Answer 1

Answer:

885.2m²

Step-by-step explanation:

a is the side length of the square at the base

h is the height of the pyramid

Given

a = 18m

Get the height using the pythagoras theorem

h² =18²-9²

h² = 324 - 81

h² = 243

h = √243

h = 15.5884m

Area of the triangle = 1/2 * 18 * 15.5884

Area of the triangle = 9 * 15.5884

Area of the triangle = 140.2956m²

Area of the 4 triangles = 4(140.2956)

Area of the 4 triangles = 561.1824m²

Base area = 18 * 18

Base area = 324m²

Total surface area = Base area + Area of the 4 triangles

Total surface area = 324 + 561.1824

Total surface area = 885.1824

Total surface area = 885.2m² (to the nearest tenth)

peaches are on sale for 0.95 cents per pounds if i have 2.75 pounds how much did i pay for the peaches?

(Please help im horrible at this)

Answers

Answer:

$2.61

Step-by-step explanation:

I think you mean 0.95 dollars per pound. 0.95 cents means it's less than a dime per pound.

Answer: $2.62

Step-by-step explanation:

Rate: 0.95 = 1 pound The equation: ? = 2.75

1) First divide 2.75 and 1 to find the multiplicative so you can multiply this number to 0.95.

2.75 ÷ 1 = 2.75

2) Multiply 2.75 by 0.95.

2.75 x 0.95 = 2.6125

3) Round the number(?)

2.6125 = 2.62

Step-by-step explanation:

A football team needs to have at least 11 players. Only 4 people have signed up to play on

the Flying Squirrels football team so far.

Let x represent how many more people need to sign up. Which inequality describes the

problem?

4 + x 2 11

4 + x > 11

Solve the inequality. Then, complete the sentence to describe the solution.

At least

more people need to sign up.

Submit

Work it out

Not feeling ready yet? This can help:

Answers

Answer:

x ≥ 7

At least 7 more people need to sign up.

Step-by-step explanation:

We need to have at least 11, so the number of players needs to be greater or equal to 11. So, the equation is:

4 + x ≥ 11

To solve, subtract 4 from both sides.

x ≥ 7

At least 7 more people need to sign up.

The inequality which represents the situation is 4 + x ≥ 11 and the phrase will be at least 7 more people need to sign up.

What is inequality?

A difference between two values indicates whether one is smaller, larger, or basically not similar to the other.

In other words, inequality is just the opposite of equality for example 2 =2 then it is equal but if I say 3 =6 then it is wrong the correct expression is 3 < 6.

As per the given,

A football team needs to have at least 11 players. Only 4 people have signed up.

Let's say x number of people need to have at least 11.

x + 4 ≥ 11

x ≥ 11 - 4 = 7

Thus, at least 7 people more required.

Hence "The inequality which represents the situation is 4 + x ≥ 11 and the phrase will be at least 7 more people need to sign up".

that can be used to find how many pages Kat read.

Answers

Answer:

Step-by-step explanation:

Let Kat reads k pages of the book.

Miguel reads 5 times as many  pages of the book as Kat. So,

The amount of time all students in a very large undergraduate statistics course take to complete an examination is distributed continuously and normally. The probability a student selected at random takes at least 55.50 minutes to complete the examination equals 0.6915. The probability a student selected at random takes no more than 71.52 minutes to complete the examination equals 0.8997.
a) Determine the value for the mean (u) of the associated distribution
b) Determine the value for the standard deviation (o) of the associated distribution.

Answers

Answer:

a) The mean is [tex]\mu = 60[/tex]

b) The standard deviation is [tex]\sigma = 9[/tex]

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

The probability a student selected at random takes at least 55.50 minutes to complete the examination equals 0.6915.

This means that when X = 55.5, Z has a pvalue of 1 - 0.6915 = 0.3085. This means that when [tex]X = 55.5, Z = -0.5[/tex]

So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]-0.5 = \frac{55.5 - \mu}{\sigma}[/tex]

[tex]-0.5\sigma = 55.5 - \mu[/tex]

[tex]\mu = 55.5 + 0.5\sigma[/tex]

The probability a student selected at random takes no more than 71.52 minutes to complete the examination equals 0.8997.

This means that when X = 71.52, Z has a pvalue of 0.8997. This means that when [tex]X = 71.52, Z = 1.28[/tex]

So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]1.28 = \frac{71.52 - \mu}{\sigma}[/tex]

[tex]1.28\sigma = 71.52 - \mu[/tex]

[tex]\mu = 71.52 - 1.28\sigma[/tex]

Since we also have that [tex]\mu = 55.5 + 0.5\sigma[/tex]

[tex]55.5 + 0.5\sigma = 71.52 - 1.28\sigma[/tex]

[tex]1.78\sigma = 71.52 - 55.5[/tex]

[tex]\sigma = \frac{(71.52 - 55.5)}{1.78}[/tex]

[tex]\sigma = 9[/tex]

[tex]\mu = 55.5 + 0.5\sigma = 55.5 + 0.5*9 = 55.5 + 4.5 = 60[/tex]

Question

The mean is [tex]\mu = 60[/tex]

The standard deviation is [tex]\sigma = 9[/tex]

The range of this function is ([tex]y\geq -5[/tex]), this is because all outputs are greater than (-5), rather (-5) is the lowest output that one can have.

The function is [tex]|x|-5=y[/tex]. As one can see, the function as the shape of an absolute value function, the v-shape composed of two ([tex]y=x[/tex]) lines facing opposite directions.

Scientific notation usually writes as c x 10^n, where c is between 1 and 10. The coefficient of B 75.3 is greater than 10, and also is not in the range of 1 and 10, so b is used scientific notation incorrectly.
