Answer:
x = 3.431
Step-by-step explanation:
Given equation is,
[tex]5^{(3x-9)}-10=-2[/tex]
[tex]5^{3x-9}-10+10=-2+10[/tex]
[tex]5^{3x-9}=8[/tex]
By taking log on both the sides of the equation,
[tex]\text{log}(5^{3x-9})=\text{log}8[/tex]
(3x - 9)log5 = log8
3x - 9 = [tex]\frac{\text{log}8}{\text{log}5}[/tex]
3x - 9 = 1.292
3x = 9 + 1.292
x = [tex]\frac{10.29202}{3}[/tex]
x = 3.4306
x ≈ 3.431
Pushpin, a social networking site, sent out a survey to all female users. One of the questions in 2014 was, "Do you cook dinner every day?" More than 35,000 women responded, with 38% responding yes. What can you conclude from the survey?
Answer:
We can conclude that of the women who responded to the survey, most of them stated that they do not cook dinner every day. However, it is important to note that there is not much more to be concluded because there are a lot of factors that can go into this. For example, to push feminist perspectives, women may lie about them cooking or be more inclined to respond to the survey (voluntary response bias). Furthermore, women who cook may be less likely to be on the site
Answer:
Undercoverage occurred, so the results tell us little about the population of all adults.
Explanation:
This was targeted to social networking site females, this excludes the population of females who do not use social networking or are unable to. Hope this helps

60% of what number is 150?
Answer:
90
Step-by-step explanation:
To solve this you must make a proportion of x/150 60/100. Then you need to find the relation between 100 and 150 which is x 1.5. Then apply the same thing to 60 which results in 90.
Answer: 250
You must set this up as a proportion
Remember the percent is always over 100
150/x=60/100
Then solve the proportion
60x=15000
Get the x by its self
15000/60 is 250
x=250

An experiment is broken up into two parts. In the first part of the experiment, a six-sided die is rolled. In the second part of the experiment, a dime is tossed in the air. What is the probability of landing on tails?
Answer:
The answer is %50.
Step-by-step explanation:
Since the rolling of the six-sided die and the tossing of the dime are seperate events, their probabilities do not affect each other. Therefore the probability of the dime landing on tails should be %50.

Two rectangular prisms, M and N, are mathematically similar. The volumes of M and N are 17 3 and 136 3, respectively. The height of N is 18 . Find the corresponding height of M.
Answer:
9 cm
Step-by-step explanation:
Volume of M= 17cm^3. Volume of N=136cm^3
Volume of N/Volume of M = k^3
136/17=8
Cube root of 8 =2
Now we know that k=2.
Height of N/2 =height of M
18/2= 9
Therefore, the height of M=9

Answer:
area- 150 , height-12 , base-25
Step-by-step explanation:
multiply the base times height then divide by 2
Answer: The height of the triangle is 12 cm. The base of the triangle is 25 cm. The area of the triangle.... formula: multiply base by height then divide by 2......
so, 25 times 12(height) then divide by 2
Therefore the area is 150 cm.

Miranda and Savannah are excited that a new store just opened in town! They go together the first day it opens!
Each time Miranda goes to the store she plans to spend \$7dollar sign, 7, and each time Savannah goes to the store she plans to spend \$9 dollar sign, 9.
A few weeks from now, Miranda and Savannah are surprised to find out that they have spent the exact same total amount of money at the store.
What is the least possible number of times that Miranda has been to the store?
Answer:
9
Step-by-step explanation:
Given that
Spending done by Miranda each time while go to the store = $7
Spending done by Savannah each time while go to the store = $9
For computing the least possible number we need to take the least common multiple of $7 and $9 i.e to be $63
Now the lease possible number for Miranda has been to the store is
[tex]= \frac{ Lease\ common\ multiple}{Spending\ done \ by\ miranda}[/tex]
[tex]= \frac{\$63}{\$7}[/tex]
= 9
Or we can do one thing as we know that 7 is a prime number which is not cut by any other number except one while the 9 factor could be [tex]= 3\times 3[/tex]
Therefore the 9 times would be considered

The data below represents the number of medals won by the top ten countries in the 2014
Winter Olympics. If the mean is 20.4 and the standard deviation is 7.9, circle all values that
fall within one standard deviation of the mean.
6, 11, 15, 17, 19, 24, 25, 26, 28, 33
Answer:
You should circle:
15, 17, 19, 24, 25, 26, 28
Step-by-step explanation:
The values x that falls within 1 standard deviation of the mean are those which.
[tex]|x - 20.4| \leq 7.9[/tex]
6
|6 - 20.4| = 14.4 > 7.9
6 is not within 1 standard deviation of the mean.
11
|11 - 20.4| = 9.4 > 7.9
11 is not within 1 standard deviation of the mean.
15
|15 - 20.4| = 5.4 < 7.9
15 is within 1 standard deviation of the mean.
17
|17 - 20.4| = 3.4 < 7.9
17 is within 1 standard deviation of the mean.
19
|19 - 20.4| = 1.4 < 7.9
19 is within 1 standard deviation of the mean.
24
|24 - 20.4| = 3.6 < 7.9
24 is within 1 standard deviation of the mean.
25
|25 - 20.4| = 4.6 < 7.9
25 is within 1 standard deviation of the mean.
26
|26 - 20.4| = 5.6 < 7.9
26 is within 1 standard deviation of the mean.
28
|28 - 20.4| = 7.6 < 7.9
28 is within 1 standard deviation of the mean.
33
|33 - 20.4| = 12.6 > 7.9
33 is not within 1 standard deviation of the mean.

What is the base of a triangle with area 50 squared inches and height 3/4 inches to the nearest hundredth?
Answer:
66 2/3 inches
Step-by-step explanation:
The area formula needed here is A = (1/2)(base)(height).
Here A = 50 in^2 and (height) = 3/4 in. We must find the length of the base.
Multiplying both sides of A = (1/2)(base)(height) by 2, we get 2A = (base)(height), or
2A 50 in^2
(base) = -------------- = ----------------- = 66 2/3 inches
(height) 0.75 in

If the factors of quadratic function g are (x − 7) and (x + 3), what are the zeros of function g?
A.
-7 and -3
B.
-3 and 7
C.
3 and 7
D.
-7 and 3
Answer:
The correct option is (b).
Step-by-step explanation:
We are given with the factors of quadratic function. They are as follows :
(x − 7) and (x + 3)
It is required to find the zeroes of function g.
To find zeroes of function, it is required to put the factors equal to 0 i.e.
[tex](x-7)=0\\\\x=7[/tex]
and
[tex](x+3)=0\\\\x=-3[/tex]
From above calculations, we can say that the zeroes of function g are 7 and (-3). Hence, the correct option is (b).
