Vincent is giving cakes to some children at a carnival. He has 2 strawberry cakes, 6 pineapple cakes, and 7 chocolate cakes. If Vincent selects a cake randomly without looking, what is the probability that he will give a pineapple cake to the first child and then a strawberry cake to the second child? (5 points)


6 over 15 multiplied by 2 over 14 is equal to 12 over 210

6 over 15 plus 2 over 14 is equal to 114 over 210

6 over 15 multiplied by 2 over 15 is equal to 12 over 225

6 over 15 plus 2 over 15 is equal to 8 over 15

Answers

2+6+7 = 15 total cakes

6 pineapple so probability is 6/15

 then there would be 14 cakes

2 strawberry for a probability of 2/14

6/15 x 2/14 = 12/210

 the first answer is the right one

Answer:

[tex]\frac{12}{210}[/tex]

Step-by-step explanation:

Strawberry cakes = 2

Pineapple cakes = 6

Chocolate cakes = 7

Total cakes = 15

Now we are given that  Vincent selects a cake randomly without looking, and he will give a pineapple cake to the first child

So, probability of getting a pine apple cake in first draw = [tex]\frac{\text{No. of pineapple cakes}}{\text{Total no. of cakes}}[/tex]

                                                                                             = [tex]\frac{6}{15}[/tex]

Now total no. of remaining cakes = 15-1 =14

Now we are given that  Vincent selects a cake randomly without looking, and he will give a strawberry cake to the second child

So, So, probability of getting a strawberry cake in second draw= [tex]\frac{2}{14}[/tex]

So,  the probability that he will give a pineapple cake to the first child and then a strawberry cake to the second child =  [tex]\frac{6}{15} \times\frac{2}{14} [/tex]

                                                                           =  [tex]\frac{12}{210}[/tex]

Hence Option A is true.

The probability that he will give a pineapple cake to the first child and then a strawberry cake to the second child is [tex]\frac{12}{210}[/tex]

which of the following best describes a regular polygon when the sum of its interior angles is 1080 degrees A.) octagon B.) heptagon C.) hexagon D.) nonagon

Answers

a) octagon

1080= (n-2)180
1080/180=6

6=(n-2)
n=8
(This is the formula for finding the sum of interior angles in polygons. n represents the number of sides in the polygon)

Answer:

Option A is correct.

Step-by-step explanation:

Given: Sum of all the interior angles of a regular polygon = 1080°

To find: number of sides or name of polygon.

We know that Sum of all interior angle of a regular polygon is given by following formula,

Sum of all angles = ( n - 2 ) × 180° ,    where n = no of sides.

⇒ 1080° = ( n - 2 ) × 180°

n - 2 = 6

n = 6 + 2

n = 8

Name of regular polygon is Regular Octagon.

Therefore, Option A is correct.

Line A: 2x + 2y = 8 Line B: x + y = 4 Which statement is true about the solution to the set of equations? It is (8, 4). It is (4, 8). There is no solution. There are infinitely many solutions.

Answers

We want to check how many intersections line A and B have, that is, we want to check how many common solutions do these equations have:

i) 2x + 2y = 8

ii) x + y = 4

use equation ii) to write y in terms of x as : y=4-x, 

substitute y =4-x in equation i):

2x + 2y = 8
2x + 2(4-x) = 8
2x+8-2x=8
8=8

this is always true, which means the equations have infinitely many common solutions.

Find the outlier of the set of data: 24, 37, 33, 31, 28, 25, 33, 12

Answers

Outlier - A value that "lies outside" than most of the other values.

The outlier is therefore 12, because it is not in the general range of values, which is on average around 29.

Answer:

The outlier of the set is 12.

Step-by-step explanation:

Consider the provided set of data:

4, 37, 33, 31, 28, 25, 33, 12

The outlier is a kind of data which is abnormal distance from the other points.

Or the data that lies outside the other value in the provided set.

Now consider the data.

12 is lies outside the other values because the distance is abnormal.

The number 12 is not close to any of the other numbers.

Hence, the outlier of the set is 12.

A regular pentagonal prism has a height of 14 in. and a base edge length of 10 in. Identify its lateral area and surface area.
Can anyone help me solve this?

Answers

The lateral faces of the prism are 5 rectangles with dimensions 10 by 14.

So the lateral area = 5 * 10 * 14 =  700 (in squared)


Consider one of the bases of the prism.

As shown in the figure, the pentagon is made up of 5 isosceles triangles.

The vertex of each of these 5 triangles is 360°/5=72°.

Draw the altitude, which forms 2 right triangles with angle measures 36°-54°-90°.
 
Let he hypotenuse be s and the altitude be h in, as shown in the figure.

x*cos54°=5

x=5/(cos54°)=5/(0.588)=8.5

then, 

h=x*sin54°=8.5*(0.8)=6.8 (in)

Thus, the area of one of the 5 congruent isosceles triangles is 

[tex] \frac{1}{2}*10*6.8= 34[/tex] (in squared)

The area of the pentagonal base is 34*5 = 170 (in squared)


Thus the surface area = lateral area + 2 base area
           = 700+2*170 = 700+340 = 1040 (in squared)


Answer: 

lateral area: 700 in squared

surface area: 1040 in squared

Answer:

L = 700 in2 ; S = 1044.1 in2

In a rain forest, it typically rains 290 days out of the year. If it rains today, what is the probability that it will rain tomorrow?

a. 72%
b. 81%
c. 79%
d. 61%

Answers

Hey there!

Since we weren't given any probabilities based on the chance of rain after it rained the day before, we can assume the probability will stay the same. We can disregard "If it rains today...". 

If it rains 290 days out of the year (365 days), there will be a 290/365 chance of rain of a particular day. You can divide 290 by 365 to get a 79% chance.

Human and non-human species possess a mental system of number representations that appear early in the lifespan and that supports approximate number skills, such as numerical estimation or number comparison. With the later acquisition of language and of symbolic numbers, human beings also develop exact number skills that allow using numbers precisely, such as in counting and arithmetic. The current review points out the behavioral data which either support or challenge these contrasting proposals. In an attempt to provide a comprehensive overview of these mixed data, we carefully took into account the heterogeneity of the available studies regarding the kind of tasks, stimuli or ages of assessment.

Which number in the monomial 215x18y3z21 needs to be changed to make it a perfect cube?
3
18
21
215

Answers

We need to remember that:
                   xyz = (x)(y)(z)
if x, y and z are perfect cubes, then xyz would also be a perfect cube

Also, 
                 (x^n)^m = x^(mn)
if it is a perfect cube, then it can be factored into the expression (x^n)^3, wherein n is a whole number.

All should be a perfect cube, given

215x^18(y^3)(z^21)

By writing the terms separately, we would see which one is to be changed. 

215 = 5*43, we see this is not a perfect cube, we could changed it to 6^3 or 216

x^18=(x^6)^3

y^3=y^3
z^21=(z^7)^3

The other terms are perfect cubes except for the first one. So the correct answer would be the last option, 215 should be changed.

Answers

1.Rita spent $26.25 on fabric.


2. I know this because...
   - First, I subtracted the cost of the ribbon from how much she paid.
        · Equation: $50.00 - $18.50 = $31.50
   
   - Second, I subtracted the change received by the reduced cost ($31.50)
       · Equation: $31.50 - $5.25 = $26.25

3. So, the final amount of money Rita spent on fabric is $26.25.
