Robert has attended 32 out of 40 after school band practices this year based on his record of attendance which is the probability that Robert will attend band practice in the future?
Answer:
4/5
Step-by-step explanation:
32/40 is how often he has come so far. You would need to simplify that fraction down to the lowest, which is 4/5.

Answer:
Total Area = 532 m²
Step-by-step explanation:
Triangle = ½bh.
Rectangle = lw.
Total Area = sum of individual areas =
(8 m × 16 m) / 2 + (16 m × 18 m) / 2
+ (18 m × 18 m) =
(64 m²) + (144 m²) + (324 m²) =
532 m²
Give the following sequence for f(x) = 4x^2 - x , when x is -4, 1, 2
O 58, 14, 3
0-64, - 14, 3
O 68, 14, 3
0 7, 14, 3
Answer:
O 68, 14, 3
Step-by-step explanation:
Given:
f(x) = 4x² - x
When x = -4
f(x) = 4x² - x
= 4(-4)² - (-4)
= 4(16) + 4
= 64 + 4
f(x) = 68
When x = 1
f(x) = 4x² - x
= 4(1)² - 1
= 4(1) - 1
= 4 - 1
f(x) = 3
When x = 2
f(x) = 4x² - x
= 4(2)² - 2
= 4(4) - 2
= 16 - 2
f(x) = 14
The answer = 68, 3, 14

Answer:
[tex]m =13[/tex]
Step-by-step explanation:
Given
The attached dataset
Required
The mean absolute deviation
First, calculate the mean
[tex]\bar x = \frac{\sum x}{n}[/tex]
So, we have:
[tex]\bar x = \frac{42+40+39+76+71+55+68+65}{8}[/tex]
[tex]\bar x = \frac{456}{8}[/tex]
[tex]\bar x = 57[/tex]
The mean absolute deviation (m) is:
[tex]m =\frac{1}{n} \sum|x - \bar x|[/tex]
So, we have:
[tex]m =\frac{1}{8} (|42 - 57| + |40 - 57| + |39 - 57| + |76 - 57| + |71 - 57| + |55 - 57| + |68 - 57| + |65 - 57|)[/tex]
Using a calculator, we have:
[tex]m =\frac{1}{8} (|-15| + |-17| + |-18| + |19| + |14| + |-2| + |11| + |8|)[/tex]
Remove absolute bracket
[tex]m =\frac{1}{8} (15 + 17 + 18 + 19 + 14 + 2 + 11 + 8)[/tex]
[tex]m =\frac{1}{8} *104[/tex]
[tex]m =13[/tex]
The mean absolute deviation is 13

3*40 = 120
Suppose that AKL M is isosceles with base MK.
Suppose also that m 2 M= (3x+36) and m 2 K = (4x +31)
Find the degree measure of each angle in the triangle.
m ZK = 0
m 2L =
m ZM =
MA
K
(3x +36)
(4x +31).
Х
Answer:
m<K = 51°
m<L = 78°
m<M = 51°
Step-by-step explanation:
Base angles of an isosceles ∆ are equal to each other, therefore,
m<M = m<K
Substitute
3x + 36 = 4x + 31
Collect like terms and solve for x
3x - 4x = -36 + 31
-x = -5
Divide both sides by -1
x = 5
Let's find each degree measure using the value of x
m<K = 4x + 31
Plug in the value of x
m<K = 4(5) + 31
m<K = 20 + 31
m<K = 51°
m<M = 3x + 36
= 3(5) + 36
= 15 + 36
m<M = 51°
m<L = 180° - (m<M + m<K) (sum of triangle theorem)
Substitute
m<L = 180 - (51 + 51)
m<L = 78°
I NEED HELP ASAP PLEASE!! ;)
Answer:
7 inches
Step-by-step explanation:
First you have to find the average height of each class.
4th Grade:
56, 47, 54, 51, 53, 58, 48, 54, 46, 53
Then you have add it all up and divide it by how many students there are.
56 + 47 + 54 + 51 + 53 + 58 + 48 + 54 + 46 + 53 = 520
520 ➗10= 52
Same process for the 7th Grade.
You end up getting 52 and 59. You then Subtract it to get the answer to the question.
52 - 59= 7 inches
Maria says the mean for the following data set is 5. {5, 7, 2, 8, 9, 1, 2, 5}
What is the actual mean? (Round to the nearest hundredth)
What did Maria do wrong? In other words, what average did she give instead?
Answer:
4.88
Step-by-step explanation:
I used my calculator to do this;
I did stat and I put in the numbers, I clicked calculate and it said the answer was 4.875. Round that to the nearest hundredth and you'll get 4.88.
Answer:
4.88
Step-by-step explanation:
The actual mean is 4.88 to the nearest hundredth. She either approximated the sum of elements to 40 instead of 39 or she approximated the actual mean to the nearest whole number.
I think she gave an approximated average or a rounded average, but I am not sure.
There were 24 students running in a race. How many different arrangements of first,
second, and third place are possible?
8th grade work math.
Answer:
3rd option
Step-by-step explanation:
Consider the coordinates of A and A'
A (0, 0 ) and A' (5, 2 )
This represents a move of + 5 (0 → 5) units in the x- direction and a move of + 2 ( 0 → 2 ) units in the y- direction.
The figure is unchanged and must therefore be a translation with rule
(x, y ) → (x + 5, y + 2 )
solve for x
I tried 10 but it said that it was incorrect
Answer:
5

x = 5
5. Miguel has an after-school job. He works
between 15 and 25 hours each week and is paid
$12 per hour. What is an appropriate domain for
this scenario?
A. All real numbers such that 15
B. All real numbers such that 180 < x < 300
C. All real numbers
D. All real numbers such that x>0
Answer:
The domain is 15 ≤ x ≤ 25
Step-by-step explanation:
The given parameters are;
The number of hours Miguel works each week = Between 15 and 25 hours
The amount he is paid per hour = $12
Therefore, we have;
The domain is all real numbers, 'x', such that 15 ≤ x ≤ 25
The amount Miguel makes each week, 'y' is between; 12 × 15 ≤ A ≤ 12 × 25
Therefore the range is 180 ≤ y ≤ 300.
There are 20 pieces of candy in the box. If 15 of them are hard candies, what percentage of the candies in the box are hard candies?
Answer:percentage of the candies in the box that are hard candies=75%
Step-by-step explanation:
Total pieces of candy in the box=20
Number of candies that are hard =15
Percentage of candies that are hard =Number of candies that are hard / Total pieces of candy in the box x 100
= 15/20 x 100
=75%

.Un recipiente cilíndrico de 5cm de radio y 10cm de altura se llena de agua. Si la masa del recipiente lleno es de 2kg, ¿cuál es la masa del recipiente vacío?
Answer:
La masa del recipiente vacío es 1,2146 kg.
Step-by-step explanation:
La densidad se define como la propiedad que tiene la materia, ya sean sólidos, líquidos o gases, para comprimirse en un espacio determinado. En otras palabras, la densidad es una magnitud que permite medir la cantidad de masa que hay en determinado volumen de una sustancia. Entonces, la expresión para el cálculo de la densidad es el cociente entre la masa de un cuerpo y el volumen que ocupa:
[tex]densidad= \frac{masa}{volumen}[/tex]
Entonces la masa puede ser expresada como:
masa= densidad*volumen
En este caso:
densidad del agua= 1000 [tex]\frac{kg}{m^{3} }[/tex]volumen del recipiente cilíndrico= π*radio²*altura= π*(5 cm)²* 10 cm= π*(0,05 m)²*0,1 m= 7,854*10⁻⁴ m³Reemplazando:
masa= 1000 [tex]\frac{kg}{m^{3} }[/tex] * 7,854*10⁻⁴ m³
masa=0.7854 kg
Si la masa del recipiente lleno es de 2 kg, entonces se le resta la masa de agua calculada:
2 kg - 0,7854 kg= 1,2146 kg
Entonces, la masa del recipiente vacío es 1,2146 kg.
