There is approximately an 89.44% probability that a box of cereal is underfilled by 5 g or more.

To find the probability that a box of cereal is underfilled by 5 g or more, we need to calculate the probability of obtaining a weight measurement below 345 g.

First, we can standardize the problem by using the z-score formula:

z = (x - μ) / σ

Where:

x = the weight value we want to find the probability for (345 g in this case)

μ = the mean weight (350 g)

σ = the standard deviation (4 g)

Substituting the values into the formula:

z = (345 - 350) / 4 = -1.25

Next, we can find the probability associated with this z-score using a standard normal distribution table or a statistical calculator.

The probability of obtaining a z-score less than -1.25 is approximately 0.1056.

However, we are interested in the probability of underfilling by 5 g or more, which means we need to find the complement of this probability.

The probability of underfilling by 5 g or more is 1 - 0.1056 = 0.8944, or approximately 89.44%.

Therefore, there is approximately an 89.44% probability that a box of cereal is underfilled by 5 g or more.

Answer:A school bus provides a safe way of transportation for your child. Learn resources to talk to your child about school bus and bus stop safety.

Step-by-step explanation:

Calista's grade on her last assignment is 98.

To determine Calista's grade on her last assignment, we can calculate the average grade using the given information.

The sum of Calista's grades on the first five assignments is: 62 + 88 + 92 + 74 + 78 = 394.

Since the average grade is given as 82, we can find the total sum of all six assignments by multiplying the average grade by the number of assignments, which is 6: 82 * 6 = 492.

To find Calista's grade on her last assignment, we subtract the sum of her grades on the first five assignments from the total sum: 492 - 394 = 98.

Question:

The relationship between t and r is expressed by the equation 2t+3r+6 = 0. If r increases by 4, which of the following statements about t must be true?

Answer:

The value of t is reduced by 6 when the value of r is increased by 4

Step-by-step explanation:

Given

\(2t + 3r + 6 = 0\)

Required

What happens when r is increased by 4

\(2t + 3r + 6 = 0\) -------- Equation 1

Subtract 2t from both sides

\(2t + 3r + 6 - 2t = 0 - 2t\)

\(3r + 6 = - 2t\) --- Equation 2

When r is increased by 4, equation 1 becomes

\(2T + 3(r+4) + 6 = 0\)

Note that the increment of r also affects the value of t; hence, the new value of t is represented by T

Open bracket

\(2T + 3r+12 + 6 = 0\)

Rearrange

\(2T + 3r+6 +12 = 0\)

Substitutr -2t for 3r + 6 [From equation 2]

\(2T -2t +12 = 0\)

Make T the subject of formula

\(2T = 2t - 12\)

Divide both sides by 2

\(\frac{2T}{2} = \frac{2t - 12}{2}\)

\(T = t - 6\)

This means that the value of t is reduced by 6 when the value of r is increased by 4

The side b is approximately 80.02 feet in length. In a right triangle ABC with angle C equal to 90°, if angle B is 37.56° and side a is 49.94 feet, we can solve for side b using the trigonometric function sine.

First, we can label the triangle as follows:

Side a is opposite angle A,

Side b is opposite angle B,

Side c is the hypotenuse.

Let's label the triangle with the given and asked for information. Angle C is the right angle, angle B is 37.56°, side a is 49.94 feet, and side b is the side we are trying to find.

Using the sine function, we have:

sin(B) = opposite/hypotenuse

sin(37.56°) = a/b

Now we can substitute the known values:

sin(37.56°) = 49.94/b

To solve for b, we rearrange the equation:

b = 49.94 / sin(37.56°)

Using a calculator, we find:

b ≈ 80.02 feet.

Answer:

h = 452.5 ft

Step-by-step explanation:

Angle of elevation from P to top of the pole = 65°

Horizontal distance between the pole and point P = 21 ft

By Applying tan rule in the given triangle ABP,

tan(∠APB) = \(\frac{AB}{PB}\)

tan(65°) = \(\frac{h}{21}\)

h = 21[tan(65°)]

h = 452.491

h ≈ 452.5 ft

Therefore, height of the pole is 452.5 ft.

About 88.49% of cellphone plans have charges that are less than $83.60.

To determine the percentage of plans that have charges less than $83.60, we need to find the z-score (z) using the given mean and standard deviation, and then look up the corresponding area under the normal distribution curve.

z = (x – μ) / σ

where x = 83.60, mean, μ =  62 and standard deviation, σ = 18

Thus, the z-score of $83.60 is:

z = (83.60 - 62) / 18 = 1.2

Using a standard normal distribution table, we can find that the area to the left of z = 1.20 is 0.8849 or 88.49% (check image attached).

Therefore, about 88.49% of cellphone plans have charges that are less than $83.60.

Answer : The average rate of change between 1 year and 4 years  of age is 7.33 lbs per year.

Step-by-step explanation :

As we know that the average rate of change between two input values is the total change of the output values divided by the change in the input values.

From the table, we conclude that:

The weight of 1 year of age = 20 lbs

The weight of 4 years of age = 42 lbs

Now we have to determine the average rate of change between 1 year and 4 years  of age.

The input (years) has changed by = 4 years - 1 year = 3 years

The output has changed by = 42 lbs - 20 lbs = 22 lbs

Average rate of change = Output ÷ Input

Average rate of change = \(\frac{22\text{ lbs}}{3\text{ years}}\)

Average rate of change = 7.33 lbs per year

Therefore, the average rate of change between 1 year and 4 years  of age is 7.33 lbs per year.

The values of x in the absolute value function 5 - 9|4 - 8x| = -103 are (b) {-1, 2}

From the question, we have the following parameters that can be used in our computation:

5 - 9|4 - 8x| = -103

Subtract 5 from both sides of the equation

so, we have the following representation

- 9|4 - 8x| = -108

Divide both sides by -9

|4 - 8x| = 12

Remove the absolute bracket

Thisgives

4 - 8x = 12 or 4 - 8x = -12

So, we have

-8x = 8 or -8x = -16

x = -1 or x = 2
