Answer:
x = 19
Step-by-step explanation:
Corresponding sides are proportional.
full length/right segment = 36/20 = (x+5+30)/30
Multiplying by 30 gives ...
54 = x +35
19 = x . . . . . . . subtract 35

Answer: We can use equations to represent the measures of the angles described above. One equation might tell us the sum of the angles of the triangle. For example,
X°+145°=180° because there supplementary angles.
X°=35° because 180-145=35°.

A professor of cognitive psychology is interested in the percent accuracy on this memory encoding task among college students. She measures the percent accuracy for 64 randomly selected students. The professor knows that the distribution of scores is normal, but she does not know that the true average percent accuracy on this memory encoding task among college students is 0.794 percent correct with a standard deviation of 0.1110 percent correct.
The expected value of the mean of the 64 randomly selected students, M, is ______ mean and/or standard deviation just given to calculate the expected value of M.) . (Hint: Use the population
The standard error of M is_______ (Hint: Use the population mean and/or standard deviation just given to calculate the standard error.)
Answers
Answer:
Mean of M = 0.794
Standard Error = 0.013875
Step-by-step explanation:
Given that :
Sample size, n = 64
Mean percentage accuracy, μ = 0.794
Standard deviation, σ = 0.1110
Since the distribution of scores is normal ;
Sample mean, m ~ μ
Hence, m ~ 0.794
The sample sta dard deviation of standard error ~ σ/sqrt(n)
Standard Error = 0.1110 / sqrt(64)
Standard Error = 0.1110 / 8
Standard Error = 0.013875

BC ≈ 9.6 mi
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the relationships between sides and angles in a right triangle.
Tan = Opposite/Adjacent
tan(58°) = BC/(6 mi)
BC = (6 mi)tan(58°)
BC ≈ 9.6 mi
Terry goes to the store to buy a shirt. The original price is $32. The shirt is
marked down 20%. When he gets to the check-out stand, he learns that
everything in the store is another 10% off of the marked down price. Which
dollar amount below is closest to the amount Terry paid for the shirt?
Answers
Answer:
The closest amount paid is $23
Step-by-step explanation:
Given
[tex]Price = \$32[/tex]
[tex]Mark\ down = 20\%[/tex]
Amount = 10% of Marked down price
Required
Determine the amount paid
First, we calculate the marked down price P2:
[tex]P_2 = Price(1 - Mark\ down)[/tex]
Substitute values for Price and Mark down
[tex]P_2 = \$32 * (1 - 20\%)[/tex]
Express percentage as decimal
[tex]P_2 = \$32 * (1 - 0.20)[/tex]
[tex]P_2 = \$32 * (0.80)[/tex]
Remove bracket
[tex]P_2 = \$32 * 0.80[/tex]
[tex]P_2 = \$25.6[/tex]
The payable amount is 10% off the marked down price,
This is calculated as:
[tex]Amount = P_2 - P_2 * 10\%[/tex]
Substitute $25.6 for P2
[tex]Amount = \$25.6 - \$25.6* 10\%[/tex]
Express percentage as decimal
[tex]Amount = \$25.6 - \$25.6* 0.10[/tex]
[tex]Amount = \$25.6 - \$2.56[/tex]
[tex]Amount = \$23.04[/tex]
The closest amount paid is $23

please help me work this out! set up and solve a quadratic equation to work out the value of x
Answers
Answer:
x = 8
Step-by-step explanation:
✔️Area of the square = s²
Where,
s = (2x - 4)
Area = (2x - 4)² = (2x - 4)(2x - 4) = 2x(2x - 4) -4(2x - 4)
= 4x² - 8x - 8x + 16
Area of square = 4x² - 16x + 16
Area of rectangle = L × W = (3x - 6) × x
= 3x² - 6x
✔️Since both have the same area, therefore,
4x² - 16x + 16 = 3x² - 6x
Collect like terms
4x² - 3x² - 16x + 6x + 16 = 0
x² - 10x + 16 = 0
Factorize
x² - 2x - 8x + 16 = 0
x(x - 2) -8(x - 2) = 0
(x - 2)(x - 8) = 0
(x - 2) = 0 or (x - 8) = 0
x = 2 or x = 8
If we plug in x = 2 into any of the given side length, we would have 0. (i.e. 2x - 4 = 2*2 - 4 = 0)
So the value of x cannot be 2 because the length of any of the shape cannot be 0.
So therefore, the value of x = 8
