I Don't Understand This Very Much, But If Someone Could Give Me An Explanation, That Would Be Appreciated!

Answers

Answer 1

Answer:

119.0 cm²

Step-by-step explanation:

What is surface area

It is the area of the outside part of anything. Surface area is also called total surface area.

As we can see from the pyramid, it has a square base. How do I know that it is a square base, is by seeing the dimensions of the base, which are 6.4 cm by 6.4 cm in this pyramid. And we already know from basic Geometry that a square has 4 equal sides. So we call it a square pyramid.

So to find the total surface area of this square pyramid, we need the area of the 4 triangular faces and the area of the square base.

So t.s.a of the pyramid = 4 × Area of each triangular face + Area of the square base.

So, total surface area = Area of square base + Area of the four triangular faces.

     total surface area = (length²) + (4 × [tex]\frac{1}{2}[/tex] × base × height)

     total surface area = (6.4 × 6.4) + (4 × [tex]\frac{1}{2}[/tex] × 6.4 × 6.1)

     total surface area = 40.96 + 78.08

     total surface area = 119.04 cm² ≈ 119.0 cm² (to the nearest tenth) (Answer)

Answer 2
119.0cm^2

So t.s.a of the pyramid = 4 × Area of each
triangular face + Area of the square base.
So, total surface area = Area of square base +
Area of the four triangular faces.
total surface area = (length?) + (4 × ;
× base × height)
total surface area = (6.4 x 6.4) + (4 x = x
6.4 x 6.1)
total surface area = 40.96 + 78.08
total surface area = 119.04 cm^2 ~ 119.0 cm^2

Ross and Rachel are in NYC shopping. After each store they visit, they have less and less money each. Use the system of equations below to
A) determine the number of stores it will take for both to have the same amount of money.
B) determine how much spending money they will both have at this time.

ROSS: a = 927 - 45s
RACHEL: a = 792 - 36s

Answers

Let’s solve for “a” and “s”.

a = 927 - 45s
a = 792 - 36s

927 - 45s = 792 - 36s
927 - 792 = 45s - 36s
135 = 9s
s = 15
a = 927 - (45 x 15) = 252

Male and female high school students reported how many hours they worked each week in summer jobs. The data is represented in the following box plots:

two box plots shown. The top one is labeled Males. Minimum at 1, Q1 at 3, median at 10.5, Q3 at 14, maximum at 21. The bottom box plot is labeled Females. Minimum at 0, Q1 at 15, median at 18, Q3 at 21, no maximum shown

Identify any values of data that might affect the statistical measures of spread and center.

The females worked more than the males, and the female Q3 equals the top of the range.
The spread and center are skewed due to the fourth quartile missing with the females.
There is a significant outlier at the low end for the females.
The males have a high outlier, and the females have a low outlier

A computer is used to generate passwords made up of numbers 0 through 9 and uppercase letters. The computer generates 500 passwords one character at a time.

A uniform probability model is used to predict the first character in the password.

What is the prediction for the number of passwords in which the first character is a number?

Round your answer to the nearest whole number.


69 passwords

139 passwords

192 passwords

292 passwords

Answers

Answer:

139

Step-by-step explanation:

Just took the quiz on K-12

Hope its not to late

The prediction for the number of passwords in which the first character is a number is 139. Therefore, option B is the correct answer.

What is the probability?

Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.

We know that, probability of an event = Number of favourable outcomes/Total number of outcomes.

The answer is 192 passwords. This is because there is an equal probability of each character (0-9 and uppercase letters) being chosen as the first character of a password.

Since there are 10 different numbers (0-9) and 26 uppercase letters, the probability of the first character being a number is 10/36

If 500 passwords are generated, the expected number of passwords in which the first character is a number is 500 ×10/36

= 5000/36

= 138.88

≈ 139

Therefore, option B is the correct answer.

Consider the possibilities:

One option: cut the pan of brownies into the 12 pieces

             ⇒ so that everyone gets one piece of brownie

Second Option: cut the pan of brownies into 24 pieces

             ⇒ so that everyone can gets two piece of brownie

In other words, you can cut a number of pieces that must be divisible by 12 in other to split equally within the group.

The conversion of a temperature from Celsius to Fahrenheit is represented by the expression below, where C is the temperature in degrees Celsius.

9/5 x C + 32

36° F
B.
68° F
C.
48° F
D.
52° F

Answers

Answer:

B.

Step-by-step explanation:

C= 20 degrees Celsius

20 x 9/5 = 180/5

180 divided by 5 = 36 degrees celsius

Then you do 36 degrees celsius + 32 and you get 68.

So therefore 20 degrees celsius is eqivalent to 68 degrees Fahrenheit.

The mean and median will both be decreased because you are removing the largest number value from the number line, logically it must decrease.

Answer:

Before Suzanne left:

Mean = 53,333

Median = 45,000

After Suzanne left:

Mean = $44,000

Median =  $44,000

Since the larger number was taken away the mean and median decreased after she left. The 100,000 is an outlier which basically holds up the mean and median salary.
