In a class of 29 students, 9 play an instrument and 23 play a sport. There are5
students who play an instrument and also play a sport. What is the probability that a
student plays an instrument given that they play a sport?
Answer:
5/23
Step-by-step explanation:
23 play a sport and 5 play both an instrument and a sport so 5 out of 23 play an instrument given that they play a sport
The probability that a student plays an instrument given that they play a sport is 5/29.
What is probability?The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.
Given
students who play an instrument and also play a sport = 5
Total student = 29
P(students who play an instrument and also play a sport/Total student) = 5/29

so my question is explain how to find the answer of Pamela ran 3 and 3/4 miles around the school track if each lap is 1/2 mile how many laps did she run and I don't know how to explain the question
Answer:
She ran 7.5 laps
Step-by-step explanation:
Given that:
Total Distance Covered = d = 3 and 3/4 miles
that is: [tex]3\frac{3}{4} = \frac{15}{4}\ miles[/tex]
Distance per mile = l = 1/2 miles
In order to find the number of laps, we have to simply divide the total distance covered by number of miles in one lap.
Let n be the number of laps then
[tex]Number\ of\ laps = \frac{Total\ distance}{Distance\ of\ one\ mile}\\n = \frac{d}{l}\\n = \frac{\frac{15}{4}}{\frac{1}{2}}\\Using\ \frac{\frac{a}{b}}{\frac{c}{d}} => \frac{a}{b} * \frac{d}{c}\\n = \frac{15}{4} * \frac{2}{1}\\n = \frac{30}{4}\\n = 7.5\ laps[/tex]
Hence,
She ran 7.5 laps

Step-by-step explanation:
Rounding each number to the nearest tenth means that you're rounding a number up by one decimal place.
19.75 will become 19.8
2.49 will become 2.5
[tex]19.8 + 2.5 = 22.3[/tex]

Weight varies directly with gravity. If Buzz Aldrin weighted 360 pounds on earth but only 60 pounds on the moon, what is the weight of a person who weighted 54 pounds on the moon.
Answer:
9 pounds weight on moon
Step-by-step explanation:
Given
Variation: Direct
Buzz Adrin
Earth = 360 pounds
Moon = 60 pounds
Required
Determine the weight of 54 pounds
The given parameters can be summarized as:
360 pounds Earth = 60 pounds Moon
54 pounds Earth = x pounds Moon
To solve for x, we start by using cross multiplication:
[tex]360 * x = 60 * 54[/tex]
[tex]360 * x = 3240[/tex]
Divide through by 360
[tex]x = \frac{3240}{360}[/tex]
[tex]x = 9[/tex]
Frank borrowed $7 a week from a friend
for 8 weeks. Which integer represents how
much money Frank owes his friend?
Answer:
The correct integer is -56
Step-by-step explanation:
If Frank borrowed $7 per week for 8 weeks, then the equation we will need to solve is 7 x 8 = m. ("m" will stand for the amount of money Frank owes his friend). We will have to multiply the amount of money per week by the number of weeks which will end up giving us a total of $56 that Frank owes his friend. But since Frank owes his friend money, he is going to lose the money which means it has to be negative which will give us an integer of -56

Compare and Contrast Graph y = 2x + 5 and y=-13x+5. Describe how these lines are alike and how they are different. *
Here are a couple I found:
Similarities:
They have the same y-intercept of (0,5). They are both in slope-intercept form.Differences:
The line of y = -13x + 5 "falls" from left to right. The line of y = 2x + 5 "rises" from left to right. They have different x-intercepts. (y = 2x + 5 intersects (-[tex]\frac{5}{2}[/tex], 0) while y = -13x + 5 intersects at ([tex]\frac{5}{13}[/tex], 0)Explanation:
Slope-intercept form is y = mx + b, and by looking at the equations, they both already fit that format, with m as their slope and b as their y-intercept. Also, since they both have a 5 as that "b," their y-intercepts are the same: (0,5).
As for differences, we can see that the coefficient in place of that "m" is positive in y = 2x + 5 and negative in y = -13x + 5. Therefore, one line would rise due to their slope being positive and one would fall due to their slope being negative. They also have two different x-intercepts, which we can calculate by substituting 0 in place of the y, then isolating x.
rewrite the equation so that y is a function of x. 2x+y = 7

Paige has 1 ½ feet of rope for a project. She only needs 2/3 of it. How much rope does she need?
Answer:
1 foot
Step-by-step explanation:
1 1/2 = 3/2
2/3*3/2 = 1
Answer:
1 foot of rope.
Step-by-step explanation:
For this problem, we need to find 2/3 of 1 ½. 1 ½ equals 3/2. Since the word "of" means multiply, we multiply 3/2 by 2/3. When we do this, we get 1. This means Paige needs 1 foot of rope. I hope this helps!

How many feet above sea level will the hot air balloon be after 16 minutes?
Answer:
2344ft
Step-by-step explanation:
you have a base height of 1800ft and you know that the balloon rises 34 feet every minute. just multiply the number of minutes by 34 and add 1800.

Answer:
The answer is letter B.
With the coordinates (0, 1) ( 1, 4) (2, 7), Option B has a line of best fit represented by y = 3x + 1.
What is a linear equation?A linear equation is an equation that has the variable of the highest power of 1. The standard form of a linear equation is of the form Ax + B = 0.
The given linear equation is
y = 3x + 1
We need to find Which scatterplot represents the most likely line of best fit.
We will use the hit and trial method,
Let x = 0

y = 1
Put x = 1
y = 3 + 1
= 4
Put x = 2

The scatter plot shows a hiker's elevation above sea level over time. The equation of the trend line shown is y = 8.77x + 686. To the nearest whole number, predict what the hiker's elevation will be after 2 hours and 25 minutes.
Answer:
707 feet above sea level
Step-by-step explanation:
2 hours and 25 minutes is about 2.4167 hours.
Therefore:
y=8.77x+686
y=8.77(2.4167)+686
y=21.1944+686
y=707.1944
So the hiker's elevation will be approximately 707 feet above sea level

√ x+5 = x+3
9514 1404 393
Answer:
x = -1
Step-by-step explanation:
A graphical solution can avoid extraneous solutions. The attachment shows the one solution is x = -1.
__
Squaring both sides gives ...
x +5 = (x +3)² = x² +6x +9
Putting this in standard form, we have ...
x² +5x +4 = 0
(x +1)(x +4) = 0 . . . . . factor
x = -1 or -4 . . . . . . . . values of x that make the factors zero
__
Since we require the root to be non-negative, we must have ...
x +3 ≥ 0
x ≥ -3
The only solution that satisfies this requirement is x = -1. The solution x = -4 is extraneous. The solution is x = -1.
