Answer:
0.894
Step-by-step explanation:
This would be the area under the standard normal curve to the right of z = -1.25. There are various ways in which we can calculate this area. I will use a TI-83Plus calculator, which features the necessary normalcdf( function:
normalcdf(-1.25, 1000) = 0.894
So: the area under the standard normal curve to the right of z = -1.25 is 0.894. This area also represents the desired probability.

If necessary, round your answer to the nearest tenth.
Answer:
11
Step-by-step explanation:
Answer:
11.4 (This is already rounded to the nearest tenth)
Step-by-step explanation
1.) Add all of them
17+7+13+17+7+9+10=80
2.) Divide the sum by how many numbers there are
In this case, there are 7, so 80/7 is 11.42...
3.) Get the answer
80.7 simplifies into 11.42 so rounded to the nearest 10th is 11.4.
Hope this helped. Good luck on your homework!

The length of Rebecca’s rectangular garden was two times the width “w”. She increased the length and width of the garden so that the area of the new garden is (2w2+7w+6)square yards. By how much did Rebecca increase the length and width of the garden. Show your complete working.
Answer:
rebecca increased the length by 3 and the width by 2
Step-by-step explanation:
First we need to find the length and width by factorizing the expressio ofr the area;
A = 2w^2+7w+6
A = 2w^2+4w+3w+6
A = 2w(w+2)+3(w+2)
A = (2w+3)(w+2)
Since l = 2w
Length = 2w+3
width = w+2
This shows that rebecca increased the length by 3 and the width by 2

Answer:
Step-by-step explanation:
Use SOH CAH TOA to recall how the trig functions fit on a triangle
SOH: Sin(Ф)= Opp / Hyp
CAH: Cos(Ф)= Adj / Hyp
TOA: Tan(Ф) = Opp / Adj
so Sin(x) = d/f
Cos(x) = e/f
Tan(x) = d/e
got it? :)
Answer: sin= d/f
cos= e/f
tan= d/e

Gabriella answered 72 questions correctly on her multiple-choice history final and earned a grade of 36%. How many total questions were on the final exam?
Answer: 200
Step-by-step explanation: cross multiply then divide
The percentage is calculated by dividing the required value by the total value and multiplying by 100.
If 72 questions are 36%.
36% = 72
100% = 200
The total number of questions on the final exam is 200.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
We have,
Number of questions correctly answered = 72
Percentage earned = 36%
This can be written as:
36% = 72
Now,
The total number of questions correctly answered will earn 100%.
This can be written as:
36% = 72
Multiply both sides by 100/36.
100/36 x 36% = 100/36 x 72
100% = 200
This means,
The total number of questions is 200.
Thus
If 72 questions are 36%.
The total number of questions on the final exam is 200.

Given right triangle ABC with altitude BD drawn to hypotenuse AC. If AB=8 and AD=4, what is the length of AC?
Answer:
AC = 16Step-by-step explanation:
In ΔABC & ΔABD
angle ABC = angle ADB ---- (each 90°)
angle BAD = angle CAB ---- (common)
so, therefore
ΔABC ~ ΔABD --- (by AA similarity)
by similarity in ΔABC & ΔABD
AB/AC = AD/AB
8/AC = 4/8
AC = 8×8÷4
AC = 16

Answer:
9.916...
Step-by-step explanation: (The "6" is repeating)
Divide using long division. The whole number portion will be the number of times the denominator of the original fraction divides evenly into the numerator of the original fraction, and the fraction portion of the mixed number will be the remainder of the original fraction division over the denominator of the original fraction.
This gives us a mixed number-fraction: 9 and 11/12.
If we then turn this into a simplified fraction, then it becomes 119/12. Turn that into a decimal by dividing the numerator by the denominator.
This gives us our answer of 9.916...!!! Hope that helps!
