Answer:
376 people
Step-by-step explanation:
25% is 94
to get the there 75% divide 94 by 25% or .25 and you get 376. 25% of that is 94.
Alright i believe the answer is 376, to find the answer we need to find the percent of 1/4 and it is 25% so now i must find how many 25's can fit into the 100% or the whole, in this case 4 can fit into it so now i must multiply 94 * 4 = 376
so i think that is the answer is 376...

Which of the following equations are linear?
Hint: Two of them are linear.
1. y = 7/x
2. y = 3x + 4
3. 3x + 4y = 24
Final Answer: They are all Linear
Steps/Reasons/Explanation:
Question: Which of the following equations are linear?
1. [tex]y = \frac{7}{x}[/tex] Linear
2. [tex]y = 3x + 4[/tex] Linear
3. [tex]3x + 4y = 24[/tex] Linear
Because a linear equation is an equation of a straight line, it means that the degree of a linear equation must be 0 or 1 for each of its variables.

did Jeffrey grow than his brother?
Simplify your answer and write it as a fraction or as a whole or mixed number.
Answer:
Jeffrey grew 1/8 inch more than his brother
Step-by-step explanation:
5/8 - 1/2 = 5/8 - 4/8 = 1/8
Answer:
[tex]\frac{5}{4}[/tex] [tex]or[/tex] [tex]1.25[/tex]

Amelia wants to rearrange the furniture in her room. She makes a scale drawing of her rectangular room,
in which every 2 inches represents 5 feet. On her scale drawing, the area of the room is 24.96 square
inches. If one side of her room is 12 feet long, how long is the other side of her room, in feet?
Answer:
The other side = 13 feets long
Step-by-step explanation:
Given that :
Scale of drawing : 2 inches represents 5 feets
Area of rectangular room according to scale drawing = 24.96 in²
Length of one side of the room = 12 feets
Length of other side = x
Area of rectangle = Length * width
If :
2 inches = 5 feets
x = 12 feets
x = (12 *2) / 5
x = 4.8 inches
Hence,
For the scaled drawing :
4.8 * width = 24.96
Width = 24.96 / 4.8
Width = 5.2 inches
Converting to feets according to scale:
2 inches = 5 feets
5.2 inches = x feets
x = (5.2 * 5 ) / 2
x = 13 feets
Other side is 13 feets long
Help plz 13. Mildred is flying a kite on a 30 m string. The angle of elevation of the kite measures 40 degrees,
and Mildred's hand is 2 m above the ground. About how high is the kite off the ground?
a. 21.3 m
c. 19.3 m
b. 25 m
d. 23 m
Answer: 21.3m
Step-by-step explanation:
The height of the kite of the ground would be calculated as:
We have to calculate the question using a right angled triangle that has angle ACB as 90° while angle CAB will be 40°.
Therefore, the height of the kite would be:
= 30 sin 40 + 2
= 30 (0.6428 ) + 2
= 19.284 + 2
= 21.284 m
= 21.3 m
what are 2 ratios equivalent to 2:12
Answer:
possible answers include 1:6 and 4:24
Step-by-step explanation:
think of ratios like fractions. you can simplify a fraction by dividing each number by the same factor. 2/12 = 1/6 because you divide the top and bottom by 2. now, you need ANOTHER response. if you can divide the top and bottom you can also multiply. 2/12 now multiply 2 and 12 by 2 and you get 4/24.
Best answer gets brainiest. Katie's math class starts at 10:15 A.M. and lasts for 1 hour and 55 minutes. After math class, Katie has recess for 35 minutes. What time does Katie's recess end?
Include A.M. or P.M. in your answer.
Answer:
12:45 PM
Step-by-step explanation:
First, add the time of the math class:
10:15 AM + 1 hour
= 11:15 AM
11:15 AM + 55 minutes
= 12:10 PM
Then, add the time of recess:
12:10 PM + 35 minutes
= 12:45 PM
So, her recess ends at 12:45 PM
Answer:
Recess Ends at 12:45 PM
Step-by-step explanation:
10:15 + 1 hour and 55 minute= 12:10 PM
12: 10+ 35 min= 12:45 PM
Independent random samples of released prisoners in the fraud and firearms offense categories yielded the given information on time served in months. At the 1% significance level, do the data provide sufficient evidence to conclude that the meantime served for fraud is less than that for firearms offenses? Assume that populations standard deviations are the same for both groups. (i.e., we assume σ1 = σ2 .)
Answer:
Since the computed value of t= -4.654 does not fall in the critical region we therefore accept the null hypothesis . We conclude that there is sufficient evidence to indicate a difference in the means time served for fraud is less than that for firearms offenses.
Step-by-step explanation:
Fraud Firearm
15.2 9.2 20.1 15.7
11.2 15.8 20.4 9.8
7.2 5.2 13.1 13.5
7.7 4.9 20.7 23.1
7.4 9.8 10.4 22.2
∑ 93.6 169
Fraud (X1i)² Firearm(X2j)²
231.04 84.64 404.01 246.49
125.44 249.64 416.16 96.04
51.84 27.04 171.61 182.25
59.29 24.01 428.49 533.61
54.76 96.04 108.16 492.84
∑1003.79 3079.66
We formulate the null and alternative hypothesis as
H0: μ1 - μ2 ≤ 0 i.e. the fraud meantime is less than that for firearms offenses.
Ha: μ1- μ2 > 0 i.e. the fraud meantime is greater than that for firearms offenses.
We set the significance level at ∝= 0.01
The test statistic, if H0 is true , is
t= x1`1- x`2/ Sp√1/n1+ 1/n2
which has a student t- distribution with ν= n1+ n2 -2 = 18 degrees of freedom
The critical region consists of all t- values which are greater than or equal to t> t(0.01)(18)= 2.522
Computations :
X1`= ∑X1i/n1 = 93.6/10= 9.36
X2`=∑X2j/n2=169/10 = 16.9
∑( X1i- x`1)² = ∑X1i²- (∑X1i)²/n1
= 1003.79 - 876.096/10
= 100.379- 87.6096
=12.7694
∑( X2j- x`2)² = ∑X2j²- (∑X2j)²/n2
= 3079.66 - 28561/10
= 3079.66- 2856.1
=223.56
Sp²= 12.7694+223.56/18= 13.129
Sp = √13.129 =3.623
t= 9.36-16.9/ 3.623√0.1+0.1
t= -7.54/ 1.62
t= -4.654
Conclusion: Since the computed value of t= -4.654 does not fall in the critical region we therefore accept the null hypothesis . We conclude that there is sufficient evidence to indicate a difference in the means time served for fraud is less than that for firearms offenses.
The meantime served for fraud is less than that for firearms offenses.

A customer ordered a product online for $299 and was charged an additional $10 for shipping and handling. The customer received a rebate of $99 and a $25 credit for turning in an old cell phone. After a tax of 4% was applied, how much did the customer pay for the product?
Answer:
the amount paid by the customer for the product is $192.40
Step-by-step explanation:
The computation of the amount paid by the customer for the product is shown below:
= Total amount + Total amount × tax rate
= ($299 + $10 - $99 - $25) + ($299 + $10 - $99 - $25) × 0.04
= $185 + 185 × 0.04
= $185 + $7.4
= $192.40
Hence, the amount paid by the customer for the product is $192.40
We simply applied the above formula so that the correct value could come
