Answer:
A. 35
Step-by-step explanation:
The total number of marbles is 25
The number of green & yellow marble is 5
The probability of getting a yellow or green marble (if drawn once) = 5/25
So, if drawn 175 times, 5×175/25 = 35

Answer:
x=3
Step-by-step explanation:
so in order to solve this question we are going to plug in u for 2^x
3((2^x)/2)=2^x+4
3u/2=u+4
3u=2u+8
u=8
we can put 2^x back into the equation in order to find x
2^x=8
2^x=2^3
x=3

Use the scatter plot of car resale values to answer the following question.
A graph titled Car Resale Values has age of car on the x-axis, from 0 to 10 in increments of 2, and percentage of sticker price on the y-axis, for 0 to 100. A line of best fit goes through points (2, 80) and (9, 20).
What can you say about the correlation between the age of a car and its resale value?
a.
The trend line slopes downward from upper left to lower right, so there is a negative correlation between a car’s age and its resale value.
b.
The trend line slopes downward from upper left to lower right, so there is a positive correlation between a car’s age and its resale value.
c.
The trend line slopes upward from lower right to upper left, so there is a positive correlation between a car’s age and its resale value.
d.
There is no correlation between a car’s age and its resale value.

Mr. Rosas had $90 to purchase snacks for a school party. He bought 36 bags of chips and 36 bottles of juice. Each bag of chips cost $0.69, and each bottle of juice cost $1.20. How much money did Mr. Rosas have left after these purchases?
Answer:
$21.96
Step-by-step explanation:
Total money with Mr. Rosas = $90
Total cost of chips = 36*0.69 = $24.84
Total cost of juices = 36*1.20= $43.2
Total money spent = $24.84 + $43.2 = $68.04
Money left with Mr. Rosas
= $90 - $68.04
= $21.96

Step-by-step explanation:
A tourist attraction experienced a 3.75% fall in visitor numbers in June, compared to the previous month due to bad weather There were 121660 visitors in June How many visitors were there in May? B) In July there were 4.5% more visitors than in May What was the percentage increase in visitor numbers from June to July?
Answer:
(A) 126400
(B) 8.57%
Step-by-step explanation:
(A) According to the scenario, calculation of the given data are as follows,
Visitors in June = 121660
Let visitors in May = X
Difference in visitors number in June = 3.75% decrease
So, we can calculate the visitors number in may by using following formula,
Number of visitors in June = X - 3.75%X
121660 = 96.25%X
X = (121660 × 100) ÷ 96.25
X = 126400
Hence, Number of visitors in may = 126400
(B). Difference in visitors in July than in May = 4.5% increase
So, Number of visitors in July = 126400 + (126400 × 4.5%)
= 126400 + 5688
= 132088
Now, we will calculate increase in percentage by using following formula,
Increase percentage = (132088 - 121660) ÷ 121660
= 10428 ÷ 121660
= 0.0857 or 8.57%
If the rectangular screen of a 40-inch monitor is 35 inches wide, what is the height of the monitor? Round to the nearest tenth.
Answer:
19.4
Step-by-step explanation:
We can solve this question using Pythagorean theorem
40^2 = h^2 + 35^2
1600= h^2+ 1225
1600-1225= h^2
375= h^2
h= √375
h = 19.4
Hence the height is 19.4

Answer:
$500
Explanation:
If Joe saved 60% of the cost, given that the amount he saved was $300, to find the total cost of the computer, we need to know 100% of the cost.
60% = $300
[Set the percentage to a fraction and let x be the total cost]
(60/100) x = $300
60x / 100 = $300
_____________
60 → 30 × 2 → 15 × 2 × 2 → 5 × 3 × 2 × 2
______________________________
100 → 50 × 2 → 10 × 5 × 2 → 5 × 2 × 5 × 2
_______________________________
5 × 3 × 2 × 2 / 5 × 2 × 5 × 2 =
3 / 5.
_____________________________
3x / 5 = 300
3x / 5 × 5 = 300 × 5
3x = 1500
÷3 ÷3
x = $500

if p and q vary inversely and p is 17 when q is 15, determine q when p is equal to 5
Answer:
Step-by-step explanation:
q = 51
Writing these statements symbolically, we get p = k/q. This is inverse variation.
Solving for k, we get k = pq. Thus the governing equation is k = pq, or k = (17)(15) = 255.
We then have a specific equation: p = 255/q, or q = 255/p.
If p is 5, q is q = 255/5 = 51

A quality control expert at a drink bottling factory took a random sample of 9 bottles from a
production run of over 1,000 bottles and measured the amount of liquid in each bottle in the
sample. The sample data were roughly symmetric with a mean of 505 mL and a standard
deviation of 6 mL.
Based on this sample, which of the following is a 95% confidence interval for the mean
amount of liquid per bottle (in mL) in this production run?
Answer: It's in the screenshot
Step-by-step explanation:
Using the t-distribution, as we have the standard deviation for the sample, it is found that the 95% confidence interval for the mean amount of liquid per bottle (in mL) in this production run is (500.39, 509.61).
What is a t-distribution confidence interval?The confidence interval is:
[tex]\overline{x} \pm t\frac{s}{\sqrt{n}}[/tex]
In which:
[tex]\overline{x}[/tex] is the sample mean.t is the critical value.n is the sample size.s is the standard deviation for the sample.The critical value, using a t-distribution calculator, for a two-tailed 95% confidence interval, with 9 - 1 = 8 df, is t = 2.306.
The other parameters are given as follows:
[tex]\overline{x} = 505, s = 6, n = 9[/tex]
Hence:
[tex]\overline{x} - t\frac{s}{\sqrt{n}} = 505 - 2.306\frac{6}{\sqrt{9}} = 500.39[/tex]
[tex]\overline{x} + t\frac{s}{\sqrt{n}} = 505 + 2.306\frac{6}{\sqrt{9}} = 509.61[/tex]
The 95% confidence interval for the mean amount of liquid per bottle (in mL) in this production run is (500.39, 509.61).

A human's eyeball is shaped like a sphere with a diameter of 2.5 cm. A
dog's eyeball is shaped like a sphere with a diameter of 1.75 cm. About
how many times greater is the volume of a human's eyeball than the
volume of a dog's eyeball?
Answer:
I think it is 1.5
Step-by-step explanation:
I'm not that sure sorry :(
Volume of human eyeball is 3 times more than volume of dog's eye .
Given,
Human eyeball diameter = 2.5 cm
Dog eyeball diameter = 1.75 cm
Now,
Firstly calculate the volume of humans eye,
Volume of sphere = 4/3 πr³
r = radius of eyeball
r = d/2
r = 2.5/2
r = 1.25 cm
Volume = 2.60π cm³
Now calculate the volume of dogs eye,
V = 4/3 πr³
r = d/2
r = 1.75/2
r = 0.875 cm
V = 0.893π
Thus from the calculation volume of human eye is more by approximately 3 times .
