Oh
slant height =15.2 in. height =14 in.base width =12 in .What is the surface area of the pyramid?
Answer: 605.08 hope this helps.
Step-by-step explanation:
PLEASE HELP ME ASAP :)
Answer:
C. 74 sqft
Step-by-step explanation:
The bottom has a surface area of 4ft * 5ft = 20sqft
Theres two 3ft x 5ft sides and two 3ft x 4ft ones.
2 * 3ft * 5ft + 2 * 3ft * 4ft = 2 * 15sqft + 2 * 12sqft = 30sqft + 24sqft = 54sqft
Total surface of the outside is thus
20sqft + 54sqft = 74sqft

TE = 4 + 2x
EV = 4x - 4
Find TE.
Can anyone help with this?
Answer:
TE = 12
Step-by-step explanation:
Given:
TE = 4 + 2x
EV = 4x - 4
The diagonals of the figure bisects each other. This means that:
TE = EV
4 + 2x = 4x - 4
Collect like terms
2x - 4x = -4 - 4
-2x = -8
Divide both sides by -2
x = -8/-2
x = 4
✅Find TE:
TE = 4 + 2x
Plug in the value of x
TE = 4 + 2(4)
TE = 4 + 8
TE = 12

For the area of the rectangle is 10 square inches. Determine both dimensions of the length is 8 inches les than than twice the width. A. Write an equation (in "x") to solve the problem. B. Find the solution(s).
Answer:
x² - 4x - 5 = 0
Width of rectangle = 5 inch
Length of rectangle = 2 inch
Step-by-step explanation:
Given:
Area of rectangle = 10 inch²
Length of rectangle = 2[Width of rectangle] - 8
Find:
Equation
Value of length and width
Computation;
Assume;
Width of rectangle = x
So,
Length of rectangle = 2[Width of rectangle] - 8
Length of rectangle = 2x - 8
Area of rectangle = Length × Width
10 = x(2x - 8)
2x² - 8x - 10 = 0
Divide by 2 from both side
x² - 4x - 5 = 0
x² - (5-1)x - 5 = 0
x² - 5x + x- 5 = 0
x(x - 5) + 1(x - 5)
x = 5 and x = -1
So,
Width of rectangle = 5 inch
Length of rectangle = 2x - 8
Length of rectangle = 2(5) - 8
Length of rectangle = 2 inch
Value at Risk (VAR) has become a key concept in financial calculations. The VAR of an investment is defined as that value v such that there is only a 1 percent chance that the loss from the investment will be greater than v.
(a) If the gain from an investment is a normal random variable with mean 10 and variance 49 determine the VAR. (IfX is the gain, then ?X is the loss.)
(b) Among a set of investments all of whose gains are normally distributed, show that the one having the smallest VAR is the one having the largest value of mean minus standard deviation*2.33?
Answer:
Var = 6.31
Step-by-step explanation:
The Value at Risk (VAR)
[tex]P(X < x_o) = 0.01[/tex]
By using normal distribution
Mean [tex]\mu[/tex] = 10
Variance = 49
Standard deviation [tex]\sigma = \sqrt{49 } = 7[/tex]
This implies that:
[tex]P\Big ( \dfrac{X - \mu}{\sigma } < \dfrac{x_o - \mu }{\sigma}\Big) = 0.01 \\ \\ P\Big ( Z < \dfrac{x_o - \mu }{\sigma}\Big) = 0.01 \\ \\ \dfrac{x_o - \mu }{\sigma} = invNorm(0.01) \\ \\ x_o = \mu + \sigma \times invNorm (0.01)[/tex]
Using the z-table;
[tex]x_o = 10 + 7 \times (-2.33) \\ \\ x_o = -6.3100[/tex]
Hence, there exist 1% chance that X < -6.31 or the loss from investment is > 6.31
From the calculated value above;
[tex]V = \mu -\sigma \times 2.33[/tex]; Since the result is negative, then it shows that the greater the value(i.e the positive or less negative it is ) the lower is the value of VAR. Thus, the least value of VAR is accepted by the largest value of
[tex]min( \mu -\sigma \times2.33,0)[/tex]

Answer:
D) 54.9 cm^2
Step-by-step explanation:
I found the area of the circle wwith the formula A= πr^2
A= π•64
then I found the area of the square, 256
then I subtracted the area of the circle from the area of the square and got approx. 54.9

The two spinners are spun.
Find the probability of getting a 2 and the letter B,
P(2 and B)?
Answer:
P(2 and B) = [tex]\frac{1}{24} = 0.0417[/tex]
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this question, the events getting a 2 and the letter B are independents, so we find each separate probability and multiply them.
Probability of getting a 2:
8 possible values on the spinner, one of which is 2. So
[tex]P(A) = \frac{1}{8}[/tex]
Probability of getting a B:
6 possible values, two of which are B. So
[tex]P(B) = \frac{2}{6} = \frac{1}{3}[/tex]
P(2 and B)?
[tex]P(A \cap B) = P(A)*P(B) = \frac{1}{8}*\frac{1}{3} = \frac{1}{8*3} = \frac{1}{24} = 0.0417[/tex]
P(2 and B) = [tex]\frac{1}{24} = 0.0417[/tex]

=============================================================
Explanation:
Combining all of the angles shown in the diagram leads to 360 degrees. This is because there are 360 degrees in a full rotation.
Let's add up the angles shown and set the sum equal to 360. Keep in mind that the square angle marker represents 90 degrees (aka a right angle).
180+26+x+90 = 180
x+296 = 360
x = 360-296
x = 64

Find the measures of the interior angles of the triangle.
Help PLZ I’ll give you 15 and mark you most brainlyist
Answer:
<A = 45°
<B = 110°
Step-by-step explanation:
Sum of the interior angles of a triangle = 180°
Therefore,
(x + 65)° + 25° + x° = 180°
Solve for x
x + 65 + 25 + x = 180
Add like terms
2x + 90 = 180
2x = 180 - 90
2x = 90
x = 90/2
x = 45°
✔️x + 65 = 45 + 65 = 110°
<A = x = 45°
<B = 110°

Madeline invested $51,000 in an account paying interest rate of 6 1/8% compounded daily. Harper invested 51000 in an account paying an interest rate of 5 3/4% compounded monthly. After 13 years, how much more money would Madeline have in her account than Harper
Answer:
$5564.87
Step-by-step explanation:
We are to determine the difference between the future values of each investment
The formula for calculating future value:
FV = P (1 + r)^mn
FV = Future value
P = Present value
R = interest rate
N = number of years
m = number of compounding
Madeline
P = Present value = 51,000
R = interest rate = 0.06125 / 365 = 0.000168
N = number of years = 13
m = number of compounding = 365
51,000 x (1.000168)^4745 = 113,070.20
Harper
51,000 x (1.004792)^156 = 107,505.33
Difference = 113,070.20 - 107,505.33 = $5,564.87
