Answer:
x = 7
Step-by-step explanation:
log(2^x)=log(128) (Take log of both sides)
x * (log(2)) = log(128)
x = log(128) / log(2)
x = 7

Step-by-step explanation:
Yeah. I need help with this
Answer:
:)
Step-by-step explanation:
well if you take 35x, which is 35 times whatever, + 70, you get y. so the first one is 35(1) + 70 = 105.
so i’ll go in order
35 x 1 + 70 = 105
35 x 2 + 70 = 140
35 x 3 + 70 = 175
35 x 4 + 70 = 210.
just multiply then add 70
hope this helped
What is the rate of change of the function?
A. -3
B. -1/3
C. 1/3
D. 3
Answer:
3
Step-by-step explanation:
The rate of change (which is basically the slope) can be found by dividing the rise/run or the distance up and sideways from a point on a line to another point.
If we go from the first point (0, -4) to the next point on the line (1, -1), we would go up 3 spaces and right one space. 3/1 which would be 3
I hope this helps, i tried to explain the best i could.

IF YOU DONT KNOW THE ANSWERS DONT ANSWER!! ANSWER ALL QUESTIONS 1-5!!
Answer:
D, A, A, B, CStep-by-step explanation:
1.
P(odd) = 3/6 = 1/2
P(blue) = 1/5
P(odd and blue) = 1/2*1/5 = 1/10
2.
Possible outcomes are 9 as all non-zero digits. And 8 is one of them.
P(8) = 1/9
3.
Non-zero digits: 1, 2, 3, 4, 5, 6, 7, 8, 9
5 of them are odd and 4 of them are even.
One digit is discounted as can't repeat and 4 out of remaining 8 are even.
P(even) = 4/8 = 1/2
4.
Remaining marbles: 2 orange, 3 black, 4 pink. Total 9
P(pink) = 4/9
5.
Each spinner has 3 colors.
P(red or orange) = 2/3
P(both red or orange) = 2/3*2/3 = 4/9

Which option identifies which of the two studies described has the more reliable data set and explains why?
Study 1: A survey was conducted 10 times, and the standard deviation was 7.8 percent of the mean.
Study 2: A survey was conducted 100 times, and the standard deviation was 14.5 percent of the mean.
Because the data distribution is more spread out as standard deviation increases, study 1 is more reliable.
Because the margin of error increases as sample size increases, study 1 is more reliable.
Because the data distribution is less spread out as standard deviation increases, study 2 is more reliable.
Because the margin of error decreases as sample size increases, study 2 is more reliable.
Answer:
Study 2 because it has been done 100 times

In one weekend, 2,400 people attend a play at the theater downtown. A survey of 150 people who attended found that 85 gave the play at least 4 stars out of 5.
Write an equation (y=kx) that can be used to predict the number of 4 star ratings the theater will receive.
Use the indicated method to estimate how many people would give the play at least 4 stars?
I need help D:
Step-by-step explanation: 85 is 56.67 percent of 150
56.67 percent of 2,400 is 1360 so 1360 people gave the play at least 4 stars

Answer:
0.6
Step-by-step explanation:
We know that there are 5 counters in total. 3 white and 2 black.
So we know that 3 out of 5 are white and 2 out of 5 are black.
Therefore the chance to get white is 3/5. And for black: 2/5.
We can turn these into decimals, 3/5 = 0.6 (You can make it 6/10 to make it easier.)
And 2/5 = 0.4 (You can make it 4/10 to make it easier.)
Answering the question, you should put your cross/marker on 0.6
Answer:
0.4

A puddle originally contained 2.5 gallons of water. After a hot day, only 1 gallon of water remains.
What is the percent decrease?
Enter your answer in the box.
%
Answer:
60%
Step-by-step explanation:
There is a 60% decrease because 60% of 2.5 = 1.5
So, 2.5 - 1.5 = 1.
Or
1.5/2.5 = 0.60 (which is 60% as a percentage)

A hotel had a number of meeting rooms, m, available for events. Each meeting room has 325 chairs.
Create an equation to represent c, the total number of chairs in all of the meeting rooms in the hotel.
Answer:
mx325=c
Step-by-step explanation:
you would have to multiple the amount of chairs in each room (325) with the amount of rooms there are (m) in order to get the total amount of chairs (c)
Answer:
m x 325 = c
# of rooms x # of chairs in each room = total # of chairs in the hotel
