Probability helps us to know the chances of an event occurring. The correct option is A.

<h3>What is Probability?</h3>

Probability helps us to know the chances of an event occurring.

$\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}$

Dependent events are those events in which the outcome of the first event affects the outcome of the second event. The statement that is correct about the dependent event is that the probability of all dependent events can be calculated using the "OR" formula P(A+B) =P(A) +P(B)-P(A and B).

Hence, the correct option is A.

Answer:

For a trapezium of height H, parallel side 1 X, and parallel side 2 Y, the area is:

A = (1/2)*H*(X + Y)

with this we can complete the table.

Here we know:

X = 7cm

Y = 11cm

H = 6cm

Then: A = (1/2)*6cm*(7cm + 11cm) = 54 cm^2

Here we know:

X = 8 m

Y = 10 m

A = 126 m^2

Then:

126 m^2 = 0.5*H*(8m + 10m)

126 m^2 = H*9m

126 m^2/9m = H = 14m

Then the height of this trapezoid is 14m

Here we know:

X = 5mm

H = 8mm

A = 72 mm^2

Then:

72 mm^2 = 0.5*8mm*(5mm + Y)

72 mm^2 = 4mm*(5mm + Y)

72mm^2/4mm = 5mm + Y

18 mm = 5mm + Y

18mm - 5mm = Y

13 mm = Y

Then the parallel side 2 is 13 mm long.

Jim wants to build a toy house. He plans for the width to be 2 feet and the length to be 3 feet. Then he decides to add to the l

Cloud [144]

Lets w width, l length, y amount add, A area, P perimeter

A=lw=(3+y)(2)=6+2y ft²

p= 2l+2w= 2(3+y)+2(2)= 6+2y+4 =10+2y

Complete Question

Grandpa and Grandma are treating their family to the movies. Matinee tickets cost $4 per child and $4 per adult. Evening tickets cost $6 per child and $8 per adult. They plan on spending no more than $80 on the matinee tickets and no more than $100 on the evening tickets. Could they take 9 children and 4 adults to both shows? Show your work. A yes or no answer is not sufficient for credit.

Answer:

Yes it is possible to take the 9 children and 4 adults to both shows

Step-by-step explanation:

From the question we are told that

The cost of the Matinee tickets for a child is z = $4

The cost of the Matinee tickets for an adult is a = $ 4

The cost of the Evening tickets for a child is k = $6

The cost of the Evening tickets for an adult is b = $8

The maximum amount to be spent on Matinee tickets is m = $80

The maximum amount to be spent on Evening tickets is e = $100

The number of child to be taken to the movies is n = 9

The number of adults to be taken to the movies is j = 4

Now the total amount of money that would be spent on Matinee tickets is mathematically evaluated as

$t = 4 n + 4 j$

substituting values

$t = 4 * 9 + 4* 4$

$t = 52$

Now the total amount of money that would be spent on Evening ticket is mathematically evaluated as

$T = 6n + 8j$

substituting values

$T = 6(9) + 8(4)$

$T = 86$

This implies that it is possible to take 9 children and 4 adults to both shows

given that

$t \le m$

i.e $56 $\le$ $ 80

and

$T \le e$

i.e $ 86 $\le$ $ 100

What’s the answer ???

Angle 1 and angle 2 are corresponding angles. Notice how they are in the upper right hand corner of each 4-corner angle configuration. In other words, they are both above their respective parallel line and on the right side of the transversal. So that's why they correspond to one another.

Because the horizontal lines are parallel, this means the corresponding angles are congruent. So angle 1 is congruent to angle 2
