5.The data in the line plot show how many pages each student read last night. Which is the best measure of variability?
A)interquartile range
B)mean
C)median
D)range

Answer:

D

Step-by-step explanation:

Subtract 30 and 16. Cross out 0 and make it a 10 and 10-6= 4 then take 1 from 3 and make it a 2 and 2-1=1. It will all equal up to 14!

Answer:

8x+30+4x+18=180

12x+48=180

180-48=12x

132=12x

x=132/12

x=11

[tex]d) 3\sqrt{2}[/tex]

Step-by-step explanation:

Answer:

Step-by-step explanation:

Formula: [tex]a^{2} + b^{2} = c^{2}[/tex]

A.)

[tex]a^{2} + b^{2} = c^{2}[/tex]

[tex]4^{2} +3^{2} = c^{2}[/tex]

16 + 9 = [tex]c^{2}[/tex]

25 =  [tex]c^{2}[/tex]

5 = c

__________________________________________________________

B.)

[tex]15^{2} + 8^{2} = c^{2}[/tex]

225 + 64 = [tex]c^{2}[/tex]

289 = [tex]c^{2}[/tex]

17

__________________________________________________________

C.)

[tex]11^{2} + 14^{2} = c^{2}[/tex]

121 + 196 = [tex]c^{2}[/tex]

317 = [tex]c^{2}[/tex]

17.8

__________________________________________________________

D.)

[tex]3^{2} + 3^{2} = c^{2}[/tex]

9 + 9 = [tex]c^{2}[/tex]

18 = [tex]c^{2}[/tex]

Answer:

m∠B = 170°

Step-by-step explanation:

Sum of all angles in quadrilateral is 360°:

m∠A + m∠B + m∠C + m∠D = 360°

m∠B = 360° - m∠A - m∠C - m∠D

m∠A = 90°

m∠B = m∠D= 50°

m∠B =  360° - 90° - 50° - 50° = 170°

Answer:

[tex]m\angle BYP=42^\circ[/tex]

Step-by-step explanation:

Lines and angles

The figure shows three lines forming two angles BYP and PYH whose measures add up to 90° because it's marked as a right angle.

[tex]m\angle BYP+m\angle PYH=90^\circ[/tex]

We are given the acute angles as a function of m. thus:

5m + 98 + 2m + 48 = 90

Simplifying:

5m + 146 = 90

5m = -56

m = -56/5 = -11.2

m = -11.2°

To find the measure of angle BYP, substitute m in

5m + 98 = 5*(-11.2) + 98 = 42°

[tex]m\angle BYP=42^\circ[/tex]

Answer:

To find a vector parallel to B, such vector must be a scalar multiple of B.

Step-by-step explanation:

Two non-zero vectors are parallel if they are scalar multiples of one another.

A vector parallel to B must be a scalar multiple of B.

let the vector parallel to B be A, then their scalar multiple is given as;

A = kB

A = k(-2, 3)

where;

k is scalar

Thus, to find a vector parallel to B, such vector must be a scalar multiple of B.

Answer: 3:7

Step-by-step explanation:

There are 3 stars for every 7 circles, thus the ratio is 3:7.

Answer:

3 : 7.

Step-by-step explanation:

For every 3 stars, there are 7 circles. If 3 stars is written first, you'll need to write 3 first in your answer, and 7 second.

This is what it would look like: 3 : 7

With ratios, you could also write,

3 to 7

or

3 / 7

But 3 : 7 is most common :)

Answer:

  x = 90 degrees

Step-by-step explanation:

There are several ways to go about this (as is often the case with math problems). Here, we'll use the fact that an inscribed angle is half the measure of the arc it intercepts.

  arc DE = 2×∠DFE = 60°

  arc EF = 2×∠ECF = 60°

  arc CF = 2×∠CEF = 60°

Then arc DEC is ...

  arc DEC = arc DE +arc EF +arc FC = 60° +60° +60° = 180°

Angle DBC is half the measure of this arc, so is ...

  ∠DBC = 180°/2 = 90° = x

Answer:

[tex]\frac{1}{4}[/tex]

Step-by-step explanation:

We name the coins coin 1 and coin 2 for the sake of simplicity.

There are four possible situations:

coin 1 head, coin 2 head

coin 1 head, coin 2 tails

coin 1 tails, coin 2 head

coin 1 tails, coin 2 tails

Only case 1 results in both 'heads'. So the probability is 1/4.

Answer:

A

Step-by-step explanation:

A fraction exponent can be represented using a radical. The base number is the number in the radical. The numerator of the fraction is the exponent inside the radical. The denominator is the type of radical.

To write an exponent in radical form , the denominator, or index goes in front of the radical, and the numerator goes inside of the radical. We raise the base to the power of the numerator

Step-by-step explanation:

965-541=424

round to the nearest ten and you get 420

i hope this helped, please mark this as brainliest! thanks

Answer:

The answer is 420

Step-by-step explanation:

You first do the equation 965 - 541. The answer to that is 424, but when you round it to the nearest ten, the answer would be 420.

distribute

5y + (-3 * y) + (-3 * 2)

simplify

5y -3y + ( -3 * 2)

5y - 3y + ( -6)

5y - 3y - 6

combine like terms
