please help what is the value of
m:
3m:
4m:
5m:
Answer:
Step-by-step explanation:
Consider the center where all the angles meet as the center of a circle. Since a circle is 360 degrees all around, we will add
m + 3m + 5m + 4m = 360 and
13m = 360 so
m = 27.692
Don't know how many decimals you need, but is we round to the nearest hundredth,
3m = 83.07,
4m = 110.76, and
5m = 138.45
What’s -9/25 as a decimal
pls help w give a brainlest
Answer:

Answer:
U h m 17/12- 49/40= 23/120 so i.d.k what to say-
Step-by-step explanation:
Answer:
1/6 or C
Step-by-step explanation:
If you do 17/12 minus 49/40 you will get 23/120.
The question says which choice has a value that is closest to the answer of the expression.
Because of this you could/would round 23 to 20 which is making it 20/120.
If you simplify 20/120 you get 1/6.
Thus, making your answer 1/6.

Shirts are 5% off. The original price of one shirt is $15. What is the total cost, in dollars, of a shirt at the sale price, including a 10% sales tax
Answer:
$15.75
Step-by-step explanation:
[tex]\frac{y}{15} :\frac{5}{100}[/tex]
y × 100 = 5 × 15
100y = 75
100y ÷ 100 = 75 ÷ 100
y = 0.75
$15 - $0.75
$14.25
[tex]\frac{y}{15} :\frac{10}{100}[/tex]
y × 100 = 10 × 15
100y = 150
100y ÷ 100 = 150 ÷ 100
y = 1.5
$14.25 + $1.50
$15.75

Seclect all the sets of numbers that are possible values for x in the inequalit, x > - 8. { -10, -8, -6}. { -8, 0, 8}. { -9, 1, 7}. { -6, -4, -2}
Answer:
{ -6, -4, -2}
Step-by-step explanation:
Since x > - 8, x can be any number greater than - 8.
x = -7, -6, -5, -4,...
BUT, it can't be equal because it's not using this sign [tex]\geq[/tex]
--------------------------------------------------------------------------------
--------------------------------------------------------------------------------
1. { -10, -8, -6} can't be an inequality of x because it has -10, -8.
2.{ -8, 0, 8} can't be an inequality of x because of -8.
3.{ -9, 1, 7} can't be an inequality of x because -9 isn't greater than x.

The revenue of the company is given by the equation R = x (1000 – 4x), where R is the revenue of the company in dollars when thy sell x units of a product. How many units of the product should they sell to make a revenue of $60,000
Answer:
100 or 150 units of the product.
Step-by-step explanation:
R = x(1000-4x)
What is the value of x if R = 60,000?
x(1000-4x) = 60000
-4x^2 + 1000x = 60000
x^2 - 250x = -15000
x^2 - 250x + 15000 = 0
Factorize:
(x-100)(x-150) = 0
x-100 = 0 V x-150 = 0
x = 100 V x = 150

Below is the output from a study to see whether there is evidence of a difference in the mean amounts of time required to reach a customer service representative between two hotels. Assume that the population variances in the amount of time for the two hotels are not equal. What is the smallest level of significance at which the null hypothesis will still not be rejected?
Hotel 1 Hotel 2
Mean 2.214 2.0115
Variance 2.951657 3.57855
Observations 20 20
Hypothesized Mean Difference 0
df 38
t Stat 0.354386
P(T<=t) one-tail 0.362504
t Critical one-tail 1.685953
P(T<=t) two-tail 0.725009
t Critical two-tail 2.024394
Required:
a. State the null and alternative hypotheses for testing if there is evidence of a difference in the variabilities of the amount of time required to reach a customer service representative between the two hotels.
b. What is the value of the test statistic for testing if there is evidence of a difference in the variabilities of the amount of time required to reach a customer service representative between the two hotels? Explain how you obtain your answer.
c. What is the critical value for testing if there is evidence of a difference in the variabilities of the amount of time required to reach a customer service representative between the two hotels at the 5% level of significance?
Solution :
a). [tex]$\text{Set up hypothesis}$[/tex]
[tex]$\text{Null hypothesis}$[/tex] : There is no significance between them.
[tex]$H_0:\mu_1=\mu_2$[/tex]
[tex]$\text{Alternate hypothesis}$[/tex] : There is significance between them.
[tex]$H_1:\mu_1!=\mu_2$[/tex]
b). Test statics
[tex]$X(\text{mean}) = 2.214$[/tex]
Standard deviation [tex]$(s.d1)=1.718; \text{Number}(n_1)=20$[/tex]
[tex]$Y(\text{mean})=2.0115$[/tex]
Standard deviation [tex]$(s.d2)=1.8917; \text{Number}(n_2)=20$[/tex]
We use the test statics :
[tex]$t=\frac{X-Y}{\sqrt{\frac{s.d1^2}{n_1}+\frac{s.d2^2}{n_2}}}$[/tex]
[tex]$t_0=\frac{2.214-2.0115}{\sqrt{\frac{2.95152}{20}+\frac{3.57853}{20}}}$[/tex]
[tex]$t_0=0.35$[/tex]
[tex]$|t_0|=0.35$[/tex]
c. The critical value of |t| with minimum [tex]$(n_1-1)$[/tex] , i.e. 19 d.f is [tex]$2.093$[/tex]
We got [tex]$|t_0|$[/tex] = 0.35439 and |t| = 2.093

Saj has made 7 litres of curry sauce.
He wants to put the curry sauce intojas.
Each jar can be completely filled with 375 millilitres of cury sauce.
Saj wants to completely fill as many jars as possible with cury sence.
How many jars can be fill?
Answer:
18 jars can be filled completely.
Step-by-step explanation:
7L=7000ml
1 jar contain 375 ml
375ml can be filled in 1 jar
375ml=1 jar
1 ml = 1/375 jar
7000 ml = 7000× 1/375 jar
7000ml= 18.67 jar
hence 18 jars can be filled completely.
The total number of jars that can be filled with sauce is A = 18 jars
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
Saj has made 7 litres of curry sauce = 7000 mL
And , each jar can be completely filled with 375 millilitres of cury sauce
So , the number of jars A = 7000 / 375
On simplifying the equation , we get

Answer:

Step-by-step explanation:
I need the answer ....... HELP
Answer:
Below.
Step-by-step explanation:
For the answer including the red historgrams(image 3), the answer is A
this is because there is only 1 value that is between 1-2, which eliminates B. There is 1 value between 2-3 eliminating D. Finally, there is A and C.
C is funky, only having values for .1 to 1.1 for the first frequency. Since ther arent any values between 0.1 and 1.1, this cannot be a ansser.
So its A.
For the 4th image, its D.
This is because it asks what the first segment on the chart means.
The segment is 0-5 miles. This means people drive 0-5 miles . This is the first segment on the chart, and is very short
So we can conclude the answer os:
People drive a short distance to work.
Or as D puts it:
D - The number of people with a short drive to work.
Now we have the last(5th image)
The answer is C.
This is because we look at the values between 0-5, and 0-10.
When looking at the values 0-5, we can see only 3 fit(1, 4, 4)
C has only 1 value between 0-5, and D has 4. This isnt 3, so these cannot be right.
Now we have A and B, which are between 0-10.
There are 4 values we can see fit this(1, 6, 4, 4)
A has 5 values between 0-10, whereas B has 4 values, so it must be B.
For the first image, it says "the data set" implying that it says what this data set is.
For the second image, it is a bit similar.
I couldnt find a way to solve either of these without more information, could you take a picture of the whole entire page, just so I can make sure there isnt any missing info? Thanks, if there just isnt whatsoever, then I honestly have no clue how to do it.
I hope the answrs for 3, 4, and 5th image help!
