Answer:

  (d)  27.4%

Step-by-step explanation:

The desired percentage is ...

  (juniors for Kato)/(total juniors) × 100%

  =  129/(129 +194 +147) × 100%

  = (129/470) × 100% ≈ 27.4%

About 27.4% of juniors voted for Kato.

Insured = 72%.

Uninsured = 28%.

A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.

Given:

Here is a table classifying 116 thousand US households (in thousands) in

2013 by tenure and insurance status:

Insurance status      Owns home   Rents home

Insured                              71                13

Uninsured                         27               5

Total house = 71 + 13 + 5 + 27 = 116

Insured = (71 + 13)/116 = 72%.

Uninsured = (5 + 27)/116 = 28%.

Therefore, 72% = insured and 28% = uninsured.

The value of the resistor needed in this scenario is approximately 1.2 ohms.

To find the value of the resistor in the given scenario, we can apply Ohm's Law, which states that the current (I) flowing through a resistor is directly proportional to the voltage (V) across it, and inversely proportional to the resistance (R) of the resistor.

Using Ohm's Law, we have the formula:

V = I * R

Where:

V is the voltage across the resistor (12 volts in this case),

I is the current flowing through the resistor (5 amps for each light, so a total of 10 amps),

R is the resistance of the resistor (which we need to find).

Rearranging the formula, we have:

R = V / I

Plugging in the values:

R = 12 volts / 10 amps

R = 1.2 ohms

Therefore, the value of the resistor needed in this scenario is approximately 1.2 ohms.

It's worth noting that this calculation assumes the lights are connected in parallel, as the current remains the same for each light. If the lights were connected in series, the total resistance would be the sum of the individual resistances, and the calculation would be different.

The persons weight that had the least absolute change is: Rebecca

We are given the initial and final weights of Ophelia, Aaron, Nathan and Rebecca.

Ophelia's change in weight = 157 - 145 = 12 lbs

Aaron's change in weight = 163 - 178 = -15 lbs

Nathan's change in weight = 217 - 136 = 81 lbs

Rebecca's change in weight = 128 - 136 = -8 lbs

The absolute value of a number or integer is the actual distance of the integer from zero, in a number line. Therefore, the absolute value is always a positive .

Thus, "absolute value" means to remove any negative sign in front of a number, and to think of all numbers as positive (or zero).

Therefore, the least absolute change is |-8 lbs| = 8 lbs

Answer:

6.2cm

Step-by-step explanation:

I plotted values in the equation to get the rightful answer.

The approximate radius of the sphere with volume of 998 cm³ is 6.2 cm

Volume of a sphere:

where

r = radius

V = 998 cm³

π = 3.14

V = 4 / 3  × 3.14 × r³

V = 12.56 r³ / 3

998 = 12.56 r³ / 3

cross multiply

998 × 3  = 12.56r³

2994 = 12.56r³

divide both sides by 12.56

r³ = 2994 / 12.56

r = ∛238.375796178

r = 6.20041444

The probability that it is not yellow candies will be 119/139.

What is mean by Probability?

The term probability refers to the likelihood of an event occurring.

Given that;

A bag contains;

Number of red candies = 42

Number of green candies = 45

Number of yellow candies = 20

Number of purple candies = 32

Now,

Total number of candies in a bag = 42 + 45 + 20 + 32

                                                   = 139

And, The number of candies in a bag not contain yellow candy

= 139 - 20

= 119

Thus, The probability that it is not yellow candies will be;

Probability = Number of not yellow candies / Total candies

                = 109 / 139

Therefore, The probability that it is not yellow candies will be 119/139.

In football quarterback, a total gain of 11 yards was per pass.

Here we have been given that the football quarterback completed 17 passes for a total gain of 194 yards. This can be numerically stated as,

                                17 passes = 194 yards

We have been asked the number of yards gained in unit pass, that is,

                              1 pass = x yards

                                                   Where x = number of yards

Now by using unitary method we will get the average number of yards gained 1 per pass.

Therefore combining the equation (1) and (2) and solving them we will get,

                        17 pass = 194

                        1 pass = 194/17 yards

                                    =  11.4 ≈ 11 yards

Thus, 11 yards were gained per pass.

Answer:

The given data does not support the submission that there has been a change in the mean arrival times on Southwest

Step-by-step explanation:

The known mean late arrival time, μ = 72.3

The known standard deviation in late arrival time, σ = 9.8 minutes

The number of flights in the sample, n = 47

The sample mean late arrival time, \(\overline x\) = 70.7

The sample standard deviation  late arrival time, s = 7.1

Using a significance level of 0.01

The null hypothesis is, H₀ ; μ = 70.7

The alternative hypothesis is, Hₐ ; μ ≠ 70.7

The test statistic is given as follows;

\(z=\dfrac{\bar{x}-\mu }{\dfrac{\sigma }{\sqrt{n}}}\)

\(z=\dfrac{70.7-72.3 }{\dfrac{9.8 }{\sqrt{47}}} \approx -1.119290547\)

∴ z ≈ -1.12

p-value = 2 × P(z < -1.12)  = 2 × 0.13136 = 0.26272

Given that the p-value of 0.26272 is larger than the significance level, 0.05, we fail to reject the null hypothesis

Therefore, there is not enough statistical evidence to show that there has been a change in the mean arrival times on Southwest

Answer:

\(\boxed {\tt 36 \ centimeters}\)

Step-by-step explanation:

The perimeter is the sum of all the side lengths and a square has 4 equal sides.

The perimeter of a square can be found by adding the side length 4 times or multiplying the side length by 4.

\(p=4s\)

The side length is 9 centimeters.

\(s= 9 \ cm\)

Substitute the value into the formula.

\(p=4(9 \ cm)\)

Multiply

\(p= 36 \ cm\)

The perimeter of a square with a side length of 9 centimeter is 36 centimeters.

The solution of the system of linear equations is (x, y, z) = (1, 1, - 3).

In this problem we find a system of three linear equations with three variables, which can be resolved by several methods. In this case, we shall use the method of substitution. First, clear the variable x in the third equation:

x = 4 - 3 · y

Second, substitute x in the first two equations:

3 · (4 - 3 · y) + 2 · y - z = 8

12 - 9 · y + 2 · y - z = 8

- 7 · y - z = - 4

2 · (4 - 3 · y) + 2 · z = - 4

8 - 6 · y + 2 · z = - 4

- 6 · y + 2 · z = - 12

Third, clear z in the first equation derived in the previous step:

z = 4 - 7 · y

Fourth, substitute z in the second equation derived in the second step:

- 6 · y + 2 · (4 - 7 · y) = - 12

- 6 · y + 8 - 14 · y = - 12

- 20 · y = - 20

y = 1

Fifth, calculate y and x:

z = 4 - 7 · 1

z = - 3

x = 4 - 3 · 1

x = 1

The solution of the system of linear equations is (x, y, z) = (1, 1, - 3).

Step-by-step explanation:

Let X be a random variable that represents percent of fat calories that a person in America consumes each day.

As per given , X is normally distributed with a mean \(\mu=36\) and a standard deviation \(\sigma=10\).

Sample size : n= 16

The probability that the average percent of fat calories consumed is more than 35:

\(P(\overline{X}>35)=P(\dfrac{\overline{X}-\mu}{\dfrac{\sigma}{\sqrt{n}}}>\dfrac{35-36}{\dfrac{10}{\sqrt{16}}})\\\\=P(Z>\dfrac{-1}{\dfrac{10}{4}})\ \ \ [Z=\dfrac{\overline{X}-\mu}{\dfrac{\sigma}{\sqrt{n}}}]\\\\=P(Z>\dfrac{-4}{10})\\\\=P(Z>-0.4)\\\\=P(Z<0.4)\ \ \ [P(Z>-z)=P(Z<z)]\\\\=0.655\ \ \ [\text{By p-value table}]\)

The local maxima and local minima for the given function is x= 3 and

x= 1.

Here,

\(f(x) = x^{3} -6x^{2} +9x +15 = 0\\f(x) = 3x^{2} -12x +9\)

In order to have local maxima and minima, f′(x) must equal 0.

\(f(x) =0 = > 3(x^{2} -4x+3)=0\\=3(x-3)(x-1) = 0\\ x=3,x=1\)

1) When x = 3

In this instance, f′(x) = 3(x-3)9x-1) is negative when x is little less than 3 and positive when x is slightly more than 3.

Hence, when x rises through 3, f′(x) turns from negative to positive.

Hence, x=3 is a local minimum.

Case 2, x = 1,

In this instance, f′(x) = 3(x-3) (x-1) is positive when x is little less than 1 and f′(x) is negative when x is slightly greater than 1. As x rises through 1, f′(x) sign's shifts from positive to negative.

Hence, x=1 is a local maximum point.
