Clare has 8 fewer books than Mai. if mai has 26 books how many books does has Clara have?
Answers
Answer:
18
Step-by-step explanation:
The number of books with Clara is given by the equation C = 18 books
What do you mean by an Equation?Equations are statements in mathematics that have two algebraic expressions on either side of the equals (=) sign.
It displays the similarity of the connections between the phrases on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are examples of the parts of an equation. When creating an equation, the "=" symbol and terms on both sides are necessary.
Given data ,
Let the number of books with Clara be represented as C
Let the number of books with Mai be represented as M
And , Clara has 8 fewer books than Mai
So , the equation is
C = M - 8 be equation (1)
The number of books with Mai , M = 26 books
Now , when M = 26 books
On simplifying , we get
C = 26 - 8
C = 18 books
Therefore , the value of C is 18 books
Hence , the number of books with Clara is 18 books

Find the area of the triangle with vertices: Q(4,4,-1), R(5,7,-2), S(3,2,-4).
Answers
Answer:
The area of the triangle is 5.875 square units.
Step-by-step explanation:
First, we need to calculate the lengths of the triangle by means of Pythagorean Theorem:
[tex]a = \|\overrightarrow {QR}\| = \sqrt{(5-4)^{2}+(7-4)^{2}+(-2+1)^{2}}[/tex]
[tex]a \approx 3.317[/tex]
[tex]b = \|\overrightarrow {RS}\| = \sqrt{(3-5)^{2}+(2-7)^{2}+(-4+2)^{2}}[/tex]
[tex]b \approx 5.745[/tex]
[tex]c = \|\overrightarrow {QS}\| = \sqrt{(3-4)^{2}+(2-4)^{2}+(-4+1)^{2}}[/tex]
[tex]c \approx 3.742[/tex]
Now, we can use the following formula to fid the area of the triangle ([tex]A[/tex]), measured in square units:
[tex]A = \sqrt{s\cdot (s-a)\cdot (s-b)\cdot (s-c)}[/tex]
Where:
[tex]s[/tex] - Semiperimeter of the triangle, dimensionless.
[tex]a[/tex], [tex]b[/tex], [tex]c[/tex] - Sides of the triangle, dimensionless.
The semiperimeter can be determined by this:
[tex]s = \frac{a+b+c}{2}[/tex]
If we know that [tex]a \approx 3.317[/tex], [tex]b \approx 5.745[/tex] and [tex]c \approx 3.742[/tex], the area of the triangle is:
[tex]s = \frac{3.317+5.745+3.742}{2}[/tex]
[tex]s = 6.402[/tex]
[tex]A = \sqrt{(6.402)\cdot (6.402-3.317)\cdot (6.402-5.745)\cdot (6.402-3.742)}[/tex]
[tex]A \approx 5.875[/tex]
The area of the triangle is 5.875 square units.

A homeowners association charges a $3.85 fee for each day your payment is late. If a bull is paid 13 days late, then how much will the homeowners association charge in late fees?
Answers
Answer:
$50.05
Step-by-step explanation:
Since you have to pay $3.85 per day, and you pay it 13 days late, then you would multiply $3.85 and 13.
3.85*13= 50.05
Total amount of late charges fee is $50.05
Given that;Amount pay for late charges = $3.85
Number of days = 13 days
Find:Total amount of late charges fee
Computation:Total amount of late charges fee = Amount pay for late charges × Number of days
Total amount of late charges fee = 3.85 × 13
Total amount of late charges fee = $50.05

Rewrite 4/10 : 1/25 as unit rate
Answers
Answer: 10
Explanation:
remember that when you have a divided fraction, you can change de numerator and denominator so your fractions be like this:
4/10 * 25/1 = 100/10
10*1
100/10= 10
this happens because when you have a fraction that is being divided, it's also like you are cross multiplying, just like the resolution upwards, then you get 100 divided by 10, which is 10.

a parent volunteer group is raising money by making custom hats to sell at school activities.they plan to sell the hats for $10. each hat $4 to make and they spend $50 for advertising.
use n to represent the number of hats they sell. multiply this money by the money for each hat, then subtract that form the advertising cost.
which expression represents the money that the group raised
Answers
Answer:
Money raised($)= 6n-50
Step-by-step explanation:
they plan to sell the hats for $10. each hat $4 to make and they spend $50 for advertising.
If their are no number of hats
Cost = 50+4n
Money gotten from the n number of hats= 10(n)
If they are to make profit, the money gotten from the sales of hats should be bigger than the total cost
Money raised = money from sales- cost
Money raised= 10n -4n-50
Money raised($)= 6n-50
The answer is (10-4)n-50
You subtract the amount of money used to make the hat from the price they are selling the hats. You then multiply that by the number of hats they sold. Then you subtract that from the amount of money spent on advertisement. Therefore the answer is (10 - 4) n - 50

The bad debt ratio for a financial institution is defined to the dollar value of loans defaulted divided by the total dollar value of all loans made. Suppose that a random sample of 7 Ohio banks is selected and that the bad debt ratios (written as percentages) for these banks are 6%, 8%, 5%, 9%, 7%, 5% and 8%. Banking officials claim that the mean debt ratio for all Midwestern banks is 3.5 percent and the mean bad debt ratio for Ohio banks is higher. Set up the null and alternative hypotheses needed to attempt to provide evidence supporting the claim that the mean bad debt ratio for Ohio banks exceed 3.5 percent. (a) H0: μ ≤ [ Select ] % versus Ha: μ > [ Select ] %. (b) Discuss the meanings of a Type I error and a Type II error in this situation. Type I : Conclude that Ohio's mean debt ratio is [ Select ] 3.5 % when it actually is 3.5%. Type II : Conclude that Ohio's mean debt ratio is [ Select ] 3.5 % when it actually is 3.5%.
Answers
Answer:
Step-by-step explanation:
From the information given:
Consider X to be the random variable denoting the bad debt ratios for Ohio Bank.
Then, [tex]X \sim N ( \mu, \sigma ^2)[/tex]
Thus the null hypothesis and the alternative can be computed as:
Null hypothesis:
[tex]H_o : \mu \leq3.5\%[/tex]
Alternative hypothesis
[tex]H_1 : \mu > 3.5\%[/tex]
The type I and type II error is as follows:
Type I:
The mean bad debt ratio is > 3.5% when it is not
Type II:
The mean bad debt ratio is ≤ 3.5% when it is not.
The test statistics can be calculated by using the formula:
[tex]t = \dfrac{\overline x - \mu}{\dfrac{\sigma}{\sqrt{n}}}[/tex]
where;
sample size n = 7
mean = 6+8+5+9+7+5+8 = 48
sample mean [tex]\overline x =\dfrac{48}{7}[/tex]
[tex]\overline x[/tex] = 6.86
sample standard deviation is :
[tex]s = \sqrt{\dfrac{\sum( x -\overline x)^2}{n-1}}[/tex]
[tex]s = \sqrt{\dfrac{( 6 -6.86)^2+( 8-6.86)^2+ ( 5 -6.86)^2 + ...+( 7 -6.86)^2+ ( 5 -6.86)^2+( 8 -6.86)^2 }{7-1}}[/tex]
s = 1.573
population mean [tex]\mu = 3.5[/tex]
Therefore, the test statistics is :
[tex]t = \dfrac{\overline x - \mu}{\dfrac{\sigma}{\sqrt{n}}}[/tex]
[tex]t = \dfrac{6.86- 3.5}{\dfrac{1.573}{\sqrt{7}}}[/tex]
[tex]t = \dfrac{3.36}{\dfrac{1.573}{2.65}}[/tex]
[tex]t = \dfrac{3.36\times {2.65}}{{1.573}}[/tex]
t = 5.660
At significance level of 0.01
[tex]t_{0.01} = 3.707[/tex]
P - value = P(T > 5.66)
P - value = 1 - (T < 5.66)
P - value = 1 - 0.9993
P-value = 0.0007
Therefore, since [tex]t_{0.01} < t[/tex] , we reject the null hypothesis and conclude that the claim that the mean bad debt ratio for Ohio banks is higher than the mean for all financial institutions is true.

Other than itself, what is an angle that is congruent to ∠CFD?
Answers
Answer:
CFB or DFE
Step-by-step explanation:
Congruent angles have the same value in degrees.
Knowing that line DB is straight and CE is perpendicular to DB (at 90 degrees to DB), we know CFD is 90 for the sum of CFD and CFB to equal 180 degrees (since they are on a straight line which is 180 degrees). We also know DFE is 90 for the same reason.
Our question is asking what is congruent or the same angle as CFD. In this case, there are 2 congruent angles: CFB and DFE.
CFB is 90 these angles are on the same line DB and are supplementary (add up to 180 degrees)
DFE is also a correct option since this and CFD are on the line CE and are also supplementary
