The probability that a randomly selected bag contains fewer than 1050 chocolate​ chips is 0.84.

(a) The probability of a randomly selected bag containing between 1000 and 1400 chips is 0.75.

This is calculated using the standard normal distribution formula:

P(1000 < X < 1400)

= P(z < (1400-1252)/129) - P(z < (1000-1252)/129)

= 0.75

(b) The probability of a randomly selected bag containing fewer than 1050 chips is 0.26.

This is calculated using the standard normal distribution formula:

P(X < 1050) = P(z < (1050-1252)/129)

= 0.26

(c) The proportion of bags containing more than 1175 chips is 0.84.

This is calculated using the standard normal distribution formula:

P(X > 1175) = P(z > (1175-1252)/129)

= 0.84

(d) The percentile rank of a bag containing 1050 chips is 26%.

This is calculated using the standard normal distribution formula:

P(X < 1050) = P(z < (1050-1252)/129)

= 0.26

Therefore, the probability that a randomly selected bag contains fewer than 1050 chocolate​ chips is 0.84.

Answer:

6.4

Step-by-step explanation:

First add 10 to 22 to get 32

Then divide 32 by 5 to get x

The total number of people in attendance was 400 people in total.

Let:

x be the no of grandparents

y be the no of parents

z be the no of children

Since there are 400 people total, so we can write the equation:

x + y + z = 400

We also know that there were twice as many parents as grandparents, so we can write the equation:

y = 2x

We know that there were 50 more children than parents, so we can write the equation:

z = y + 50

Now we have a system of three equations with three variables:

x + y + z = 400

y = 2x

z = y + 50

We can solve this system using substitution method

First, we can use the second equation to express y in terms of x:

y = 2x

Next, we can use the third equation to express z in terms of x:

z = y + 50

z = 2x + 50

Now we can substitute these expressions for y and z into the first equation:

x + y + z = 400

x + (2x) + (2x + 50) = 400

5x + 50 = 400

5x = 350

x = 70

So there were 70 grandparents in attendance.

Using the second equation, we can find the number of parents:

y = 2x

y = 2(70)

y = 140

So there were 140 parents in attendance.

Using the third equation, we can find the number of children:

z = y + 50

z = 140 + 50

z = 190

So there were 190 children in attendance.

Therefore, the total number of people in attendance was:

70 grandparents + 140 parents + 190 children = 400 people in total.

The fish population in Lake Collins is estimated to be about 938 fish in 2009.

Given that:

Rate, r = 4%

Let P(x) be the population of fish in Lake Collins after x years, where x is measured from 2004. Since the fish population is decreasing at a rate of 4% per year, we can write:

P(x) = 1,150 (0.96)ˣ

To find the population in 2009 (which is 5 years after 2004), we substitute x = 5 into the equation:

P(5) = 1,150 * (0.96)⁵

P(5) = 1,150 * 0.8154

P(5) = 937.8 or 938

Therefore, the fish population in Lake Collins is estimated to be about 938 fish in 2009.

The function for this problem is defined as follows:

f(x) = 14/[3 + ae^(kx)]

When x = 0, y = 2, hence we can obtain the coefficient a as follows:

2 = 14/(3 + a)

6 + a = 14

a = 8.

Hence:

f(x) = 14/[3 + 8e^(kx)]

When x = 1, y = 1/2, hence the coefficient k is given as follows:

0.5 = 14/(3 + 8e^k)

4e^k = 12.5

e^k = 12.5/4

k = ln(12.5/4)

k = 1.14.

The surface area of the triangular prism is 191 cm².

The surface area (SA) of a triangular prism is given by the formula:

SA = 2A + Ph

where A is the area of the base, P is the perimeter of the base, and h is the height of the prism.

First, we need to find the area of the triangular base.

Using the formula for the area of a triangle:

A = (1/2)bh = (1/2)(5 cm)(4 cm) = 10 square centimeter

Next, we need to find the perimeter of the base:

P = 5 cm + 6 cm + 8 cm = 19 cm

Now we can use the formula for the surface area of a triangular prism:

SA = 2A + Ph

= 2(10 cm²) + (19 cm)(9 cm)

= 20 cm²+ 171 cm²

= 191 cm²
