Answer:
? = 14
Step-by-step explanation:
let us say that ? = x
7^x * 7^5^4 = 7^34
When you have a power to a power you multiply
7^x * 7^20 = 7^34
when you multiply common bases you add the power. since all the bases aer the same just look at the power
7^34-20 = 7^x
7^14 = 7^x

What is the solution to this system? Solve by substitution. y= 4x +3 and 2x - 3y = 21
Answers
Answer:
x= -3
y= -9
Step-by-step explanation:
Y-4X =3 ; 2x-3y=21
Y= 3+ 4x
2x -3( 3+4x)= 21
2x- 9- 12x= 21
-10x -9= 21
-10x -9+9= 21+9
-10x = 30
X= 30/-10= -3
Y= 3+4x = 3+ 4* (-3)= 3-12= -9

A to B - just count up the numbers, it's 10
B to C - just count up the numbers, it's 12
A to C - Now this is a right triangle, so use the Pythagorean theorem(10^2 + 12^2 = 244, and take the square root of that, which is 15.62 and round to 15.6
And just add them together 10+12+15.6 to get 37.6

Answer:
x = 5.
y = -2
Step-by-step explanation:
y = x - 7
2x + y = 8
substitute the first equation into the second
2x + (x -7) = 8
2x + x - 7 = 8
3x - 7 = 8
3x = 8 + 7
3x/3 = 15/3
x = 5.
substitute 5 in the second equation
y = 5 - 7
y = -2
x = 5 and y = -2

A physician is testing the effectiveness of wo new exercise plans on 70 subjects. To assign the subjects to the two treatment groups, he writes "Plan 1" on one stip of paper and "Plan 2" on another slip of paper. He randomly picks one of the slips, and assigns the first 35 subjects who signed up to that plan, and assigns the last 35 subjects to the other plan. Select the statement that best describes the composition of the treatment groups.
The treatment groups might not be comparable, because there is not a control group
The treatment groups should be comparable, because there are a large number of subjects in each group.
The treatment groups should be comparable, because the exercise plan for each group was randomly selected
The treatment groups might not be comparable, because the first 35 subjects to sign up for the study might share a characteristic related to exercise, such as high motivation.

Answer:
any coordinate outside the parabola is a reasonable answer.
Step-by-step explanation:
test the solution (0, 0) and if if that number is greater than 0 then the rest of the points outside on the inside are.
x = 0
y = 0
(0)^2 - 2(0) - 3 = -3
-3 is less than 0 so (0, 0) is not a possibility so any coordinate outside the parabola is a reasonable answer.

The numbers of cookies in a shipment of bags are normally distributed, with a mean of 64
and a standard deviation of 4. What percent of bags of cookies will contain between 60
and 68 cookies?
Answers
Answer:
68% i think yeah?
The percent of bags of cookies will contain between 60 and 68 cookies is 68.29%.
What is standard deviation?
A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean.
[tex]\mu[/tex]= 64, [tex]\sigma[/tex]= 4,
[tex]Z_1[/tex]= [tex]X_1[/tex] - [tex]\mu[/tex]/ [tex]\sigma[/tex]
= 60-64/4
= -1
again,
[tex]Z_2[/tex]= [tex]X_2[/tex] - [tex]\mu[/tex]/ [tex]\sigma[/tex]
= 68-64/4
= 1
Thus, P( 60<X<68)
= p(-1<Z<1)
= 0.6829
= 68.29%

George and carmen went on a bicycle trip. They took a bus to their starting point, and then biked the rest. They traveled 350 miles in total, and they biked 80 kilometers more than they were bused.
Answers
Complete question − How many kilometres did they travel by bus and by bicycle.
Answer:George and carmen traveled by bus in 135km and by bikein 215km
Step-by-step explanation:
Total Miles traveled = 350 miles
Let Number of kilometres they traveled with bus = x
and Let Number of kilometres they traveled with bike = x + 80
so that the total distance traveled with bus and bike be expressed as
x + x + 80 = 350 miles
2x + 80 = 350 miles
2x = 350 − 80
2x =270
x=135
George and Carmen traveled by bus in 135km
and by bicycle=x + 80 = 135 km + 80 =215km

A rectangle’s area is calculated with the formula:
A = L * W
To find the length, all we have to do is divide the area (A) by the width (W).
We get the equation:
262.5/21 = L
262.5/21 = 12
L = 12
