Answer:

20.8

Step-by-step explanation:

Let h be the height of the ladder. We know that the distance BC is 8 ft, and the angle of elevation BAC is 69 degrees. Therefore, we have:

tan(69) = h/8

Multiplying both sides by 8, we get:

8*tan(69) = h

Using a calculator, we get:

h ≈ 20.8 ft

Therefore, the height of the top of the ladder from the ground is approximately 20.8 feet.

The Iength οf the diagοnaI οf the square exteriοr waII shοuId be 15 feet.

Accοrding tο the Pythagοrean theοrem, the square οf a right triangIe's hypοtenuse (the side οppοsite the right angIe) equaIs the sum οf its οther twο sides' squares.

Outside waII's Iength and width are equaI if it is a square. Let's caII this Iength "x"

Using the Pythagοrean theοrem, we can find the Iength οf the diagοnaI οf the square:

diagοnaI² = height² + width²

Since the height is 9 ft and οne side οf the square is 12 ft, we can write:

diagοnaI² = 9² + 12²

diagοnaI² = 81 + 144

diagοnaI² = 225

Taking the square rοοt οf bοth sides, we get:

Answer:

Step-by-step explanation:

To simplify the expression, we can use the distributive property of multiplication:

(x−3)(2x^2 −5x−5) = 2x^3 −5x^2 −5x −6x^2 +15x +15

Next, we can combine like terms:

2x^3 −5x^2 −6x^2 −5x +15x +15 = 2x^3 −11x^2 +10x +15

Therefore, the simplified polynomial in standard form is 2x^3 −11x^2 +10x +15.

The probability that the mean weight for 100 boys in the 5th grade will be between 60 and 70 pounds is approximately 0.674.

According to the central limit theorem, a statistical theory, regardless of the population distribution's form, the distribution of sample means tends to resemble a normal distribution as sample size grows. This implies that the distribution of the sample means will be about normal if we take several random samples from a population.

Given that, mean weight for 100 boys in the 5th grade will be between 60 and 70 pound.

The z-score is given as:

z = (x - μ) / (s / √(n))

Substituting the values:

z = (70 - 64.9) / (17.5 / √(100)) = 1.143 = 0.674

z = (60 - 64.9) / (17.5 / √(100)) = -1.143 =0.674

Hence, the probability that the mean weight for 100 boys in the 5th grade will be between 60 and 70 pounds is approximately 0.674.

4 number was not used in the statement. we can use -3 as the other value.

A simple statement is a single assertion that can be classified as true or false, while a compound statement is formed by combining two or more simple statements using logical operators such as "and", "or", and "not".

To explain the statement mathematically:

First, we evaluate N/N:

N/N = 1

Next, we simplify the inequality using this value:

1•N < N - 1 < N - N

Simplifying further, we get:

N < N - 1 < 0

We can then substitute the values of -4 to 4 for N and see which value(s) satisfy the inequality.

If N = -4, then we have:

-4 < -5 < 0

This is true, so we can use -4 as one of the values.

If N = -3, then we have:

-3 < -4 < 0

This is also true, so we can use -3 as the other value.

Answer:

C)  2, 7, 6 can form a triangle.

Step-by-step explanation:

The triangle inequality theorem states that the sum of any two sides of a triangle is greater than the length of the third side.

To determine which group of given side measures will form a triangle, sum each pair of sides and compare to the third side. If all three inequalities are true, the group will form a triangle.

Given side lengths: 9, 4, 3

  ⇒ 9 + 4 > 3

  ⇒ 9 + 3 > 4

  ⇒ 4 + 3 [tex]\ngtr[/tex] 9

Therefore, this group cannot form a triangle.

Given side lengths: 8, 1, 7

  ⇒ 8 + 1 > 7

  ⇒ 8 + 7 > 1

  ⇒ 1 + 7 [tex]\ngtr[/tex] 8

Therefore, this group cannot form a triangle.

Given side lengths: 2, 7, 6

  ⇒ 2 + 7 > 6

  ⇒ 2 + 6 > 7

  ⇒ 7 + 6 > 2

Therefore, this group can form a triangle.

Given side lengths: 12, 10, 22

  ⇒ 12 + 10  [tex]\ngtr[/tex] 22

  ⇒ 12 + 22 > 10

  ⇒ 10 + 22 > 12

Therefore, this group cannot form a triangle.

The statement which best describe the correct null and alternative hypotheses, the test statistic, and conclusion at a significance level of 0.05 is:

D. H₀: μ₁ = μ₂ H₁: μ₁ < μ₂.

test statistic, t = -1.5625.

conclusion: fail to reject the null hypothesis μ₁ = μ₂.

Based on the information provided, the appropriate null hypothesis and alternative hypothesis would be represented by the following mathematical expression:

H₀: μ₁ - μ₂ ≤ 0; μ₁ = μ₂

H₁: μ₁ - μ₂ < 0; μ₁ < μ₂.

For the critical value, we have:

Critical probability (p*) = 1 - α

Critical probability (p*) = 1 - 0.05

Critical probability (p*) = 0.9500.

Based on the distribution table for probabilities, a value that corresponds to 0.9500 can be calculated as follows;

Zα = 1.6 + 0.05 = 1.65.

For an upper-tailed test, the critical value is given by;

Z_{critical} = 1.65.

Therefore, if Z_{test} > 1.65; reject null hypothesis (H₀) and if Z_{test} < 1.65; fail to reject null hypothesis (H₀).

Next, we would determine the test statistic:

[tex]Z_{test} = \frac{116 -121 -0}{\sqrt{\frac{16^2}{50} +\frac{16^2}{50} } } \\\\Z_{test} = \frac{-5}{\sqrt{\frac{256}{50} +\frac{256}{50} } }\\\\Z_{test} = \frac{-5}{\sqrt{10.24} }[/tex]

Z_{test} = -5/3.2

Z_{test} = -1.5625

In conclusion, we would fail to reject null hypothesis (H₀) since a Z_{test} of -1.5625 is less than a Z_{critical} of 1.65.

Answer:

Step-by-step explanation:

The surface area of a sphere is given by the formula:

S = 4πr^2

where S is the surface area and r is the radius of the sphere.

We are given that the surface area of the sphere is 60 square feet. Using the formula above, we can solve for the radius:

60 = 4πr^2

Dividing both sides by 4π, we get:

15/π = r^2

Taking the square root of both sides, we get:

r = sqrt(15/π)

Using 3.14 as an approximation for π, we can evaluate this expression:

r ≈ sqrt(15/3.14)

r ≈ 2.20

Therefore, the best approximation for the radius of the sphere is 2.20 feet.

The interest earned by the $300 savings account is $90, and the total balance at the end of 5 years is $390.

A check register balance is the amount of money in a bank account, as recorded by the account holder in their check register, after accounting for deposits, withdrawals, and fees.

1)

The check register balance is not correct. To find the correct balance, we need to adjust the statement ending balance for the outstanding deposits, subtract the outstanding check and service charge, and add any other transactions that may have been missed.

Adjusted balance for outstanding deposits: $41.27 + $27.70 + $12.30 + $102.43 = $183.70

Adjusted balance for outstanding deposits minus the outstanding check: $183.70 - $10.98 = $172.72

Adjusted balance for outstanding deposits minus the outstanding check minus the service charge: $172.72 - $5.82 = $166.90

Therefore, the correct check register balance is $166.90.

2)
To find the balance of the savings account after various time periods, we can use the formula for compound interest:

A = P(1 + r/n)^(nt)

Where:

A = the balance after time t

P = the principal (initial deposit)

r = the annual interest rate (as a decimal)

n = the number of times the interest is compounded per year

t = the time period (in years)

For this problem, we have:

P = $500

r = 0.04

n = 4 (compounded quarterly)

t = 0.25 (3 months), 0.5 (6 months), 0.75 (9 months), 1 (1 year)

After 3 months:

A = $500(1 + 0.04/4)^(4*0.25) = $510.08

After 6 months:

A = $500(1 + 0.04/4)^(4*0.5) = $520.40

After 9 months:

A = $500(1 + 0.04/4)^(4*0.75) = $531.07

After 1 year:

A = $500(1 + 0.04/4)^(4*1) = $542.50

Therefore, the balance of the savings account after 3 months is $510.08, after 6 months is $520.40, after 9 months is $531.07, and after 1 year is $542.50.


3)
To find the interest earned and total balance at the end of each year, we can use the formula for compound interest:

A = P(1 + r/n)^(nt)

Where:

A = the balance after time t

P = the principal (initial deposit)

r = the annual interest rate (as a decimal)

n = the number of times the interest is compounded per year

t = the time period (in years)

For this problem, we have:

P = $1000

r = 0.08

n = 1 (compounded annually)

t = 1 (year)

After year 1:

Interest earned = $1000 x 0.08 = $80

Total balance = $1000 + $80 = $1080

After year 2:

Interest earned = $1080 x 0.08 = $86.40

Total balance = $1080 + $86.40 = $1166.40

After year 3:

Interest earned = $1166.40 x 0.08 = $93.31

Total balance = $1166.40 + $93.31 = $1259.71

Therefore, the interest earned in year 1 is $80, the total balance at the end of year 1 is $1080, the interest earned in year 2 is $86.40, the total balance at the end of year 2 is $1166.40, and the interest earned in year 3 is $93.31, and the total balance at the end of year 3 is $1259.71.

4)

We can use the formula for compound interest to calculate the interest earned and total balance at the end of each year for each savings account:

$100 at 7% for 4 years:

P = $100, r = 0.07, n = 1 (compounded annually), t = 4

Interest earned = $100 x 0.07 x 4 = $28

Total balance = $100 + $28 = $128 after 4 years

$500 at 8% for 3 years:

P = $500, r = 0.08, n = 1 (compounded annually), t = 3

Interest earned = $500 x 0.08 x 3 = $120

Total balance = $500 + $120 = $620 after 3 years

$300 at 6% for 5 years:

P = $300, r = 0.06, n = 1 (compounded annually), t = 5

Interest earned = $300 x 0.06 x 5 = $90

Total balance = $300 + $90 = $390 after 5 years

Therefore, the interest earned by the $100 savings account is $28, and the total balance at the end of 4 years is $128.
The interest earned by the $500 savings account is $120, and the total balance at the end of 3 years is $620.
The interest earned by the $300 savings account is $90, and the total balance at the end of 5 years is $390.

Using a trigonometric relation, we can see that the values of x and y are:

y = 25.98

x = 15

Here we can see a right triangle, where we know the interior angles and the length of the hypotenuse.

To get the lengths of the legs, we can use trigonometric relations, like:

cos(a) =(adjacent cathetus)/hypotenuse.

For example, if we want to find y, then the angle at which this side is adjacent is the 30° one, now replacing the known values in the formula we will get:

cos(30°) = y/30

cos(30°)*30 = y = 25.98

And to get the value of x, we should use the 60°angle, so:

cos(60°) = x/30

30*cos(60°) = x =  15

These are the two lengths we wanted to get.

The formula for the future value of an annuity is FV = Pmt * (((1 + r)n - 1) / r) to calculate the balance of the IRA at age 65. To compare this amount to the total deposits made over the time period, Total Deposits = Pmt * n = $45,600.

To calculate the balance of the IRA at age 65, we need to use the formula for the future value of an annuity:

FV = Pmt * (([tex](1 + r)^n[/tex] - 1) / r)

Where:

Pmt = $95 (the monthly deposit amount)

r = 4% / 12 = 0.003333 (the monthly interest rate)

n = (65 - 25) * 12 = 480 (the total number of months, assuming retirement at age 65)

Plugging in these values, we get:

FV = 95 * (([tex](1 + 0.003333)^480[/tex] - 1) / 0.003333)

FV = $98,052.52

Therefore, the IRA will contain $98,052.52 at age 65.

Part 2

To compare this amount to the total deposits made over the time period, we can calculate the total deposits as:

Total Deposits = Pmt * n

Plugging in the values, we get:

Total Deposits = 95 * 480

Total Deposits = $45,600

Therefore, the IRA will contain significantly more than the total deposits made over the time period, due to the power of compounding interest.
