In The Circle Shown, Chords AC And BD Intersect At E . If AE=8, EC=6, And BE=4. How Long Is DE?10121416

Answers

Answer 1

Answer:

[tex] DE = 12 [/tex]

Step-by-step explanation:

Given:

AE = 8,

EC = 6,

BE = 4.

Required:

Length of DE

SOLUTION:

According to the Intersecting Chords Theorem, [tex] DE \times BE = AE \times EC [/tex]

Plug in the values into the equation. We would have:

[tex] DE \times 4 = 8 \times 6 [/tex]

[tex] DE \times 4 = 48 [/tex]

Divide both sides by 4

[tex] DE = \frac{48}{4} [/tex]

[tex] DE = 12 [/tex]

Hershey's bar were purchased at $7 per dozen and sold at $1.25 each. Find the profit on 15 dozen Hershey's bar.

Answers

Answer:

[tex]Profit = \$120[/tex]

Step-by-step explanation:

Given

[tex]Cost\ Price = \$7[/tex] per dozen

[tex]Selling\ Price = \$1.25[/tex]

Required

Determine the profit on 15 dozen

First, we need to determine the selling price of 1 dozen.

[tex]Selling\ Price = \$1.25 * 12[/tex]

[tex]Selling\ Price = \$15[/tex]

Next, we calculate the profit on a dozen

[tex]Profit = Selling\ Price - Cost\ Price[/tex]

[tex]Profit = \$15 - \$7[/tex]

[tex]Profit = \$8[/tex]

Profit on 15 dozen is:

[tex]Profit = 15 * \$8[/tex]

[tex]Profit = \$120[/tex]

Answers

Answer:

1/2+1/8=5/8

Step-by-step explanation:

The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.

LCD(1/2, 1/8) = 8

Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.

(1/2×4/4)+(1/8×1/1)=?

Complete the multiplication and the equation becomes

4/8+1/8=?

The two fractions now have like denominators so you can add the numerators.

Then:

4+1/8=5/8

This fraction cannot be reduced.

Therefore:

1/2+1/8=5/8

Answers

Note: You probabily forgot to mention the two function. While after some research, I was able to find two functions based on which I would like to solve your query.

Answer:

The y-intercept of the equation will be (0, 4).

Step-by-step explanation:

Considering the assuming functions f(x) and g(x).

[tex]f(x) = -3x - 5[/tex]

[tex]g(x) = f(x)+9[/tex]

So,

[tex]g(x) = (-3x-5)+9[/tex]     ∵ [tex]g(x) = f(x)+9[/tex]

[tex]g(x) = -3x+4[/tex]  

Now, finding the y-intercept

so putting x = 0 in function g(x)

[tex]g(x) = -3(0)+4[/tex]

[tex]g(x) = 0+4[/tex]

[tex]g(x) = 4[/tex]

Therefore, the y-intercept of the equation will be (0, 4).

a. ✓4x²y^4 = ✓4 × ✓x² × ✓y^4

Therefore, ✓4x²y^4 = 2xy²

b. ✓8x²y = ✓8 × ✓x² × ✓y

Therefore, ✓8x²y = 2x✓2y

c. ✓4x²y = ✓4 × ✓x² × ✓y

Find the percent change in the number of scholars who bought lunch from Monday to Tuesday, and indicate whether this was an increase or decrease.

Answers

Answer:

Increase by 10% of students that bought lunch.

Autumn invested $2,800 in an account paying an interest rate of 6.2% compounded
monthly. Assuming no deposits or withdrawals are made, how much money, to the
nearest ten dollars, would be in the account after 8 years?

Answers

Answer: There would be $4590 (approx.) in the account after 8 years.

Step-by-step explanation:

Formula to calculate accumulated amount if compounded monthly :

[tex]A= P(1+\dfrac{r}{12\times100})^{12t}[/tex], where P+ principal value, r = rate of interest , t = time.

Given: P=$2,800 , r = 6.2%

t= 8 years

Substitute all values in the formula , we get

[tex]A=2800(1+\dfrac{6.2}{1200})^{12\times8}\\\\=2800(1+0.005167)^{96}\\\\=2800(1.005167)^{96}\\\\=2800(1.64009619996)=4592.2693\approx4590\text{ [Rounded to the nearest ten dollars] }[/tex]

) If the standard deviation of a random variable X is 15 and a random sample of size n=15 is​ obtained, what is the standard deviation of the sampling distribution of the sample​ mean?

Answers

Answer:

3.8731

Step-by-step explanation:

The standard deviation of the sampling distribution of the sample​ mean is also called the standard error of the mean expressed as;

SM = s/√n

s is the standard deviation of the random variable X

n is the sample size

Given

s = 15

n = 15

Required

Standard deviation of the sampling distribution of the sample​ mean.

Substituting the given parameters into the expression above;

SM = 15/√15

SM = 15/3.8729

SM = 3.8731

Hence the standard deviation of the sampling distribution of the sample​ mean is 3.8731

The graph shows a relationship between the size of 18 households and the average amount of time, in hours, each member of the household spends on chores per week. Which equation best models this data set?

A. y = 0.34x + 5.19
B. y = -0.34x - 5.19
C. y = 0.34x - 5.19
D. y = -0.34x + 5.19

Answers

Answer:

Option (D)

Step-by-step explanation:

Equation to represent the household expenditure per week will be in the form of,

y = mx + b

Where m = slope of the line

b = y-intercept

From the graph attached,

Since, line of best fit touches the positive side of the y-axis, y-intercept will be positive.

Since, y-values on the graph are decreasing with the increase in the x-values,

Slope of the graph will be negative.

[Slope = [tex]\frac{\text{Rise}}{\text{Run}}[/tex], Since rise of the line is negative and run is positive, slope will be negative]

By these properties equation of the linear graph will be,

y = -0.34x + 5.19

Option (D) will be the correct option.

The equation that best models this data set is y = -0.34x + 5.19

A linear equation is in the form:

y = mx + b

where y, x are variables, m is the slope of the line and b is the y intercept.

Let y represent the time spent on chores for x household members.

From the graph, the line passes through (3, 4.25) and (8, 2.5). Hence:

[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-4.25=\frac{2.5-4.25}{8-3}(x-3) \\\\y-4.25=-0.35(x-3)\\\\y=-0.34x+5.2[/tex]

The equation that best models this data set is y = -0.34x + 5.19
