A college-entrance exam is designed so that scores are normally distributed with a mean of 500 and a standard deviation of 100. You scored a 625. Calculate your z-score to the nearest hundredth (i.e. 2 decimal places).
z=
Answer: 1.25
Step-by-step explanation:
Given: A college-entrance exam is designed so that scores are normally distributed with a mean[tex](\mu)[/tex] = 500 and a standard deviation[tex](\sigma)[/tex] = 100.
A z-score measures how many standard deviations a given measurement deviates from the mean.
Let Y be a random variable that denotes the scores in the exam.
Formula for z-score = [tex]\dfrac{Y-\mu}{\sigma}[/tex]
Z-score = [tex]\dfrac{625-500}{100}[/tex]
⇒ Z-score = [tex]\dfrac{125}{100}[/tex]
⇒Z-score =1.25
Therefore , the required z-score = 1.25

Naika took out a $29,300 5 year Federal Loan with an interest rate of 3.22%. She will
have to pay the loan back when she graduates in 4 years. The loan also gives her a
grace period of 12 months after graduation before she has to start making payments.
How much interest will accrue before she begins making payments on the loan?
9514 1404 393
Answer:
$4717.30
Step-by-step explanation:
Assuming the interest is capitalized only at the start of repayment, the accrued interest is ...
I = Prt
I = ($29,300)(0.0322)(4 +1) = $4717.30
The accrued interest is $4717.30.

What is the value of x in the following equation?
7 = 2x^2 - x - 8 + x - 3
Answer:3,-3
Step-by-step explanation:
begin by simplifing the expression. So, the 2 x's will cancel out in the expression. you should have 7=2x^2-11. Then Subtract the 7 from both sides so you cna use the quadratic formula. This gives you 2x^2-18=0. Using the formula {-b+/sqrt(b^2-4ac)}/2a this gives us {-0+/sqrt(0^2-4*2*-18)}/2*2 this simplifies to 0+/- 12 all over 4. +12/4=3 and -12/4=-3.
A rectangular prism has a length of 112feet, a width of 212feet, and aheight of 8 inches. What is the volume of the prism in cubic inches?
pls hurry :)
Answer:
27,353,088 cubic inches
Step-by-step explanation:
How to find the volume of a rectangular prism
To find the volume of a rectangular prism, multiply its 3 dimensions: length x width x height. The volume is expressed in cubic units.
Solve
In this case, The volume of a rectangular prism with a length of 112feet,
width of 212 feet, and height of 8 inches:
But in this case, we need to convert both the length and width to inches.
If 1ft = 12in
Then, 112ft = 1344in (Multiply 112 by 12)
Also, 212ft = 2544 (Multiply 212 by 12)
So, the volume = 1344 x 2544 x 8
Calculated out this gives a volume of 27,353,088 cubic inches.

PartA: Explain why x=6makes 4x-5< 19.
Answer:
It doesn't.
Step-by-step explanation:
If you plug in 6 in the x spots you will have:
4(6)-5 < 19If you solve that, you will get:
19< 19So considering that they are the same number, this doesn't make sense because it should be an equal sign.

3.is "A"
4.is "C"
* By definition, the sum of the interior angles of a triangle is 180 degrees.
* Keeping this in mind, you have:
As you can see, the sum of the other two angles must be 108 degrees, then, let's add the angles given in each option:
A) 9°+9°=18
B) 26°+46°=72°
C)53°+55°=108°
D)72°+108°=180°
*Therefore, the answer is option C.
5.is "B"
A triangle is called a right triangle when one of it's angles measures 90°.
We have been given the second angle as 14°.
The angles in a triangle add up to 180°.
∴ letting the third angle to be X;
X + 14° + 90° = 180°
X + 104° = 180°
X = 180° - 104°
= 76°
7. the answer is "B"
A = 41 * 14 / 2
A = 574 / 2
A = 287 cm²
So, the area of the trapezoid is 287 cm².
9. is "B"
Area = base x height
Or 356.25=14.25 x Height
Dividing both sides by 14.25
Height =25inches
.Height of the parallelogram is 25 inches. the answer is "B"
10.is "B"
the sum of any 2 sides of a triangle must be greater than the third side
