Ana has a bag of skittles. The number of skittles and the different colors of the skittles are listed: 8 red , 6 blue , 3 green , 6 yellow Ana will choose two skittles at random. What is the probability that Ana chooses a blue skittle first, eats it, and then selects a skittle that is not yellow?
Answer:
The probability of her not choosing yellow is 6/22.
Step-by-step explanation:
The probability that she chooses a blue skittle is 6/23 since she eats one blue skittle the total decreases to 22. So the probability of her not choosing yellow is 6/22

This cone and sphere have equal volumes.
What is the radius of the sphere?
Answer:
the radius of the sphere is 12 cm.
Step-by-step explanation:
IN A CONE
vertical height (h) = 27 cm
radius (r) = 32 / 2 = 16 cm
Now the volume of cone is
= 1/3 *h*π*r²
= 1/3 * 27 *π *16²
= 2304π cm³
Also by the question the cone and the sphere have equal volumes so
volume of sphere = volume of cone
= 2304 π cm³
OR, 4/3 πr³ = 2304 π
4/3 * r³ = 2304
r³ = 2304 * 3 / 4
r³ = 1728
r = ∛1728
r = 12 cm

Write a formula for the given measure. Let P represent the perimeter in inches, and w represent the width in inches. Identify which variable depends on which in the formula.
Complete Question:
Write a formula for the given measure. Let P represent the perimeter in inches, and w
represent the width in inches. Identify which variable depends on which in the formula.
*The perimeter of a rectangle with a length of 5 inches
Answer:
P = 2(5 + w)
Or
P = 20 + 2w
P is the dependent variable
w is the independent variable
P depends on w.
Step-by-step explanation:
Given:
Perimeter of rectangle = P
Width of the rectangle = w
Length of the rectangle = l = 5 in.
Formula for perimeter of a rectangle = 2(length + width)
Plug in the values. Formula for the given measure would be:
P = 2(5 + w)
Or
P = 20 + 2w
P is the independent variable, while w is the dependent variable.
This is because the Perimeter (P) of the rectangle is dependent on the width (w). Whatever value of w we get would determine the value of P were would get. Therefore,
P depends on w.

Match the graph with its equation.
A. –6x – 2y = 12
B. –6x + 2y = 12
C. 6x + 6y = 12
D. 6x + 2y = 12
Answer:
The answer is A. -6x-2y=12.
Step-by-step explanation:
In order to graph the equation, start by rewriting the equation in slope-intercept form. To rewrite the equation in slope-intercept form, add 6x to both sides of the equation, and then divide each term by -2 and simplify. Now, the equation should look like y= -6-3x.
Using the slope-intercept form, you can find the slope and y-intercept. By using the formula of y= mx+b, m= -3 and b= -6. Thus, the slope is -3 and the y-intercept is (0,-6).
Now, you can create a table of x and y values to graph the equation. After graphing the table of x and y values, the final answer is -6x-2y=12.

The scale of a map is 0.5 inches :10 km. Find the actual distance corresponding to the map distance of 10 inches.
Answer:
200 km
Step-by-step explanation:
Create a proportion where x is the actual distance:
[tex]\frac{0.5}{10}[/tex] = [tex]\frac{10}{x}[/tex]
Cross multiply and solve for x:
0.5x = 100
x = 200
So, the actual distance is 200 km

line cd in DE are tangent to circle a shown below ifCE is 130° what is the measure of angle CDE
20°
40°
42.5°
50°
Answer:
m<CDE = 50°
Step-by-step explanation:
Recall: when an angle is formed outside a circle by two tangents, the angle formed = ½(the difference between the measures of the intercepted arcs), based on the outside angles theorem.
This implies that:
m<CDE = ½(Arc CBE - Arc CE)
Arc CE = 130°
Arc CBE = 360° - 130° = 230°
Plug in the values
m<CDE = ½(230 - 130)
m<CDE = ½(100)
m<CDE = 50°
The measure of angle m<CDE is 50 degrees
Circle geometryFrom the diagram shown, the angle at the vertex is equal to half the difference of the angles at the intercepted arc.
Given
Angles at the arcs are 130 and 230 (360 - 130)Angle at the vertex = m<CDEm<CDE = 1/2(230-130)
m<CDE = 1/2(100)
m<CD = 50 degrees
Hence the measure of angle m<CDE is 50 degrees

A public health expert is worried that a recent outbreak of a disease may be related to a batch of spinach from a certain farm. She wants to test the plants at the farm, but it will ruin the crop if she tests all of them.If the farm has 5,000 spinach plants, describe a method that would produce a random sample of 10 plants.Why would a random sample be useful in this situation?
Answer: Systematic Random Sample
Step-by-step explanation:
Based on the information given, the method that would produce a random sample of 10 plants is the systematic random sample.
Systematic sampling is referred to as a probability sampling method whereby a random sample, that has a fixed periodic interval, will be chosen from the larger population. It should be noted that the fixed periodic interval, can be gotten by dividing the population by desired sample size.
In this case, since there are 5000 plants and there needs to ba a random sample of 10 plants, the fixed periodic interval will be: = 5000/10 = 500th plant. That means the 500th plant will be chosen.
