N = I ( 1 + 50% )^t
Step-by-step explanation:
Given that The population of Columbus in 2015 was 840,000 people. In 2018 (three years later), The population grew to 972,405 people.
Write an exponential equations that models this situation.
From the question, the following parameters are given :
Initial number of population = 840,000
The new number of population = 972,405
The number of years = 3
Let the initial population = I
The new population = N
And the number of years = t
Since the population is increasing, the exponential equation can be written as
N = I ( 1 + R% )^t
Where R% is the percentage increase.
Solve for R
972405 = 840,000 ( 1 + R% )^3
972405/840000 = ( 1 + R% )^3
1.157625 = ( 1 + R% )^3
( 1 + R% ) = 1.05
Make R% the subject of formula
R% = 1.05 - 1
R% = 0.5
R = 0.5 × 100
R = 50%
Therefore, the exponential equations that models this situation can be expressed as:
N = I ( 1 + 50% )^t

write an equation in slope-intercept form for the line that passes through (-3,1) and is parallel to the line described by y=4x+3
Answer:
y = 4x + 13
Step-by-step explanation:
m = 4 at point (-3,1)
y = 4x + b
1 = 4(-3) + b
1 = - 12 + b
b= 13
y = 4x + 13

The quantities x and y are proportional. Use each of the integers 1-5 to complete the table. **CORRECT ANSWER IS GIVEN BRAINLEST POINTS**
Answer:
x 10 4 6 1
y 5 2 3 0.5
Step-by-step explanation:
You have to start with a guess and see if it works. If it works, you're done. If it doesn't work, you need to make a difference guess.
I'll start by guessing that above the 0.5 is a 1.
If that is correct, then every x value is double the y value below it.
5 goes below the 10. 3 goes below the 6. Then you have 4 and 2 left.
That is every whole number from 1 to 5. It works.
x 10 4 6 1
y 5 2 3 0.5

Step-by-step explanation:
Slope is equal to the change in y over the change in x , or rise over run.
m = change in y /change in x
The change in x is equal to the difference in x-coordinates (also called run), and the change in y is equal to the difference in y-coordinates (also called rise).
m = y 2 − y 1/ x 2 − x 1
Substitute in the values of x and y into the equation to find the slope.
m = 8 − ( 0 ) /3 − ( 1 )
Simplify.
Simplify the numerator.
m = 8 /3 − ( 1 )
Simplify the denominator.
Multiply − 1 by 1
m = 8 /3 − 1
Subtract 1 from 3
m = 8/2
= 4
Josephine wrote the numbers 1-100 and placed them in a bag. If she selects a number without looking, what is the probability that the number is greater than 78? Input your answer as a decimal or fraction.
Answer:
0.22
Step-by-step explanation:
The numbers that would be greater than 78 would include numbers after 78. that is 79, 80 ... 100
The total numbers greater than 78 is 22.
And there are 100 numbers in the bag . the probability of picking a number greater than 78 is 22/100 = 0.22

Erin created a scale drawing for a garden that will be 10 ft by 5 ft. She plans to include a section in the garden for herbs, which will be 2 ft by 5 ft. On Erin’s scale drawing, the entire garden is 12 in. by 6 in. What are the dimensions of the herb garden on the scale drawing?
(GIVING BRAINLIEST) if you solve it
Answer:
The dimensions of the herb garden on the scale drawing are 2.4 by 6 inches
Step 1 (finding the scale factor):
12/10 (inches/feet) or 1.2 (inches/feet)
(1.2 inches in the drawing represent 1 foot in real life)
Step 2 (finding the dimensions of the herb garden on the scale drawing):
Real life dimensions are 2ft by 5ft so we multiply by the scale factor:
2ft = 2 x 1.2 = 2.4 inches
5ft = 5 x 1.2 = 6 inches
So the dimensions of the herb garden on the scale drawing are 2.4 by 6 inches.

Answer:
C. and D.
Step-by-step explanation:
We can cross of A. because if A. were to be correct, nothing else would be correct.
Now we know it has to be B. or C. and D.
D. has to be one of them since you can't have B. and C.
To find out if it is either B. or C. we need to think into it more. So if we had the mean of 80%, that means we need to have some scores over 75%. That would be C. since it says 75% or greater.

If you randomly select a letter from the phrase "Terrace Park Wolves rule," what is the probability that you select a consonant? (Your answer must be in the form of a reduced fraction.)
The probability of selecting a consonant is 0.619
What is Probability?
The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible
The value of probability lies between 0 and 1
Given data ,
The phrase is = "Terrace Park Wolves rule"
The number of letters in the phrase = 21 letters
The number of consonants in the phrase = 13 letters
Now ,
The probability of choosing a consonant from the given set of letters =
number of letters in the phrase / number of consonants in the phrase
Probability of choosing a consonant from the given set of letters = 13 / 21
Probability of choosing a consonant from the given set of letters = 0.619
Hence , The probability of selecting a consonant is 0.619
