A certain missing number will result in the expression 20 + 24 when using the Distributive Property. What number must be multiplied by ( 5 + 6 ) to result in the expression: 20 + 24
Answer:
4
Step-by-step explanation:
You want to know what number, multiplied by (5 +6), gives 20 +24.
Distributive propertyFor some number 'a', you want ...
a(5 +6) = (20 +24)
We can solve for 'a' in the usual way.
11a = 44 . . . . simplify
a = 44/11 = 4 . . . . divide by the coefficient of 'a'
The missing number is 4: 4(5 +6) = 20 +24.
__
Additional comment
You can also look at it term by term:
5a = 20 ⇒ a = 4
6a = 24 ⇒ a = 4 . . . . the same factor, as you want it to be

The property illustrated ca be classified as the transitive property of equality
Transitive property of equalityEquation are expressions separated by an equal sign. For transitive property, if two system of equation are equal, and the first is equal to the second, then they 2nd is equal to the third, they are transitive.
According to the transitive property of equality, two quantities that are equal to the same thing are equal to each other. For instance If x = 10 and 10 = y, then x = y.

What is the vertex form of y equals 2 x squared minus 8 x plus 1?
According to the given information, the vertex form is 2(x - 8)² + 1.
What do we mean by vertex form?A quadratic function has the vertex form f(x) = a(x - h)2 + k, where a, h, and k are constants. A vertex form in geometry is a location where two or more curves, lines, or edges converge. As a result of this definition, vertices are the intersection of two lines that create an angle as well as the corners of polygons and polyhedra. The four corners of a square, for instance, are each referred to as a vertex.So, vertex form:
Vertex form: f(x) = a(x - h)² + kNow, substitute the given values as:
2(x - 8)² + 1Therefore, according to the given information, the vertex form is 2(x - 8)² + 1.

elane has $7.00 total in dimes and nickels in her coin jar. the number of dimes that elane has is seven less than three times the number of nickels. how many of each coin does elane have
SHOW WORK PLS AND THE EQUATION
Answer:
Let the number of 50p coins be x
and the number of 25p coins be 2x
Therefore,
Value of 50p coins = 50x p
and value of 25p coins = 2 * 25x p
= 50x p
Total value = Rs 34 = 34 * 100 p= 3400p
According to the question,
50x p + 50x p = 3400 p
=100x p = 3400p
= x = 3400p/100p
= x = 34
Therefore , number of 50p coins =34
and , number of 25p coins = 34 * 2 = 68

If an Apple Computer store sells computers for $1,234.88 and the computers cost $10,896 per dozen, then the dollar markup for each computer is $326.88 and the percentage markup is 36%
Given,
An Apple Computer store sells computers = $1234.88
The cost of computers per dozen = $10896
Cost of one computer = [tex]\frac{10896}{12}[/tex] = $908
Then the dollar markup for each computer = 1234.88-908
=$326.88
Percentage markup = [tex]\frac{326.88}{908}[/tex]×100
=36%

The side-lengths of a triangle are increased by a scale factor of 4. Predict
how this change will affect the area.
A. The area will be one-fourth the original area.
B. The area will be 4 times greater.
C. The area will be 16 times greater.
D. The area will be increased by 4 units.
If the side-lengths of a triangle are increased by a scale factor of 4 then the area will be 16 times greater.
As given in the question,
Let 'a' be the base of the triangle
and 'h' be the height of the triangle
Area of the triangle = (1/2)×a× h
Side length increased by scale factor 4
New base = 4a
New height=4h
New area=(1/2)×4a×4h
= 16×(1/2)×a ×h
= 16 times the original area
Therefore, if the side-lengths of a triangle are increased by a scale factor of 4 then the area will be 16 times greater.

0.50 and 1 probability values indicates an event that is certain to happen
An event that is certain to happen has a probability of 1. An event that cannot possibly happen has a probability of zero. If there is a chance that an event will happen, then its probability is between zero and 1.
Probability of an event can not be negative.
We can easily discard first two options i.e. -0.80 and -0.60 as they are negative values.
Last two options i.e., 0.5 and 1 are positive values and they also lies in the range from 0 to 1. We can say that these values are considerable.

Step-by-step explanation:
Answer:
Step-by-step explanation:
Slope intercept form is y=mx+b
Where m is the slope
general form is ax+by+c=0
this means, 2 is b
3x-2y=-16
y=3/2x+8
Now
subtract ax from both sides
3x -2y-3x= -16-3x
-2y=-16-3x
Subtract C from both sides
-2y=-3x+-16
divide both sides by b
y=-3/-2 x -16/-2
the slope is given by -a/b and the y intercept is given by -c/b
simplify
y=3/2x+8

Use the information given to find a convenient class width. Then list the class boundaries that can be used to create a relative frequency histogram. (Round your class width up to the nearest multiple of 5. Use the minimum value as the smallest class boundary. Enter your class boundaries as a comma separated list.) 8 classes for n = 75 measurements; minimum value = 50; maximum value = 205
Class boundaries list: 50,70,90,110,130,150,170,190,210
1. Calculate the range.
range= maximum value - minimum value= 205 - 50 =155
2. Divide the range by the number of classes.

To calculate range, subtract the smallest number from the largest number in the set.The statistical distributions' characteristics are described by the terms mean, median, mode, and range. The set of all potential values for terms that indicate predetermined events is known as a distribution in statistics. A term's value stated as a variable is referred to as a random variable.
The two main categories of statistical distributions are as follows. There are discrete random variables in the first category. This indicates that each phrase has a distinct, precise numerical value. A continuous random variable is present in the distribution of the second major kind.
