Answer:

a) You have a 30% of not drawing yellow or green

b) You'd have a 46% of frawing a red or green bead

Step-by-step explanation:

Total beads: 42 + 28 + 12 + 18 = 100

Green beads + yellow beads = 28 + 42 = 70

100 - 70 = 30

30/100 = 0.3 or 30%

Red beads + green beads = 18 + 28 = 46

46/100 = 0.46 or 46%

Answer:

1. 30%

2.46%

Step-by-step explanation:

The probability of Kayla not drawing a yellow or a green bead is 30 %. The probability of Kayla drawing a red or a green bead is  46 %.

Correct for plato! :)

Answer:

The answer is n = 13

Step-by-step explanation:

1) Divide both sides by 3.

[tex] \frac{3}{24} = n - 5 [/tex]

2) Simplify 24/3 to 8.

[tex]8 = n - 5[/tex]

3) Add 5 to both sides.

[tex]8 + 5 = n[/tex]

4) Simplify 8 + 5 to 13.

[tex]13 = n[/tex]

5) Switch sides.

[tex]n = 13[/tex]

Therefor, the answer for this equation is n = 13.

Answer:

y = -1, x = -2

Step-by-step explanation:

First, multiply the top equation by 2 to make 3x become 6x:

6x - 8y = -4

Second, multiply the bottom equation by 3 to make -2x become -6x:

9y - 6x = 3

Add the two equations together, and you get:

y = -1

Plug in y as -1 into the first or second equation:

3x - 4(-1) = -2

OR

3(-1) - 2x = 1

x = -2

Answer:

Step-by-step explanation:

let tacos be x and burritos be y

4.5x+7.75y = 519.25

It says there were twice as many tacos sold as there were burritos sold

Therefore, y = 2x

Substituting this in the above equation: 4.5x + 7.75*2x = 519.25

4.5x+15.5x = 519.25

x = 519.25/20

x = 25.9625

We will use the Pythagorean Theorem:

[tex] {17}^{2} = {8}^{2} + {x}^{2} \\ 289 = 64 + {x}^{2} \\ {x}^{2} = 289 - 64 \\ {x}^{2} = 225 \\ x = \sqrt{225} \\ x = 15[/tex]

Step-by-step explanation:

It took 3 hours for it to go from 78 to 72.

Which is a rate of -2 degrees per hour

We want to know what the temperature was two hours before it was 78 degrees so we'd do 78 - (-2) which is 82

Null Hypothesis = Depression levels among two groups equal, Alternate Hypothesis = Depression levels among two groups unequal.

Step-by-step explanation:

Null Hypothesis is the neutral hypothesis, of no difference.

Null Hypothesis in this case is, mean depression level among victims = mean depression level among bystanders.

Alternate Hypothesis in this case is, mean depression level among victims ≠ mean depression level among bystanders.

Step-by-step explanation:

Let's define what we have:

Conner's morning temperature: 101.2 degrees

Conner's last night temperature: morning temperature + 0.7 degrees

We know that Conner's last night temperature is addition because it was higher (key word) than the morning temperature.

Therefore, we simply add the values together to get our answer:

101.2 + 0.7 = 101.9 degrees

Answer:

Step-by-step explanation:

The sum of the measures of the exterior angles of a convex polygon is always 360°. If each is 60°, there are 360°/60° = 6 of them.

There are 6 sides.

The adjacent interior angle is the supplement of the exterior angle, so is ...

  180° -60° = 120°.

Each interior angle measures 120°.

Answer:

- 9

Step-by-step explanation:

18÷x = −2

18 = −2x

-2x = 18

x = 18 ÷ - 2

x = - 9

Answer:

y = 1

Step-by-step explanation:

-3y + 14 + y = 12

-3y + y + 14 = 12

-2y + 14 = 12

-2y + 14 - 14 = 12 - 14

-2y = -2

-2y/-2 = -2/-2

y = 1

Answer:

y=1

Step-by-step explanation:

Hey There!

So to solve this type of problem we use inverse operations

-3y+14+y=12

step 1 subtract 14 from each side

14-14

12-14=-2

now we have

-3y+y=-2

step 2 combine like terms

-3y+y=-2y

now we have -2y=-2

step 3 divide each side by -2

-2/-2=1

so we can conclude that y=1

Answer:

The angular speed of a point on Earth is

π12

radian per hour. The Equator lies on a circle of radius approximately 4000 miles. Find the linear velocity, in miles per hour, of a point on the Equator.

Step-by-step explanation:

They are 31.68 miles apart.

The formula to measure the length of the arc is – Arc Length Formula (if θ is in degrees) s = 2 π r (θ/360°)

Arc Length Formula (if θ is in radians) s = ϴ × r.

given:

r= 3.960 miles

[tex]\theta_2[/tex] = 40.5 and [tex]\theta_1[/tex] = 32.5

We know, l = r[tex]\theta[/tex]

So, Δl = rΔ[tex]\theta[/tex]

Δl= r ( [tex]\theta_2[/tex] - [tex]\theta_1[/tex] )

Δl = 3.96 ( 40.5 - 32.5)

Δl = 3.96 x 8

Δl= 31.68 miles.

Hence, they are 31.68 miles apart.

Answer:

[tex](x + 12)^2 + (y + 7)^2 = 277[/tex]

Step-by-step explanation:

Equation of a circle:

The equation of a circle with center [tex](x_0,y_0)[/tex] is given by:

[tex](x - x_0)^2 + (y - y_0)^2 = r^2[/tex]

In which r is the radius.

Center (-12, – 7)

This means that [tex]x_0 = -12, y_0 = -7[/tex]. So

[tex](x - x_0)^2 + (y - y_0)^2 = r^2[/tex]

[tex](x - (-12))^2 + (y - (-7))^2 = r^2[/tex]

[tex](x + 12)^2 + (y + 7)^2 = r^2[/tex]

Passes through the point (-3,7).

This means that we use [tex]x = -3, y = 7[/tex] to find the radius squared. So

[tex](x + 12)^2 + (y + 7)^2 = r^2[/tex]

[tex](-3 + 12)^2 + (7 + 7)^2 = r^2[/tex]

[tex]81 + 196 = r^2[/tex]

[tex]r^2 = 277[/tex]

The equation of the circle is:

[tex](x + 12)^2 + (y + 7)^2 = r^2[/tex]

[tex](x + 12)^2 + (y + 7)^2 = 277[/tex]
