Answer:

D: ∛(¼(x + 5))

Step-by-step explanation:

The parent function is;

f(x) = ∛x

A horizontal stretch multiplying by ¼ means that our function is now;

f(x/4) = ∛(x/4)

Now shifting to the left by 5 units denotes;

f(x + 5) = ∛((x + 5)/4)

Or expressed as; ∛(¼(x + 5))

Step-by-step explanation: To start off, note that 4 1/4 is a mixed number, also known as a mixed fraction. It has a whole number and a fractional number. We have labeled the parts of the mixed number below so it is easier to follow along.

4 = Whole number

1 = Numerator

4 = Denominator

To get 4 1/4 in decimal form, we basically convert the mixed number to a fraction and then we divide the numerator of the fraction by the denominator of the fraction.

Here are the detailed math steps we use to convert 4 1/4 mixed number to decimal form:

Step 1: Multiply the whole number by the denominator:

4 × 4 = 16

Step 2: Add the product you got in Step 1 to the numerator:

16 + 1 = 17

Step 3: Divide the sum from Step 2 by the denominator:

17 ÷ 4 = 4.25

That's it folks! The answer to 4 1/4 in decimal form is displayed below:

4 1/4 = 4.25

Step-by-step explanation:

First of all find the area of the rectangle

L*W

15*30

450

Now find the area of semi circle

1/2[tex]\pi r^{2}[/tex]

Since radius is half a diameter divided 15 by 2=7.5

1/2[tex]\pi 7.5^{2}[/tex]                            7.5 times 7.5= 56.25

1/2*3.14*56.25

56 times 3.14 is 176.625 now multiply 176.625 by 1/2

Answer is 88.3125

Now add 450 to 88.3125

Final answer: 538.3125

Answer:

-60

Step-by-step explanation:

Given the expression

5- {2*[(-5power2) -7 ] /3}

= 5- {2*[(25) -7 ] /3}

= 5- {2*[18 ] /3}

= -5 [2*6]

= -5(12)

= -60

Hence the required answer is -60

Answer:

C. 139 ft

Step-by-step explanation:

Height of the pole = x + 4 ft

First, find x using trigonometric function.

Reference angle = 44°

Opposite side length = x

Adjacent side length = 140 ft

Apply TOA, which is:

Tan 44 = opp/adj

Tan 44 = x/140

Multiply both sides by 140

140 × Tan 44 = x

135.196428 = x

x ≈ 135 ft

✔️Height of the pole = x + 4 ft = 135 + 4 = 139 ft

Complete question :

A business owner wants to know if it will be profitable to open a new coffee shop in a nearby town.In towns where the shop has been successful,the shop name is recognizable to people 53% of the time .He survey random sample of 12 residents of the town.  Find the probability that among these 12 surveyed residents, none of them have ever heard of the coffee shop

Answer:

0.000116

Step-by-step explanation:

Using the binomial probability relation :

Probability of success, p = 0.53

1 - p = 0.47

Number surveyed, n = 12

P(x =x) = nCx  * p^x * (1 - p)^(n - x)

Probability that none has heard of the coffee shop :

P(x = 0) = 12C0 * 0.53^0 * 0.47^12

P(x = 0) = 0.000116

(5x + 15)⁰+ (3x - 3⁰) = 180⁰ ( same side on interior angle theorm)

(8x + 12)⁰= 180⁰

8x = 168⁰

x = 21

Angle 1 +( 3x - 3)⁰ = 180⁰⁰ ( linear pair)

Angle 1 + 63 - 3⁰ = 180⁰

Angle 1 + 60⁰ = 90⁰

Angle 1 = 180⁰- 60⁰

Angle 1 = 120⁰

Answer:

(5x+15)°+(3x-3)°=180°(by co interior angle)

5x+3x+15 - 3=180°

8x+12=180°

8x=180°-12

8x=168°

x=168/8

x=21

by putting value of x

(3x-3)° = 3×21-3 = 60°

60°+angle 1 = 180°[by linear pair]

angle 1=180°-60°

angle 1=120°

D. the standard error of the mean

Step-by-step explanation:

trust me i got it right Plato

The value needed to determine a confidence interval for a sample mean is the standard error of the mean option (D) is correct.

It is defined as the sampling distribution following an approximately normal distribution for known standard deviation.

The formula for finding the confidence interval for population standard deviation as follows:

[tex]\rm s\sqrt{\dfrac{n-1}{\chi^2_{\alpha/2, \ n-1}}} < \sigma < s\sqrt{\dfrac{n-1}{\chi^2_{1-\alpha/2, \ n-1}}}[/tex]

Where s is the standard deviation.

n is the sample size.

[tex]\chi^2_{\alpha/2, \ n-1} and \chi^2_{1-\alpha/2, \ n-1}[/tex] are the constant based on the Chi-Square distribution table:

α is the significance level.

σ is the confidence interval for population standard deviation.

Calculating the confidence interval for population standard deviation:

We know significance level = 1 - confidence level

It is given that:

The value needed to determine a confidence interval for a sample mean is the standard error of the mean.

CI = X + Z(s/√n)

Here CI is the confidence interval

Z is the confidence level

X is the sample mean

Thus, the value needed to determine a confidence interval for a sample mean is the standard error of the mean option (D) is correct.

Step-by-step explanation:

The general form of the quadratic equation is :

[tex]ax^2+bx+c[/tex]

The given equation is x²+4x+20=0

On comparing the given equation and the general equation, we find that

a = 1, b = 4 and c = 20

Hence, the correct option is a=1 b =4 c = 20.

If the equation is 2x²+6x+5=0, then

a = 2, b = 6 and c = 5

If the equation is -2x²+x+5

a = -2, b = 1 and c = 5
