Answer:12 out of 9 chances

Step-by-step explanation:

Answer: 9/24 or 3/8(simplified).

Step-by-step explanation:

Okay first let's break it down.

The spinner has a 1/4 chance of landing on blue.

The spinner has a 1/2 chance of landing on red.

The spinner has a 1/4 chance of landing on green.

The spinner has a 3/4 chance of landing on red or blue

The spinner has a 3/4 chance of landing on red or green.

The spinner has a 1/2 chance of landing on blue or green.

A 6-sided die has a 1/2 chance of landing on either even or odd.

The question first asks the probability of spinning a red or blue.

So first, you need to know how many parts of the spinner of the four sections are red and blue. It's 3/4. There are 3 even numbers on a six-sided die so that's 3/6 or 1/2. Next, multiply these probabilities to get 9/24 or 3/8.

Answer:

8.625 feets²

Step-by-step explanation:

Based on measurement illustrated in the attached picture :

There are two rectangles and one triangle :

Area of first rectangle :

Area = Length * width

Length = 1.5 ft ; width = 2.5 ft

Area = 1.5 * 2.5

Area = 3.75 ft²

Area of triangle = 1/2 * base * height

Base = 1.5 ; height = 1.5

Area = 1/2 * 1.5 * 1.5

Area = 1.125 ft²

Area of second rectangle :

Area = Length * width

Length = 1.5 ft ; width = 2.5 ft

Area = 1.5 * 2.5

Area = 3.75 ft²

Total area :

(3.75 + 3.75 + 1.125) feets

= 8.625 feets²

Answer:

an equivalent expression: -14(-8x+12y)=112x-168y

factor of an equivalent expression: 36a−16=4(9a-4)

100% of 60 = 60

100%=60

140% of 60 = x

140%=x

60/x = 100/140

(cross multiplication)

x = 84

140% of 60 = 84

Answer:

25%

Step-by-step explanation:

125 - 100 = 25

25 / 100 = 0.25

0.25 * 100 = 25%

https://www.gstatic.com/education/formulas2/355397047/en/slope_of_a_line.svg

Step-by-step explanation:

To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points.

Answer:

cmon bro is not that hard

Step-by-step explanation:

Answer:

1/3

Step-by-step explanation:

So remember slope is y/x.

THe y value is 1st y minus 2nd y. In this case 6-4.  This gets you 2

The x value is 1st x minus 2nd x. In this case 8-2. This gets you 6

Put the y and x value into your fraction(y/x) and you get 2/6.

This can be simplfyied as 1/3

Answer:

IQR = 20

Step-by-step explanation:

Quartile 1 = 25

Quartile 3 = 45

To find the interquartile range, take Q3 from Q1

45 - 25 = 20 .

Answer:

I think it is 8.8 yards because its not bigger than 10 and not smaller than 6

Answer:oh it is - 5 I had this in my questions for homework

Step-by-step explanation:you have to multiply and subtract and do that many times

Answer:

1) x = 30

2) x = 11.6

Step-by-step explanation:

1) 2x = 4x - 60   (vertical angles are equal)

subtract 4x from each side of the equation:

-2x = - 60

divide both sides by -2:

x = 30

2) 7x + 16 + 3x + 48 = 180°   (supplementary angles add up to 180°)

combine like terms:

10x + 64 = 180

subtract 64 from both sides of the equation:

10x = 116

divide both sides by 10:

x = 11.6

Answer:

1/3 divided by 3/4 = 0.44

Answer:

y = -28

Step-by-step explanation:

y=-4x

Let x=7

y = -4*7

y = -28

Answer:

8.00

Step-by-step explanation:

to find the median, you have to order all your numbers from least to greatest (6.00, 7.00, 8.00, 8.00, 9.00) then find the number in the MIDDLE. that number would be 8.00 so therefore the median is 8.00.

Answer:

16 cm squared

Step-by-step explanation:

8cm x 2cm would equal 16 cm squared

my day was okay. Had school, played some games, did hw, normal stuff. :D

Anywho im going to do my tutor hw and maybe help some other people. Bye!

Answer:

14 cm^2

Step-by-step explanation:

First of all we have to find the total area

total area = lenght x width = 8 x 2 = 16 cm^2

the shaded area is a right triangle

the area of a right triangle is

A = (leg 1 x leg2)/2 = (2 x 2)/2 = 2 cm^2

now we have to subtract it from the total area

16-2 = 14 cm^2

Answer:

4 selections

Step-by-step explanation:

We are told in the question that:

Josie selected 6 books from the library. However, he can only check out 4 books at a time.

The number of possible selections can he make is 4 selections. This is because, He can only take 4 books out of the library at a time. This is the standard.

here you go i hope this help u

Answer:

1) D. [tex]y = -\frac{3}{2}\cdot x^{12} -7\cdot x^{5}+\frac{2}{3}\cdot x -10[/tex]

2) E. The coefficient of [tex]x[/tex] is -16.

Step-by-step explanation:

1) A polynomial is an algebraic expression of the form [tex]p(x) = \Sigma \limits_{i = 0}^{n} c_{i}\cdot x^{i}[/tex], where [tex]n[/tex] is the grade of the polynomial. In this case, the only equation that satisfies this definition is:

[tex]y = -\frac{3}{2}\cdot x^{12} -7\cdot x^{5}+\frac{2}{3}\cdot x -10[/tex]

Correct answer: D

2) Let [tex]p(x) = (2\cdot x + 1) \cdot (5\cdot x^{3}-8\cdot x +4)[/tex], we proceed to expand the expression by algebraic means:

[tex]p(x) = (2\cdot x + 1)\cdot (5\cdot x^{3}) -(2\cdot x +1)\cdot (8\cdot x) + 4\cdot (2\cdot x + 1)[/tex]

[tex]p(x) = 10\cdot x^{4}+5\cdot x^{3}-16\cdot x^{2}+4[/tex]

We see that coefficients for [tex]x^{2}[/tex] and [tex]x[/tex] are -16 and 0, respectively. Hence, the incorrect answer is E.

Answer: 30

Step-by-step explanation:

the formula for the area of a triangle is base times height divided by 2

A=bh/2

the base in this triangle is 15 and the height is 4

(15)(4)/2

60/2

30

Answer:

No

Step-by-step explanation:

Originally:

48:42

If some leave and some arrive = 10:11 given in question

So 48- 8 leave = 40 women

Therefore 42+2=44

Now the ratio is 40:44 (Actual amount of people)

When you simplify/ divide by 4 = 10:11

Total amount of people is 40+44= 84 which is less than 90
