Answer:
15
Step-by-step explanation:
Fiona (F) = Sushi (S)
Malachy (M) = 7 Fiona (F)
M = F + 90
F + 90 = 7F
6F = 90
F (Fiona) = 15
S (Sushi) = 15
check: Malachy (M) = 15 * 7 = 105
M-F = 105 - 15 = 90

what linear equation in slope intercept from does this graph represent?
Answer:
[tex]y = 16\frac{2}{3} x + 100[/tex] or [tex]y = \frac{50}{3} + 100[/tex]
Step-by-step explanation:
The equation of a line is [tex]y = mx + b[/tex], with [tex]m[/tex] being the slope and [tex]b[/tex] being the y-intercept.
We can see on the graph that the y-intercept, where the line crosses or touches the y-axis, is 100. So, our new equation is [tex]y = mx + 100[/tex].
Now we have to find the slope. Let's pick a point that's clearly on the graph. Perhaps (3, 150). And then we'll take the y-intercept point for convenience, (0, 100).
Then, we'll use [tex]\frac{y_{2} - y_{1}}{x_{2} - x_{1} }[/tex] to find the slope.
Let's substitute in our points.
[tex]\frac{150-100}{3-0}[/tex]
Simplify.
[tex]\frac{50}{3}[/tex]
Now, we can leave the slope like that or turn it into a mixed number. As a mixed number, your slope is [tex]16\frac{2}{3}[/tex].
We'll put that in our equation for a line and...bam!
[tex]y = 16\frac{2}{3} x + 100[/tex] or [tex]y = \frac{50}{3} + 100[/tex]

The price of an item has been reduced by 15%. The original price was $87.
Answer:
The new cost is $73.95
The discount was $13. 05
Step-by-step explanation:
Turn the % into a decimal so it would be 0.15.
Then multiply it to the total, 87 x 0.15 = 13. 05
so the discount subtracted $13.05 off of the original price.
87 - 13. 05 = 73.95
The 7th grade basketball team has won 15 games out of the 20 games they have played this season. If they were to keep up this winning ratio, what is the probability they will win their next game?
Answer: 3/4
Step-by-step explanation:
If three-fifths of seventh-grade class has missed at least one day of school, what percentage of 7th grade has missed at least a day of school?
The percentage of 7th grade class who has missed at least a day of school is 60 percentage.
What is percentage?
A percentage is a number or ratio expressed as a fraction of 100.
It is usually represented by using the symbol %
Given data ,
Fraction of 7th grade class that missed at least one day of school = 3 / 5
Now , to calculate the percentage of 7th grade that has missed at least one day of school , we multiply the fraction by 100
Therefore , Percentage = 3 / 5 x 100 %
= 3 x 20 %
= 60 %
Hence , the percentage of 7th grade class who has missed at least a day of school is 60 percentage.

Consider a binomial experiment with n = 5 trials where the probability of success on a single trial is p = 0.30. (a) Find P(r = 0). (b) Find P(r ≥ 1) by using the complement rule.
Answer:
0.16807 ; 0.83193
Step-by-step explanation:
Given that:
Number of trials, n = 5
Probability of success, p = 0.30
P(r = 0)
Using the binomial probability relation :
P(x =r) = nCr * p^r * (1 - p)^(n - r)
(a) Find P(r = 0).
P(r = 0) = 5C0 * 0.3^0 * (0.7)^(5- 0)
= 1 * 1 * 0.16807
= 0.16807
(b) Find P(r ≥ 1) by using the complement rule
P(r ≥ 1) = 1 - P(r = 0)
P(r ≥ 1) = 1 - 0.16807
P(r ≥ 1) = 0.83193

What is mzA? Enter your answer as only a number
Answer:
A = 25
B = 65
Step-by-step explanation:
Remark
I hope you mean what is the size of <A? If not leave a note. If I am correct than A and C are complementary (equal 90o) since B is a right angle.
Solution
2x + 1 + 5x + 5= 90 Combine like terms
7x + 6 = 90 Subtract 6 from both sides
7x = 90-6
7x = 84 Divide by 7
x = 84/7
x = 12
==========================
Now that is not quite the answer.
A = 2x + 1
A = 2*12 + 1
A = 25
B = 5x + 5
B = 5*12 + 5
B = 60 + 5
B = 65
Many families in California are using backyard structures for home offices, art studios, and hobby areas as well as for additional storage. Suppose that the mean price for a customized wooden, shingled backyard structure is $3,200. Assume that the standard deviation is $1,200. (a) What is the z-score for a backyard structure costing $2,300
Answer:
-0.75
Step-by-step explanation:
To get the z score we have to use this formula
Z = X-mean/standard deviation
X = 2300
Mean = 3200
The standard deviation = 1200
When we plug these values into the z formula above, we have:
2300-3200/1200
= -900/1200
= -0.75
the z-score for a backyard structure costing $2,300 is therefore -0.75

The sum of two numbers is 12 times larger than one set and 29 times larger than the other set. What are those numbers and what is their sum?
Answer:
Step-by-step explanation:
This is a very impossible question to solve because we are not given any idea what both sets are, or at least either of them is. And thus, even if we write down an inequality equation, I doesn't solve the question, it rather makes one ask more questions.
If the two numbers are, say, a and b, and the first set is x, while the second set is y then we have an inequality in the sense that
a + b = 12x
a + b = 29y
How to proceed with no idea what x or y is, is well, not possible

Write 3/5 as a division
Answer:
3/5 as a division is 0.6
Step-by-step explanation:
To write a fraction as a division, we basically divide the values, since the fraction represents a division.
In this question:
We want 3 divided by 5.
3 is less than 5, so we can multiply 3 by 10(getting 30), and adding a 0 to the quotient.
So now 0.(30/5) = 0.6, which means that 3/5 as a division is 0.6.

Solve the following A/5+3=8
Answer:
Your answer is going to be a=1
Step-by-step explanation:
First things first, we want all the letters on the left side and all the numbers on the right side. So, you have to get rid of the three. In order to get rid of the three you have to take it away, so A/5=8-3. Then it will become A/5=5. After that you want to have A all by itself so divide it by 5, A/5=5/5. Then it will become A=1. Hope this helps! :)
Answer:
A=25
