The measure of Angle YEA is 70 degrees in the given parallelogram

Given Parallelogram EASY with diagonal ES

∠AES = 40

∠Y = 110

∠ESY = 40   by  Z theorem of a parallelogram

∠A = ∠Y  by property of parallelogram

∠A = <110  as ∠Y=110

∠YES = 180 - ∠Y  

∠YES = 180 - 110 - 40  

∠YES = 30

∠YEA = ∠YES + ∠AES  

∠YEA = 30 + 40            

∠YEA = 70

Hence, the measure of Angle YEA is 70 degrees

Answer:

around 3.3 cm

Step-by-step explanation:

The volume of the rectangular prism cake pan can be calculated by multiplying its length, width, and depth:

V = l × w × d

Substituting the given values, we get:

V = 20 cm × 28 cm × d

V = 560d cm³

We are also given that the amount of batter put into the pan is 1848 cm³. So we can set up the following equation:

1848 cm³ = 560d cm³

Solving for d, we get:

d = 1848 cm³ ÷ 560 cm²

d ≈ 3.3 cm

Therefore, the cake batter is about 3.3 cm deep.

The greatest common factor of the polynomial 2x³ - 10 is 2.

By extracting the greatest common factor, we obtain:

= 2(x³/2 - 5)

Therefore, the factored form of the polynomial is 2(x³/2 - 5).

Thus, the greatest common factor of the polynomial 2x³ - 10 is 2.

Answer:

Sure, here are the steps on how to simplify 2/3 (3x -2) – ¾ (2x -2):

Multiply the factors in the numerator and denominator of each fraction.

2/3 (3x -2) = (2)(3x -2) / (3)(3) = 6x - 4 / 9

¾ (2x -2) = (3/4)(2x -2) / (3) = 3x - 6 / 12

Subtract the numerators of the two expressions.

6x - 4 / 9 - 3x - 6 / 12 = (6x - 4 - 3x - 6) / (9 * 12) = 3x - 10 / 108

Simplify the fraction by dividing the numerator and denominator by 3.

3x - 10 / 108 = (3x - 10) / (3 * 36) = x - 10 / 36

Therefore, the simplified expression is x - 10 / 36.

Step-by-step explanation:

The probability that it takes Jeremiah more than 6 attempts to make his first three-point shot is approximately 0.0479.

The probability that Jeremiah makes a three-point shot is p = 0.25, which means that the probability he misses a shot is q = 1 - p = 0.75.

Let's consider the probability that it takes Jeremiah more than 6 attempts to make his first shot.

This means he must miss the first 6 shots, and make the 7th shot. The probability that he misses a single shot is q = 0.75, so the probability that he misses the first 6 shots is:

P(missing first 6 shots) = q × q × q × q × q × q = (0.75)^6

The probability that he makes the 7th shot is p = 0.25. Therefore, the probability that it takes Jeremiah more than 6 attempts to make his first shot is:

P(MMM > 6) = P(missing first 6 shots) × P(making 7th shot) = (0.75)^6 × 0.25 = 0.0479 (rounded to four decimal places).

ŷ= 6.45x + 31.5 is the equation of the regression line for the given data

Here, we have,

to find the equation of the regression line for a given data:

Construct the table of the data as follows:

5               72            25          5184        360

................................................................................................

20             318           80          17931       1146

.................................................................................................

∑x = 20,  ∑y = 318, ∑x²= 80, ∑xy = 1146,  n = 6 (number data points)

The linear regression equation is of the form:

ŷ = ax + b

where a and b are the slope and y-intercept respectively

a = ( n∑xy -(∑x)(∑y) ) / ( n∑x² - (∑x)² )

a = (6×1146 - 20×318) / ( 6×80-20² )

a = 6876-6360 / 480-400

a = 516 / 80

a = 6.45

x' =  ∑x/n

x' = 20/6 = 10/3

y' = ∑y/n

y' = 318/6 = 53

b = y' - ax'

b = 53 - 6.45×(10/3)

b = 53 - 21.5

b = 31.5

ŷ = ax + b

ŷ= 6.45x + 31.5

Thus,  the equation of the regression line for the given data is

ŷ= 6.45x + 31.5.

(a) x=3 hours

ŷ= 6.45(3) + 31.5 = 50.85

(b) x=4.5 hours

ŷ= 6.45(4.5) + 31.5 = 60.525

(c) x=13 hours

ŷ= 6.45(13) + 31.5 = 115.35

(d) x=1.5 hours

ŷ= 6.45(1.5) + 31.5 = 41.175

To represent a circle with a diameter of 12 units and a center that lies on the y-axis, we can use the standard form of the equation of a circle:

(x - h)^2 + (y - k)^2 = r^2

where (h, k) is the center of the circle, and r is the radius.

If the center of the circle lies on the y-axis, then the x-coordinate of the center is 0. Also, since the diameter is 12 units, the radius is 6 units.

Using these values, we can eliminate the equations that do not meet these conditions:

- x2 + (y – 3)2 = 36: This circle has a center at (0, 3), which is not on the y-axis.

- x2 + (y – 5)2 = 6: This circle has a center at (0, 5), which is not on the y-axis.

- (x – 4)² + y² = 36: This circle has a center at (4, 0), which is not on the y-axis.

- (x + 6)² + y² = 144: This circle has a center at (-6, 0), which is not on the y-axis.

- x2 + (y + 8)2 = 36: This circle has a center at (0, -8), which is on the y-axis.

Therefore, the two equations that represent circles with a diameter of 12 units and a center that lies on the y-axis are:

- x2 + (y + 8)2 = 36

- x2 + (y - 8)2 = 36

Note that the second equation is also valid, since the center of the circle can also be located at (0, -8).

The required solution with the concern of mortgage has been shown below.
$695.67, $250,441.20, $783.93, $235179, and $15262.2.

Using the formula for the monthly payment of a mortgage:

[tex]P = L[c(1 + c)^n]/[(1 + c)^n - 1][/tex]

Here P is the monthly payment, L is the loan amount, c is the monthly interest rate, and n is the total number of payments (in this case, 30 years = 360 months).

Plugging in the values given:

L = 160000

c = 0.033/12 (monthly interest rate)

n = 360

P = 695.67

So the monthly payment is $695.67.

To find out how much will be paid in total over 30 years, we can multiply the monthly payment by the total number of payments:

Total payments = P * n = $695.67 * 360 = $250,441.20

So the total amount paid to the bank for the home over 30 years is $250,441.20.

To calculate the new monthly payment for a 25-year loan, we can use the same formula but with n = 25*12 = 300 months:

P = 160000[(0.033/12)(1 + (0.033/12))^300]/[(1 + (0.033/12))^300 - 1]

P = $783.93

So the new monthly payment for a 25-year loan is $783.93.

The total amount paid over 25 years would be:

Total payments = P * n = $783.93 * 300 = $235179

So the total amount paid to the bank for the home over 25 years is $235179.

The amount saved by reducing the time of the mortgage loan is the difference between the total amount paid for the 30-year loan and the total amount paid for the 25-year loan:

Savings = $250,441.20 - $235179 = $15262.2

So the amount saved by reducing the time of the mortgage loan is $15262.2.

The computation of the interest and the maturity value of the loan, using ordinary interest, is as follows:

Interest = $54.30

Maturity value = $1,404.30.

The ordinary interest method is based on the use of 360 days as the ordinary days in a calendar year.

The ordinary interest contrasts with the exact interest, which uses 365 days or the normal calendar days.

Principal = $1,350

Interest rate = 8%

Date borrowed = July 21

Date repaid = January 18

The number of days between July 21 and January 18 = 181 days

Total Interest = Principal x Rate x Time

= $54.30 ($1,350 x 8% x 181/360)

Maturity value = Principal + Total Interest

= $1,404.30 [$1,350 + ($1,350 x 8% x 181/360)]

Thus, based on the ordinary interest method, the maturity value of the loan is $1,404.30.

Answer: 57 cm²

Step-by-step explanation:

To answer this question, we need to find the surface area of the figure.

First, we will find the surface area of the bottom part, the rectangular prism. We will use the given formula. However, we do not count the top side since it is connected to the bottom part. We will subtract this.

       SA = 2(wl + hl + hw)

       SA = 2((3 cm)(3 cm) + (2 cm)(3 cm) + (2 cm)(3 cm))

       SA = 42 cm²

       SA = 42 cm² - 9 cm² = 33 cm²

Next, we will find the surface area of the top part, the square pyramid. We know we have four congruent triangles. We will not count the square base since it is connected to the bottom part.

       SA = 4 * ([tex]\frac{bh}{2}[/tex])

       SA = 2 * (bh)

       SA = 2 * ((3 cm)(4 cm))

       SA = 2 * (12 cm²)

       SA = 24 cm²

Lastly, we will add these two parts together.

        33 cm² + 24 cm² = 57 cm²
