At a local restaurant, the amount of time that customers have to wait for their food is normally distributed with a mean of 26 minutes and a standard deviation of 4 minutes. Using the empirical rule, determine the interval of minutes that the middle 95% of customers have to wait.

Answers

Answer 1

The middle 95% of customers have to wait for 18 to 34 minutes at the resturant.

What is the empirical rule?

The empirical rule states that for a normal distribution. 68% of the values are within one standard deviation from the mean, 95% of the values are within two standard deviation from the mean and 99.7% of the values are within three standard deviation from the mean

Given a mean of 26 minutes and a standard deviation of 4 minutes. Hence:

95% are within 2 standard deviations = 26 ± 2(4) = (18, 34)

The middle 95% of customers have to wait for 18 to 34 minutes at the resturant.

What is the value of a if 3(a − 5) = 2(a +5)?

Answers

Answer:

a= 25

Step-by-step explanation:

STEPS FOR SOLVING LINEAR EQUATION

3(a−5)=2(a+5)

Use the distributive property to multiply 3 by a−5.

3a−15=2(a+5)

Use the distributive property to multiply 2 by a+5.

3a−15=2a+10

Subtract 2a from both sides.

3a−15−2a=10

Combine 3a and −2a to get a.

a−15=10

Add 15 to both sides.

a=10+15

Add 10 and 15 to get 25.

a=25

What number increased by ¼ of itself is equal to 30?

Answers

Answer:

x = 24

Step-by-step explanation:

let x be the number we want to determine its value

The statement  x increased by ¼ of itself is equal to 30

is equivalent to :

[tex]x + \frac{x}{4}=30\\\\then[/tex]

[tex]\frac{4x+x}{4} = 30\\\\then[/tex]

[tex]\frac{5x}{4} = 30\\\\then[/tex]

5x = 4× 30

then

5x = 120

then

x = 120/5

then

x = 24

Graph the function f(x) = x3 – 4x – 1. Which are approximate solutions for x when f(x) = 0? Select three options.

–2.11
–1.86
–0.25
0.25
2.11

Answers

The approximate solutions for x when f(x) = 0 are -0.25, -1.86, and 2.11.
The given function is:
f(x)=x^3-4x-1
What is the solution to an equation?
The solution to an equation is the point where the function value becomes zero.
As we know when f(a).f(b) <0, the root lies in between a and b.
f(-1) = 2
f(0) = -1
f(-1).f(0) = -2
So a solution will lie in between (-1,0).
Similarly,
f(-3) = -ve
f(-2)= -ve
No solution in between -3 and -2
f(-2) = -ve
f(-1) = +ve
One solution in between -2 and -1 i.e. -1.86
f(0) = -ve
f(1) = -ve
No solution in between 0 and 1
f(1) = -ve
f(2) = -ve
No solution in between 1 and 2.
f(2) = -ve
f(3) = +ve
One solution in between 2 and 3 i.e. 2.11
Therefore, the approximate solutions for x are -0.25, -1.86, and 2.11.

The roots of the polynomial will be -1.86, -0.25, and 2.11. Then the correct options are B, C, and E.

What is the solution of the polynomial?

Let a, b, c, and d be the zeroes of the polynomial and k be the leading coefficient.

Then the polynomial is given as,

⇒ k(x - a)(x - b)(x - c)(x - d)

The degree of the polynomial will be greater than or equal to the number of zeroes.

The zeroes of the polynomial are the intersection points of the curve with the x-axis.

The graph of the polynomial is drawn below.

From the graph, the roots of the polynomial will be -1.86, -0.25, and 2.11. Then the correct options are B, C, and E.

What is the explicit formula for this geometric sequence?

8, 4, 2, 1, …


Answers

Answer:

[tex]a_{n} = \frac{8}{2^{n-1} }[/tex]

Step-by-step explanation:

A geometric sequence has a constant ratio (r) and is defined by:

[tex]a_n=a_1r^{n-1}[/tex]

Since the first value is 8, [tex]a_{1}[/tex] = 8.

[tex]a_n=8r^{n-1}[/tex]

We can also see that a_n is double that of the next value in the sequence [tex](a_{n} = 2a_{n+1}})[/tex], hence r = 1/2

[tex]a_n=8\left(\frac{1}{2}\right)^{n-1}[/tex]   or

[tex]a_{n} = \frac{8}{2^{n-1} }[/tex]

Upon review of production results, it was determined that 130 pieces out of 3,500 were "out of spec." What percent of the production was "out of spec"?

A. 0.03 percent .
B. 3.71 percent .
C. 30 percent
D. 37.1 percent

Answers

Answer:

Option B

Step-by-step explanation:

Given:

130 pieces of 3500 were out of spec

To determine the percentage of the production was out of spec, we need to use the percentage formula (x/y × 100).

[tex]\implies \dfrac{x}{y} \times 100[/tex]

The value of "x" is the the number of pieces that were out of spec and the value of "y" is the total pieces in the production results.

[tex]\implies \dfrac{130}{3500} \times 100[/tex]

Simplify the expression to determine the percentage of the pieces that were out of spec.

[tex]\implies \dfrac{13000}{3500}[/tex]

[tex]\implies \dfrac{130}{35} = \dfrac{130 \div 5}{35 \div 5} = \dfrac{26}{7} = 3.714... \%[/tex]

When the percentage is estimated to nearest hundredth, we get 3.71%

(Option B)

Answer:

B)  3.71%

Step-by-step explanation:

[tex]\textsf{130 out of 3500}\sf =\dfrac{130}{3500}[/tex]

To convert to a percentage, multiply by 100:

[tex]\implies \sf \dfrac{130}{3500} \times 100\%=0.03714.. \times 100\%=3.71\%[/tex]
