Answer:

When making bread from scratch, the recipe calls for 2/3 cup of water

Step-by-step explanation:

Answer:

The number of observations in the data set expected to be between the values 91 and 121 is of 2853.

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed random variable:

68% of the measures are within 1 standard deviation of the mean.

95% of the measures are within 2 standard deviation of the mean.

99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean = 101, Standard deviation = 10

Percentage of of observations in the data set expected to be between the values 91 and 121.

91 = 101 - 10

So 91 is one standard deviation below the mean.

121 = 101 + 2*10

So 121 is two standard deviations above the mean

The normal distribution is symmetric, which means that 50% of the measures are below the mean and 50% are above.

Of those 50% below the mean, 68% are between one standard deviation below the mean(91) and the mean(101).

Of those 50% above the mean, 95% are between the mean(101) and two standard deviations above the mean(121).

So the percentage of observations in this interval is of:

[tex]P = 0.5*0.68 + 0.5*0.95 = 0.815[/tex]

Number of observations in the interval

81.5% of 3500. So

0.815*3500 = 2853

The number of observations in the data set expected to be between the values 91 and 121 is of 2853.

Answer:

  $0.70

Step-by-step explanation:

The interest is computed using the formula ...

  I = Prt

where r is the annual rate, and t is the time in years. Banks compute interest using "ordinary interest", which assumes a 360-day year. Trevor's interest is ...

  I = $241(0.0194)(54/360) = $0.70

Answer:

X= 40

Step-by-step explanation:

A triangle always equals 180°. In order to find x, add 75 and 65,

75 + 65 =140

then divide 140 and 180,

180 / 140 = 40

then in order to make sure it's the right answer add 75,65, and 40 together. If it equals to 180, then it's the right answer.

Step-by-step explanation:

-4x - 3 = - 19

Bringing like terms on one side

-4x = - 19 + 3

-4x = - 16

x = - 16/-4

x = 4

Answer:

x=4

Step-by-step explanation:

-4x-3=-19

add -3 to the right side of the equation so -19+3

which will give you -16

then  divide by -4

so x=4

Answer: you are doing hell jesus

Step-by-step explanation:

Answer:

Ok, so when you graph, you want to make sure your point are right. 4, would be im guessing +4, so you would find +4, on your graph across the X axis. Keep that in mind. Then find +3, across the Y axis on your graph. Join the points, and you have your answer.

EXAMPLE

Pete bought a shirt on sale for $

18

18, which is one-half the original price. What was the original price of the shirt?

Solution:

Step 1. Read the problem. Make sure you understand all the words and ideas. You may need to read the problem two or more times. If there are words you don’t understand, look them up in a dictionary or on the Internet.

In this problem, do you understand what is being discussed? Do you understand every word?

Step 2. Identify what you are looking for. It’s hard to find something if you are not sure what it is! Read the problem again and look for words that tell you what you are looking for!

In this problem, the words “what was the original price of the shirt” tell you what you are looking for: the original price of the shirt.

Step 3. Name what you are looking for. Choose a variable to represent that quantity. You can use any letter for the variable, but it may help to choose one that helps you remember what it represents.

Let

p

=

p= the original price of the shirt

Step 4. Translate into an equation. It may help to first restate the problem in one sentence, with all the important information. Then translate the sentence into an equation.

36, and the shirt was on sale at half the original price.Step 7. Answer the question with a complete sentence.

The problem asked “What was the original price of the shirt?” The answer to the question is: “The original price of the shirt was

$36

$36.”

Step-by-step explanation:

The Commutative property can be used to rewrite 2a + (10 - 4)

This law simply states that with addition and multiplication of numbers, you can change the order of the numbers in the problem and it will not affect the answer.

The commutative property is satisfied not only in addition but also in multiplication. It is given by:

a + b = b + a

a * b = b * a

2a + (10 - 4) = 2a + 6

2a + 6 = 6 + 2a

The Commutative property can be used to rewrite 2a + (10 - 4)

Given:

A figure of a triangle.

To find:

The value of x.

Solution:

In a triangle, angle bisectors intersect each other at a point which is know as incenter. This point is equidistance form the each side.

Using the above property, we get

[tex]4x-2=6x-8[/tex]

[tex]4x-6x=2-8[/tex]

[tex]-2x=-6[/tex]

Divide both sides by -2.

[tex]x=\dfrac{-6}{-2}[/tex]

[tex]x=3[/tex]

Therefore, the value of x is 3.
