Answer:
2 integers (2 and -2)Step-by-step explanation:
Given the inequality (x²– 4)(x² – 10) < 0, we are to find the number of integers that satisfies the inequality
From (x²– 4)(x² – 10) < 0, (x²– 4)< 0 and (x² – 10) < 0
For (x²– 4)< 0;
x²<4
take the square root of both sides;
√x²<√4
x < ±2
x<2 and x<-2
Similarly for (x²– 10)< 0;
x²<10
take the square root of both sides;
√x²<±√10
x < ±√10
x<√10 and x<-√10
Note that √10 is not an integer but an irrational number. An integer should be a negative or positive whole number. Therefore the amount of integers that satisfies the equation is 2 i.e 2 and -2

Step-by-step explanation:
beef hope me I need you to answer the question. What is n * 54 - 688-20 =???³
Answer:n= 1/3d - 2/3m
Step-by-step explanation:
d=2m+3n
Step 1: Flip the equation.
2m+3n=d
Step 2: Add -2m to both sides.
2m+3n+−2m=d+−2m
3n=d−2m
Step 3: Divide both sides by 3.
3n/3 = d-2m/3
Therefore
n= 1/3d - 2/3m

Answer:
n = d - 2m
3*
Step-by-step explanation:
First we want to get n alone on one side, so we should subtract 2m from both side;
d = 2m + 3n
3n = d - 2m
Now to get n by itself, we need to divide by 3 from both sides;
3n = d - 2m
n = d - 2m
3*
*Pretend there is a fraction bar between d - 2m and 3

The area of a rectangle is x 2 – 3x – 28. If the
length is x + 4, find the width.
Answer:
-4 square units
Step-by-step explanation:
a = l × b
x2 - 3x - 28 = (x +4)(×)
x2 - 3x - 28 = x2 + 4x
-3x - 28 - 4x = 0
-7x - 28 = 0
-7x = 28
x = -4

9.8 < 20 – 9.8t < 20
Answer:
0 < t < 1.04 or t ∈ (0, 1.04)
Step-by-step explanation:
Solving in steps:
9.8 < 20 – 9.8t < 20 9.8 - 20 < -9.8t < 20 - 20 ⇒ subtract 20 from all sides-10.2 < -9.8t < 0 ⇒ divide all sides by -9.8, this changes inequality signs to reverse0< t < 10.2/9.80 < t < 1.04 or t ∈ (0, 1.04)If AB = 8 and BC = 24, then AC =
If AB = 17 and AC = 68, then BC =
Answer:
(i) The length of AC is 32 units, (ii) The length of BC is 51 units.
Step-by-step explanation:
(i) Let suppose that AB and BC are collinear to each other, that is, that both segments are contained in the same line. Algebraically, it can be translated into this identity:
[tex]AC = AB + BC[/tex]
If we know that [tex]AB = 8[/tex] and [tex]BC = 24[/tex], then:
[tex]AC = 8 + 24[/tex]
[tex]AC = 32[/tex]
The length of AC is 32 units.
(ii) Let suppose that AB and AC are collinear to each other, that is, that both segments are contained in the same line. Algebraically, it can be translated into this identity:
[tex]AC = AB + BC[/tex]
[tex]BC = AC - AB[/tex]
If we know that [tex]AC = 68[/tex] and [tex]AB = 17[/tex], then:
[tex]BC = 68-17[/tex]
[tex]BC = 51[/tex]
The length of BC is 51 units.
What is the midpoint of the line segment? Drag the coordinates to the boxes to correctly match the endpoints and midpoint.
Hey there! I'm happy to help!
LINE SEGMENT 1
To find the x value of the midpoint, you add the x values and divide by 2.
-1/3+4/3=1
1/2=1/2
For the y value, you add the y values and divide by 2.
7/5+5/2= 3 9/10
3 9/10÷2=1 19/20 or 39/20.
So, our midpoint is (1/2, 39/20).
LINE SEGMENT 2
X-Values
5+(-1)=5-1=4
4/2=2
Y-Values
√3+5√3=6√3
6√3÷2=3√3
So, our midpoint is (2, 3√3).

Step-by-step explanation:
In order to find an expression equivalent to [tex]4(x+2y)[/tex], we want to simplify the equation down.
To do this, we can see that we can apply the distributive property on this equation. Basically, we multiply every term in the parentheses by 4.

Which factor is greater 2/5 or 2/3 how can you tell which fraction is larger (looking for the explanation )
Answer:2/3
Step-by-step explanation The fractions 2/3 and 2/5 have the same numerator. The denominator 3 in the fraction 2/3 means that the unit has less parts, making the parts larger. Therefore, 2/3 is larger than 2/5 . The larger the denominator the smaller the fraction.

Find the absolute deviation for the data
Answer:5.2
Step-by-step explanation:
I have a MAD calculator
The mean absolute deviation for the given data will be equal to 5.
What is the mean absolute deviation?The average of the absolute deviations from a central point makes up the average absolute deviation of a data collection. It is a statistical summary of statistical variability or dispersion.
The formula used to calculate MAD is given below:-
[tex]\rm\dfrac{1}{n}\sum|X_i-m|[/tex]
The given data set is 5 18 6 18 and 13. First, calculate the mean of the given data.
Mean = 12
The MAD will be calculated as below:-
MAD = ( 1 / 5 ) [ | ( 5 - 12) | + | ( 18 - 12) | + | ( 6- 12 ) | + | ( 18- 12) | + | ( 12 - 12) |]
MAD = ( 7 + 6 + 6 + 6 ) / 5 = 5
Therefore, the mean absolute deviation for the given data will be equal to 5.

Susan is correct. If you divide the unit price (the price of each individual soda) by the number of people, you will get the total cost of the soda. Or in other words, how much money you're putting down to buy this soda for X amount of people. John is incorrect because by dividing the cost of a 12 pack soda by the number of sodas, he is determining the cost of each individual soda, not the total cost.
