this table shows how many sophomores and juniors attended two school events. what is the probability that a randomly chosen person from this group is a junior? round your answer to two decimal places.
Probabilities are used to determine the chances of an event. Here, we want to calculate the chances of selecting a junior student. The probability of selecting a junior is 0.44.
From the table, we have:
[tex]Junior = 60[/tex]
[tex]Total = 137[/tex]
So, the probability of Junior is
[tex]P(Junior) = \frac{Junior}{Total}[/tex]
This gives:
[tex]P(Junior) = \frac{60}{137}[/tex]
[tex]P(Junior) = 0.437[/tex]
Approximate
[tex]P(Junior) = 0.44[/tex]
Hence, the probability of selecting a junior is 0.44

NEED ASAP! On a math test a student, Sarah, has to identify all the coefficients and constants of the expression 7m+6+b. Sarah say that 7 is a coefficient and 6 is a constant. Identify all the coefficients and constants of the expression. What error might Sarah have made?
Answer:
7 and 1 are coefficients
Step-by-step explanation:
7 is next to m so it is a coefficient and 1 is a coefficient of b although you can not see it we already know it has a coefficient. 6 is a constant

HCF of 50 and 90.find the answer plssss
Answer:
Step-by-step explanation:
The factors of 50 are 1,2,5,10,25,50;
The factors of 90 are 1,2,3,5,6,9,10,15,18,30,45,90.
So, as we can see, the Greatest Common Factor or Divisor is 10, because it is the greatest number that divides evenly into all of them.
The sum of two numbers is 51 and the greater number is twice the smaller number. Find the numbers. a) set up the variables Let _______ represent the first number Then _______ will represent the second number. b) What is the equation that represents the above situation? c) Solve the equation.
Answer:
34 and 17Step-by-step explanation:
a) set up the variables
Let x represent the first number Then y will represent the second number.
b) What is the equation that represents the above situation?
x = 2yx + y = 51c) Solve the equation.
Substitute x in the second equation and solve for y:
x + y = 512y + y = 513y = 51y = 51/3y = 17Then find x
x = 2y = 2*17 = 34Answer:
[tex]\tt{34~and ~17 }[/tex]
Step-by-step explanation:
let the first number is =x
second number is =y
The sum of two numbers is 51 =x+y=51•••{1}
the greater number is twice the smaller number= x=2y••••••••{2}
According to the question,
[tex]\bold{ x+y=51 }[/tex]
[tex]\bold{2y+y=51 }[/tex] [tex]\because{ (x=2y ) }[/tex]
[tex]\bold{ 3y=51 }[/tex]

3.
Write the
equation.
Slope:
riset
Run
y intercept:
equation: y=mx+b;
Answer: y = 1/4 x – 4
OR y = x/4 –4
m is the slope. b is the y-intercept.
Without numbers on the x and y axis, it may not be correct. But assuming a normal scale, the slope is positive 1/4 and the y-intercept is -4
Step-by-step explanation: To find the slope, m, determine "rise over run"
Look for places where the graphed line crosses the grid at intersections. There seems to be such places at (–4,–5), (0,–4) and (4,–3)
The "rise" is the difference in y-values. Here, they increase by 1.
The "run" is the difference in x-values. Here they increase by 4.
So the slope is 1/4. Put that in place of m.
The graphed line crosses the y-axis at –4
That is the y-intercept. Use -4 in the place of b
Keep the y and x; substitute the values for m and b we found.
y = 1/4 x – 4
OR
y = x/4 – 4 This makes it clear that x is not in the denominator of the fraction, 1/4, and in calculations with given coordinates, the value of x will be divided by 4.

there are 800 ppl who 50% of them use english 30% use spanish 15% vianameese 5% other
how many people use each language?
(WORK whoever shows the best work gets brainiest reported if no work!)
Answer:
400 people english, 240 spanish, 120 vietnamese and 40 other
Step-by-step explanation:
50% is half of 800.
half of 800 is 400. 400 use english
to find 10 percent, you divide by 10. to find 30, you multiply that by 3.
80 times 3 is 240. 240 use spanish.
15 percent is 10 percent, which is 80, +40 because of the 5 percent
80+40 is 120. 120 use vietnamese.
5 percent is half of ten percent.
half of 80 is 40.
and it all adds up to 800
your welcome!:)
Answer:
English of the bat is just 400, because that is the half of 800
spanish - 240
vianameese - 120
other - 40
Step-by-step explanation:
to get the answered you just turn the percent into a decimal like 50%-0.5, 30%-0.3, 15%-0.15, and 5%- 0.05. Then you just multiply the decimal by 800. And the number you get is the amount of people!

The Median of the data 78,56,22,34,45,54,39,68,54,84
Answer:
54
Step-by-step explanation:
The Median of the data 78,56,22,34,45,54,39,68,54,84
Median of a data is the value at the middle after rearrangement
Rearrange in ascending 0rder
22, 34, 39, 45), 54, 54, (56, 68, 78, 84
The two numbers at the middle are 54 and 54
Median = 54 + 54/2
Median = 108/2
Median = 54
Hence the median of the data is 54
Byron and Cari are best friends. Byron wants to give a collage photo frame to Cari on her birthday. He measures the photo frame at 12 inches by 18 inches. He wants to cover the edge of the photo frame with a golden ribbon at a cost of $0.50 per inch. How much ribbon will Byron need, and how much will it cost for him to cover the frame? DO NOT PUT UNITS IN THE ANSWER.
Answer:
216 inches of ribbon is needed.
216 inches of ribbon will cost Bryon $108.
Step-by-step explanation:
multiply 12 x 18
12 x 18 = 216
216 inches of ribbon need to be used to cover the frame.
To find the cost multiply 216 and 0.5
216 x 0.5 = 108
It will cost Bryon $108 for 216 inches of ribbon.

Answer:
2 3/20 mStep-by-step explanation:
The area is the product of the length and width
The area = 7 1/6 m² = 43/6 m²The length = 3 1/3 m = 10/3 mWidth = ?
A = lww = A/lw = 43/6 ÷ 10/3 = 43/6 × 3/10 = 43/20 = 2 3/20 mThe width is 2 3/20 m
Ratios and unit rates are the same things. True or false?
Answer:
a unit means that we have one of something the unit rate means we have a rate for one or something we write the rate as a ratio with a denominator of 1
so false
Answer:A rate is a comparison of two different quantities with different units, one is generally time. Rates are always ratios, since they are comparing two different numbers as they compare two different quantities. Ratios are sometimes rates, but not always; we can compare different numbers without comparing measurements.

Today Olivia has $127 in her savings account. She will deposit $5 into the account each week given x < 0 whitch function represents the amount in Olivias savings account after x weeks
Answer:
y = 127 + 5x
Step-by-step explanation:
Today Olivia has $127 in her savings account. She will deposit $5 into the account each week given x < 0
Let x = number of weeks Olivia deposits money.
y = Total pint of money that Olivia has in her account after x weeks
Hence, the function represents the amount in Olivias savings account after x weeks is ;
y = $127 + $5 × x
x < 0
y = 127 + 5x

Write an equation of the line that passes (-3,3) and is perpendicular to the line 2y=8x-6
Answer:
2y=8x-30 or -4x+y=-15
Step-by-step explanation:
Answer: y = (-1/4)x + 9/4
Step-by-step explanation:
2y = 8x - 6
So, y = 4x - 3 (Slope = 4)
Slope of perpendicular line = -1/4
Equation of line: y-3 = (-1/4)(x-(-3))
y-3 = (-1/4)x - 3/4
y = (-1/4)x + 9/4
