HELP PLSSSSSSSSS
5.6
17.0
89
90
Answer:
5.6
Step-by-step explanation:
Sheryl got the following scores on her spelling tests.
95, 89, 99, 85, 82
Mean = sum of all observations/ Number of observations
Sum of all observations [tex]=95+89+99+85+82=450[/tex]
Number of observations = 5
So,
Mean [tex]=\frac{450}{5}=90[/tex]
Let M denotes the mean
Mean absolute deviation [tex]=\frac{\sum_{i=1}^{n}\left | x_i-M \right |}{n}[/tex]
Put [tex]n=5[/tex]
So,
Mean absolute deviation [tex]=\frac{\sum_{i=1}^{5}\left | x_i-M \right |}{5}=\frac{|95-90|+|89-90|+|99-90|+|85-90|+|82-90|}{5}=\frac{5+1+9+5+8}{5} =\frac{28}{5}=5.6[/tex]

What is the value of 58 ? (1 point)
Answer:
1/25
Step-by-step explanation:
Answer:
Step-by-step explanation: The absolute value of 58 is the distance between 58 and 0 on a number line. See illustration below where x is 58: Since the distance between 58 and 0 on a number line is 58, we get the answer as follows: |58| = 58. Note that the absolute value of 58 can also be written as abs (58) which may be useful to know if you have a good calculator.

If you divide 78 by 34, will the quotient be greater than or less than 34? (Please help I'm desperate)
Answer:
The quotient will be less than 34
Step-by-step explanation:
When we talk of quotient, we are simply referring to the result of division.
Now, let’s divide 78 by 34, our answer is 2 10/34. The answer is slightly above two which in all terms is really less than 34.
So the correct answer to our question is that the quotient will be less than 34

Paul is going to purchase orange juice and soda water for a new fruit punch recipe. The recipe calls for 3.5 times as many bottles of soda water as orange juice. If he has $20.55, what is the most bottles of orange juice he can buy if orange juice costs $3.70 per bottle and soda water costs $0.90 per bottle?
Answer:
10.5 bottles of orange juice
Step-by-step explanation:
Paul is going to purchase orange juice and soda water for a new fruit punch recipe. The recipe calls for 3.5 times as many bottles of soda water as orange juice. If he has $20.55, what is the most bottles of orange juice he can buy if orange juice costs $3.70 per bottle and soda water costs $0.90 per bottle?
Number of bottles of orange juice = x
Number of bottles of soda water = y
The recipe calls for 3.5 times as many bottles of soda water as orange juice.
Hence,
x = 3.5y
If he has $20.55, what is the most bottles of orange juice he can buy if orange juice costs $3.70 per bottle and soda water costs $0.90 per bottle
We have:
3.70y + 0.90× 3.5= 20.55
3.70y + 3.15y = 20.55
6.85 = 20.55
y = 20.55/6.85
y = 3 bottles
Since, Number of bottles of soda water = y, Number of bottles of soda water = 3
Note that: x = 3.5y
x = 3.5 × 3
x = 10.5 bottles
Number of bottles of orange juice = x, Hence, number of bottles of orange juice = 10.5 bottles

Step-by-step explanation:
When lava is expelled from a volcano, it temperature may vary from 700 degrees Celsius to 1200 degrees Celsius. Write an absolute value equation that represents the minimum and maximum temperatures of lava. Use x to represent the temperature.
Equation:__
Answer:
Ix - 950°C I ≤ 250°C
Step-by-step explanation:
We are told that the temperature may vary from 700 degrees Celsius to 1200 degrees Celsius.
And that this temperature is x.
This means that the minimum value of x is 700°C while maximum of x is 1200 °C
Let's find the average of the two temperature limits given:
x_avg = (700 + 1200)/2 =
x_avg = 1900/2
x_avg = 950 °C
Now let's find the distance between the average and either maximum or minimum.
d_avg = (1200 - 700)/2
d_avg = 500/2
d_avg = 250°C.
Now absolute value equation will be in the form of;
Ix - x_avgI ≤ d_avg
Thus;
Ix - 950°C I ≤ 250°C

Step-by-step explanation:
Apply the fractions formula for addition, to
− 45 + 23
and solve
( −4 × 3 ) + ( 2 × 5 ) 5 × 3
= − 12 + 10/15
= −2/15

Mira and Sasha observed two points, P and Q, on a number line.
A number line is shown from negative 2 to positive 2 with increments of 2 over 8. A point P is shown at the seventh tick mark to the left of 0, and a point Q is shown at the seventh tick mark to the right of 0.
Sasha said that the absolute values of the numbers represented by the two points are different.
Mira said that the absolute values of the numbers represented by the two points are the same.
Which of the following explains who is correct?
A Sasha, because the points are of different signs
B Sasha, because the points are at different locations

HELP, I WILL GIVE ALOT OF POINTS AND BRAINLYEST
Answer:
C
Step-by-step explanation:
first, let's find the midpoint of line TR.
((x1+x2)/2, (y1+y2)/2)
(4+8)/2= x-coordinate= 6
(-4+-4)/2=y-coordinate=-4
(6,-4) is the point of A
now, use the distance formula for U (5,-6) and A (6,-4)
d= sqrt (x2-x1)^2 + (y2-y1)^2
d= sqrt (6-5)^2 + (-4-(-6))^2
d= sqrt (1+4)
d= sqrt 5
C. sqrt 5

Line WV is perpendicular to both line RS and line TU.
On a coordinate plane, 3 lines are shown. Line V W goes through (negative 1, 5) and (1, 5). Line R S goes through (negative 5, 3) and (5, 1). Line T U goes through (negative 1, negative 2) and (4, negative 3).
Which statement must be true about line TU?
Line TU is parallel to line RS.
Line TU is perpendicular to line RS.
Line TU has no slope.
Line TU has a slope of –5
Answer:
Line TU is parallel to line RS
Step-by-step explanation:
I just got a 100 on the test
Line TU is parallel to line RS and has a slope of -1/5
What is a linear equation?
A linear equation is in the form:
y = mx + b
Where m is the slope and b is the y intercept.
Line V W goes through (-1, 5) and (1, 5). Line R S goes through (-5, 3) and (5, 1). Line T U goes through (-1,-2) and (4, -3).
Slope of VW = (5 - 5)/(1- (-1)) = 0
Slope of RS = (1 - 3) / (5 -(-5)) = -1/5
Slope of TU = (-3 - (-2))/(4 - (-1)) = -1/5
Line TU is parallel to line RS and has a slope of -1/5

Lance and Brandon purchased items at the sporting goods store and spent the same amount of money. Lance bought 18 shirts for his team, and Brandon bought 12 of the same shirts for his team plus a $75 pair of shoes. How much did each shirt cost?
Answer:
$12.50
Step-by-step explanation:
18 - 12 = 6
Brandon bought 6 less than Lance and payed $75 dollars shoes.
That means that 6 shirts cost $75.
We need to divide 6 from 75
75/6 = 12.5
So each shirt costs $12.50.
Hope this helped

Alex bar and Carl are brothers Alex is the oldest and Carl is the youngest the some of the ages of the three brothers is 42 Alex his age is three more than twice Carl's age the difference between Barts in Carl's ages is seven years how old is each brother
Answer:
Alex = 19 years
Bart's = 15 years
Carl = 8 years
Step-by-step explanation:
Let us represent their ages as
Alex = x
Bart's = y
Carl = z
the sum of the ages of the three brothers is 42
x + y + z = 42
Alex his age is three more than twice Carl's age
x = 2z + 3
The difference between Barts in Carl's ages is seven years
y - z = 7
y = 7 + z
Hence: we Substitute
x + y + z = 42
2z + 3 + 7 + z + z = 42
Collect like terms
2z + z + z + 10 = 42
4z = 42 - 10
4z = 32
z = 32/4
z = 8 years
Hence, Carl = 8 years old
a) y = 7 + z
y = 7 + 8
y = 15 years.
Hence, Bart's is 15 years old
b)x = 2z + 3
x = 2(8) + 3
= 16 + 3
= 19 years
Therefore, Alex is 19 years old.
