated as the number of desired outcomes of the experiment divided by the number of total outcomes of the experiment.
For item 1, we have that:
For the first marble, the probability of it being red is of 6/13, as of the 13 marbles, 6 are red.Supposing that the first marble is red, the probability of the second being white is of 7/12, as of the 12 remaining marbles, 7 are white.Hence the probability is:
6/13 x 7/12 = 7/26.
For item 2, we have that:
For the first marble, the probability of it being red is of 6/13, as of the 13 marbles, 6 are red.Supposing that the first marble is red, the probability of the second being red is of 5/12, as of the 12 remaining marbles, 5 are red.Hence the probability is:
6/13 x 5/12 = 5/26.

Using the compounding formula we can conclude that approximately a 3% of interest rate would be required in order for Jerial to end up with $760.
What is a compound interest?Compound interest, also known as interest on principal and interest, is the practice of adding interest to the principal amount of a loan or deposit. It occurs when interest is reinvested, or added to the loaned capital rather than paid out, or when the borrower is required to pay it so that interest is earned the following period on the principal amount plus any accumulated interest. In finance and economics, compound interest is common.So, the principal amount is $640 and the obtained amount is $760.
Compounded annually for 5 years.Then the interest rate will be:

So far, Benny has run 3/2 miles, but that is only 2/5 of his total running distance. What is his total running
distance?
Step-by-step explanation:
this is 2/5 of his total.
that means we have to divide it by 2 (that delivers 1/5) and multiply by 5 (that delivers 5/5 or 1 = the whole).
in short : multiply by 5/2
3/2 × 5/2 = 15/4 miles = 3 3/4 miles
The scores of 12th-grade students on the National Assessment of Educational Progress year 2000 mathematics test have a distribution that is approximately Normal with mean μ = 300 and standard deviation σ = 35. (a) Choose one 12th-grader at random. What is the probability that his or her score is higher than 300? Higher than 335? Explain and show your work. (b) Now choose an SRS of four 12th-graders and calculate their mean score x. If you did this many times, what would be the mean and standard deviation of all the x-values? Explain and show your work. (c) What is the probability that the mean score for your SRS is higher than 300? Higher than 335? Explain and show your work.
a) To find the probability that the score is higher than 300 you have to find the Z-score for 300, by using the formula:
[tex]\begin{gathered} Z=\frac{x-\mu}{\sigma} \\ Z=\frac{300-300}{35}=\frac{0}{35}=0 \end{gathered}[/tex]The probability of x>300 P(z>0)=1-P(z<=0)
Using the Standard Normal Cumulative Probability Table, P(z<=0)=0.5
Then,
[tex]P(Z>0)=1-0.5=0.5[/tex]Now, you can do the same to find the probability that the score is higher than 335, let' see:
[tex]Z=\frac{335-300}{35}=\frac{35}{35}=1[/tex]The probability of x>335 is P(Z>1), then
[tex]P(Z>1)=1-P(Z\leq1)=1-0.8413=0.1587[/tex]These results mean that it is a 50% of probability that the score of the student chosen is greater than 300, and a 15.87% of probability that the score is greater than 335.
b) SRS=4, their mean score will be the same as the mean of the population = 300, the standard deviation of the sample is the standard deviation of the population divided by √n (n is the size of the sample=4).
[tex]\mu=300\text{ and }\sigma=\frac{35}{\sqrt[]{4}}=17.5[/tex]c) The probability that the mean score for the SRS is higher than 300 is:
[tex]\begin{gathered} Z=\frac{x-\mu}{\sigma} \\ Z=\frac{300-300}{17.5}=\frac{0}{17.5}=0 \end{gathered}[/tex][tex]P(Z>0)=1-P(Z\leq0)=1-0.5=0.5[/tex]The probability that the mean score for the SRS is higher than 335 is:
[tex]Z=\frac{335-300}{17.5}=2[/tex][tex]P(Z>2)=1-P(Z\leq2)=1-0.9772=0.0228[/tex]These results mean that it is a 50% of probability that the mean score of the SRS is greater than 300, and a 2.28% of probability that the mean score is greater than 335.

angela spends $95 to buy 7 cakes for the office party. she cuts each cake into quarters, then cuts each quarter into 3 pieces. if kevin eats 5 pieces of cake during the party, how much did engela spend on just kevins share of the cake
If Angela spent $95 to buy 7 cakes for her office party, and she then cut each cake into quarters and each quarter into further 3 pieces, of which Kevin ate 5 pieces, then Angela had spent $5.65 on just the share of the cake that Kevin had.
As per the question statement, Angela spends $95 to buy 7 cakes for her office party, and she then cuts each cake into quarters and each quarter into further 3 pieces, of which Kevin ate 5 pieces.
We are required to calculate the amount Angela had spent on just the share of the cake that Kevin had.
To solve this question, first let us calculate the total number of pieces, did Angela cut all the 7 pieces of the cake into.
Considering one piece, that it was first cut into a quarter and then each quarter into further 3 pieces, one single piece out of original 7 pieces was cut into a total of [(4 * 3) = 12] pieces.
Therefore, all the 7 original pieces were altogether cut into a total of
[(7 * 12) = 84] pieces.
Now, since Angela spent $95 to buy the original 7 pieces,
Or, Angela actually spent $95 to buy 84 pieces of cake,
Then, 1 piece of the 84 costs $(95/84) = $1.13.
Now, since Kevin ate 5 such pieces of the 84, those 5 pieces cost
$(1.13 * 5) = $5.65.
Therefore, Angela had spent $5.65 on just the share of the cake that Kevin had.
