Answer:
Step-by-step explanation:
7y+5z-2y+z
Group the two y and the two z together
7y-2y = 5y
5z+z= 6z
(a variable with out a number is = to 1)
so it would be 5y+6z

The exponential regression equation that fits the data is:
[tex]y = 4.981 \times 2.674^x[/tex]
What is an equation?An equation contains one or more terms with variables connected by an equal sign.
Example:
2x + 4y = 9 is an equation.
2x = 8 is an equation.
We have,
Exponential regression is a statistical method used to model relationships between two variables, where one variable is the exponent of another.
In this case, we have two variables, X and Y, and we want to find an exponential function that best fits the data.
The general form of an exponential function is [tex]y = a \times b^x,[/tex]
where a and b are constants.
To find the exponential regression equation that fits the data, we need to find the values of a and b that minimize the sum of the squared errors between the predicted values of Y and the actual values of Y.
Using a software program or a calculator with regression capabilities, we can input the data and find the values of a and b that best fit the data.
In this case, the exponential regression equation that fits the data is:
[tex]y = 4.981 \times 2.674^x[/tex]
This equation has an R-squared value of 0.995,
which indicates a very good fit between the data and the exponential model.
Thus,
The exponential regression equation that fits the data is:
[tex]y = 4.981 \times 2.674^x[/tex]

Can I please have help
To celebrate her birthday, Whitney wants to take her friends adventuring in a 4WD vehicle from All Terrain Tours.
The vehicle can only carry 1700 pounds in total weight. Whitney calculates that the average weight of her friends is 165 pounds. She also thinks that she will need to pack 400 pounds of snacks, drinks, safety equipment etc. Whitney also understands that each person will carry 10 pounds of their own personal gear.
How many friends can Whitney invite?
Write an equation to help you figure out how many friends Whitney can invite to go adventuring with her. Use f as your variable for friends.
PLEASE HELP ASAP
Answer:
Whitney can bring 6 friends.
Step-by-step explanation:
The reason why is this:
Whitney is bringing 400 pounds of things plus her own body weight!
400 + 165 = 565 pounds
Now we add on Whitneys freinds which is 165 (their body weight) + the 10 pounds of gear which equals 175 pounds. So each friend would be 175 pounds total weight.
175 x 6 = 1,050 pounds
If we add on Whitneys total weight thats:
565 + 1,050 = 1,615
Adding on another friend would be 1,790 pounds which would be over the weight limit for the vehicle.
Hence, Whitney can bring along 6 friends for her birthday.
Hope this helped! :)

Sid has a baseball cap collection. 65% of his caps have sports team symbols. If 26 of the caps have the team symbols, how many total caps does Sid have?
39
40
73
91
B. 40
As we know Sid has 26 Caps
we also know that 26 is 65% of total
so let total caps = x
to calculate x
we know that percent = (Values*100)/total Values.......... i
and here Value = 26 caps
percentage = 65
So we have
65 = (26*100)/x---------------- (As we know that per = fraction*100)..... from i
65x= 2600x = 2600/65x=40 capsHence Answer is 40

A right triangle has one leg with a length of 5 units. The hypotenuse is 30 units long. What is the length of the other leg?
A. 5 Units
B. 25 Units
C. V 875
D. V 375
Answer: C. [tex]\sqrt{875[/tex]
Step-by-step explanation:
use Pythagorean theorem [tex]a^{2}+b^{2}=c^{2}[/tex]
a=5 c=30 solve for b
[tex]25+b^2=900[/tex]
subtract 25 from both sides to get [tex]b^2 =875[/tex]
then square both sides to get [tex]\sqrt{875[/tex] for the length of the other leg

In the numbers mumbo jumbo, 76 is the minimum and 89 is the maximum. So it can look like this. (Fig A)
If you understood Fig A, the rest is easy.
There are one 76s, one 77s, four 78s, no 79s, four 80s, five 81s, no 82s, five 84s, four 85s, one 86s, two 87s, one 88s, and two 89s in the mumbo jumbo.
So the completed dot plot would look like Fig B. (I drew this in the computer and the dots aren't presicely balanced, but you'll get the idea)
