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.

Answers

Answer 1

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

Answer:

t = 4°

Step-by-step explanation:

As in any triangle, the sum of angles is 180°.

17t + 16t + 12t = 180°

45t = 180° . . . . . collect terms

t = (180/45)° . . . . divide by the coefficient of t

t = 4°

The leadership class starts a campaign to change the school mascot. The school principal has agreed to change the mascot if two-thirds of the student body plus 1 additional student vote for the change. The required number of votes is 255. How many students attend the school? (Please also write the equation)

Answers

Answer:

254/2=127

127*3=381

381+1=382

Step-by-step explanation:

254/2 because 2/3 of the students is 254 and this is to simplify it

127*3 because 127 is 1/3 of the total number of students so 127*3 would be 3/3 of the students or all of them

381+1 because we had to take out 1 of the students because there was an aditional vote so we add him back in

The Answer Is: 382

Equation: (254/2)*3+1

What is the equation of the line that passes through the point (-5, -2) and has a
slope of -6/5

Answers

Answer:

Step-by-step explanation:

you are given the slope m = -6/5 and one point (x1,y1) as (-5,-2)

next use the point-slope formula [y-y1 = m(x-x1) ] and plug in the point and the slope

y-(-2) = -6/5(x-(-2)) ( they are making this tuff with all the minus signs :/ )

y+2 = -6/5(x+2) ( nice looks better, distribute the -6/5 )

y + 2 = -6/5x -12/5 (move the 2 over )

y = -6/5x - 12/5 -2 ( 2 = 10/5 )

y = -6/5x -12/5 - 10/5 (add the fractions )

y = -6/5x -22/5

that's in the form of the slope-intercept now [ y = mx + b ] so you're done :)

Solving two-step inequalities is much like solving two-step equations. Use
inverse operations to
solve each of the following inequalities.
5x + 8.5 > - 10.3
2x - 10 < 80

Answers

Answer:

1) x>-3.76 2) x<45

Step-by-step explanation:

1) 5x+8.5>-10.3

Isolate the variable

Combine like terms/ subtract 8.5 from both sides

5x>-18.8

Divide by sides by 5

x>-3.76

Remember, if we were dividing or multiplying by a negative number, we would switch the inequality sign, but here we do not.

2) 2x-10<80

Isolate the variable

Combine like terms/ add 10 to both sides

2x<90

Divide both sides by 2

x<45

The possible combination of sides of triangles is

(2 + 3) >4(3 + 4)> 5(5+ 6)>7What is Property of Triangle?

In a triangle, the third side must be greater than or equal to the sum of the other two sides. The length of a triangle's third side is always longer than the sum of any two of its sides.

Given sides are 2 inches, 3 inches, 4 inches, 5 inches, 6 inches, and 7 inches.

We know that the third side of a triangle is greater than sum of other two sides.

So, (2 + 3) >4

and, (3 + 4)> 5

and, (5+ 6)>7

Hence, the possible combination of sides of triangles is

(2 + 3) >4(3 + 4)> 5(5+ 6)>7

ABC congruent DEF find the measure of the given angles or the lengths of the given sides

Answers

Answer:

BC = 8 and EF = 8

Step-by-step explanation:

Congruent triangles have equal angles, equal sides, equal perimeters, and equal areas.

Let us solve the question

∵ The two triangles ABC and DEF are congruent

∴ BC = EF

∵ BC = 3z + 2

∵ EF = z + 6

→ Equate their length

∴ 3z + 2 = z + 6

→ Subtract z from both sides

∵ 3z - z + 2 = z - z + 6

∴ 2z + 2 = 6

→ Subtract 2 from both sides

∵ 2z + 2 - 2 = 6 - 2

∴ 2z = 4

→ Divide both sides by 2

∴ z = 2

→ Substitute z by 2 in the length of sides BC and EF to find them

∵ BC = 3(2) + 2 = 6 + 2

∴ BC = 8

∵ EF = 2 + 6

∴ EF = 8

The missing angle U is 86°, the value that makes the total be 360°. Then the top two angles total 180°, as do the bottom two angles. This means sides SV and TU are parallel, but sides UV and ST are not.

The figure has one pair of parallel sides, so is a trapezoid.
