Answer:
Mean, m = 72
Step-by-step explanation:
It is given that, Carl earned grades of 62, 78, 59, and 89 on four math tests.
It is required to find the mean of his grades.
Mean of a data is given by :
[tex]m=\dfrac{\text{sum of observations}}{\text{total no of observations}}[/tex]
Sum of observations is 62 + 78 + 59 + 89 = 288
Total no of observations are 4
So, mean of his grades is :
[tex]m=\dfrac{288}{4}\\\\m=72[/tex]
So, the mean of his grades is 72.
Option C is correct. If Carl earned grades of 62, 78, 59, and 89 on four math tests, the mean of his grades is 72
Mean is the average of the given data. It is expressed mathematically as:
[tex]\overlibe x=\frac{\sum x}{N}[/tex]
[tex]\sum x[/tex] is the sum of the variables
N is the total test taken
[tex]\sum x = 62 + 78 + 59 + 89\\\sum x = 288\\\\N = 4[/tex]
Substitute the resulting values into the mean formula:
[tex]\overline x = \frac{288}{4}\\ \overline x =72[/tex]
This shows that the mean of his grades is 72

The sum of four consecutive integers is -10. What are the integer
Answer:
see below
Step-by-step explanation:
Let x be the first integer
x+1 is the next integer
x+2 = next integer
x+3 = last integer
The sum of the 4 integers is -10
x+ x+1 + x+2 + x+3 = -10
Combine like terms
4x+6 = -10
Subtract 6 from each side
4x+6-6 = -10-6
4x = -16
Divide each side by 4
4x/4 = -16/4
x = -4
x+1 = -3
x+2 = -2
x+1 =-1
The integers are -4, -3, -2 ,-1
What is the median number of carrots in a one-pound bag?
Answer:
To find the medium order the numbers from least to greatest. Then each time cross off one number from the left side and the right. When you get down to 1 or you have 2 left those are your medians. If you have 2 numbers add them up and divide them by 2. If you have 1 that is your medium. Hope this helps. The median is 70.

An experiment consists of spinning a spinner. Use the results in the table to find the experimental probability that the spinner does not land on yellow. Express your answer as a fraction in simplest form.
Red = 12
Blue = 10
Yellow = 6
A. 11/14
B. 3/7
C. 4/7
D. 3/14
Answer:
A. 11/14
Step-by-step explanation:
i hope this helps :)
The Probability of an Event P(E) is that the spinner does not land on yellow is 11/7.
An experiment consists of spinning a spinner.
Red = 12
Blue = 10
Yellow = 6
We have to determine,
The experimental probability is that the spinner does not land on yellow.
The total number of spinner= 12+10+6
The total number of spinner=28.
What is the formula for the experimental probability?Probability of an Event P(E) = Number of times an event occurs / Total number of trials.
The number of trials to not land on yellow is,
12+10=22
Therefore the Probability of an Event P(E) is given by,
[tex]P(E)=\frac{22}{28}[/tex]
[tex]P(E)=\frac{11}{14}[/tex]
Therefore option A is correct.

Mr. Suárez wants to paint his storage shed. He needs to calculate the lateral surface area of the shed so that he will know how much paint to buy. The shed is in the shape of a rectangular prism with the dimensions shown below. Including the doors, what is the lateral surface area of the storage shed in square feet? 784 ft2 266 ft2 532 ft2 336 ft2
Answer:
Lateral surface area of the storage shed = 336 ft²
Step-by-step explanation:
The picture is the complete question.
The shed is in the shape of a rectangular prism. The lateral surface area of the storage shed can be calculated below. The lateral area is the sides of the prism.
lateral area of a rectangular prism = 2h (l + w)
where
l = length
h = height
w = width
h = 8 ft
l = 14 ft
w = 7 ft
lateral area of a rectangular prism = 2h (l + w)
lateral area of a rectangular prism = 2 × 8 × (14 + 7)
lateral area of a rectangular prism = 16 (21)
lateral area of a rectangular prism = 336 ft²
Lateral surface area of the storage shed = 336 ft²

Pendulum formula need help asap
Answer:
T = 2*PI* sq root (L / g)
Squaring both sides
T^2 = 4PI^2 * L/g
g = 4PI^2 * L / T^2
g = 4PI^2 * 1 / (3.27)^2
g = 39.4784176044 * 1 / 10.6929

What are the solutions to this quadratic equation? x^2+6x-5=0
Answer:
[tex]x = -3+\sqrt{14} \\x=-3-\sqrt{14}[/tex]
Step-by-step explanation:
x + 6x - 5 = 0
Since you can't factor the equation, use the quadratic formula.
Your equation is already in the form of ax + bx + c.
[tex]x=\frac{-b\frac{+}{} \sqrt{b^{2} -4ac} }{2a}[/tex]
Based on your equation a = 1 b = 6 c = -5. Plug in the numbers and solve for x.
[tex]x = \frac{-6\frac{+}{} \sqrt{6^{2} -4(1)(-5)} }{2(1)} \\x = \frac{-6\frac{+}{} \sqrt{36+20 } }{2} \\x=\frac{-6\frac{+}{}\sqrt{56} }{2} \\x=\frac{-6\frac{+}{}2\sqrt{14} }{2} \\\\x = -3+\sqrt{14} \\x=-3-\sqrt{14}[/tex]

Ty’s experimental probability of winning a certain game is 1/3. Jana’s expiremental probability of winning the same game is 3/4. If Ty and Jana each played the game 120 times, how many more games would Jana expect to win over Ty?
Answer:
Jana is expected to win 40 more games over Ty.
Step-by-step explanation:
If Ty plays the game 120 times, he is expected to win in 1/3 part of 120 games, which is ( 1/3 * 120 =) 40 games.
If Jana plays the game 120 times, she is expected to win in 2/3 part of 120 games, which is ( 2/3 * 120 =) 80 games.
If Jana is expected to win 80 times an Ty is expected to 40 times, then Jana is expected to win ( 80 - 40 =) 40 more games over Ty.

Write the equation in standard form and then find the center (h, k) and
x^2+8x+ y2 + 4y - 5= 0
Answer:
Center is at (-4, -2) and the radius = 5.
Step-by-step explanation:
Convert to Standard form:
x^2 + 8x + y2 + 4y - 5= 0
Completing the square:
(x + 4)^2 - 16 + (y + 2)^2 - 4 = 5
(x + 4)^2 + (y + 2)^2 = 5 + 16 + 4
(x + 4)^2 + (y + 2)^2 = 25
(x - h)^2 + (y - k)^2 = r^2 Comparing:-
The center is at (-4, -2) and the radius = 5.
