Answer:

A = 93.31 ft²

Step-by-step explanation:

The area (A) of a trapezoid is calculated as

A = \(\frac{1}{2}\) h (b₁ + b₂)

where h is the perpendicular height and b₁, b₂ the parallel bases

Here h = 6.2, b₁ = 7.8, b₂ = 14.7 + 7.6 = 22.3 , then

A = \(\frac{1}{2}\) × 6.2 × (7.8 + 22.3) = 3.1 × 30.1 = 93.31 ft²

Northside Christian Academy has 528 students enrolled this year. That is an in- crease of 10% over last year's enrollment. How many students were enrolled last year?

Let

x ------> students enrolled last year

we have that

100%+10%=110%=110/100=1.10

so

528=1.10x

solve for x

x=528/1.10

x=480

Using the Bayes' theorem, we find the probability that the transferred ball was white given that the second ball drawn was white to be 52/89, or approximately 0.5843.

To solve this problem, we can use Bayes' theorem, which relates the conditional probability of an event A given an event B to the conditional probability of event B given event A:

P(A|B) = P(B|A) * P(A) / P(B)

where P(A|B) is the probability of event A given that event B has occurred, P(B|A) is the probability of event B given that event A has occurred, P(A) is the prior probability of event A, and P(B) is the prior probability of event B.

In this problem, we want to find the probability that the transferred ball was white (event A) given that the second ball drawn was white (event B). We can calculate this probability as follows:

P(A|B) = P(B|A) * P(A) / P(B)

P(B|A) is the probability of drawing a white ball from urn b given that the transferred ball was white and is now in urn b. Since there are now six white balls and three black balls in urn b, the probability of drawing a white ball is 6/9 = 2/3.

P(A) is the prior probability of the transferred ball being white, which is the number of white balls in urn a divided by the total number of balls in urn a, or 6/13.

P(B) is the prior probability of drawing a white ball from urn b, which can be calculated using the law of total probability:

P(B) = P(B|A) * P(A) + P(B|not A) * P(not A)

where P(B|not A) is the probability of drawing a white ball from urn b given that the transferred ball was black and P(not A) is the probability that the transferred ball was black, which is 7/13.

To calculate P(B|not A), we need to first calculate the probability of the transferred ball being black and then the probability of drawing a white ball from urn b given that the transferred ball was black.

The probability of the transferred ball being black is 7/13. Once the transferred ball is moved to urn b, there are now five white balls and four black balls in urn b, so the probability of drawing a white ball from urn b given that the transferred ball was black is 5/9.

Therefore, we can calculate P(B) as follows:

P(B) = P(B|A) * P(A) + P(B|not A) * P(not A)

= (2/3) * (6/13) + (5/9) * (7/13)

= 89/117

Now we can plug in all the values into Bayes' theorem to find P(A|B):

P(A|B) = P(B|A) * P(A) / P(B)

= (2/3) * (6/13) / (89/117)

= 52/89

Therefore, the probability that the transferred ball was white given that the second ball drawn was white is 52/89, or approximately 0.5843.

Linda is currently 6 years old. According to the given information, we can write the following equation: x + 18 = 4x

Let's assume Linda's current age is x years. We are given that 18 years from now, Linda will be 4 times older than she is today.

So, 18 years from now, Linda's age will be x + 18.

Now, let's solve this equation to find Linda's current age.

Subtracting x from both sides of the equation gives us:

18 = 3x

Dividing both sides of the equation by 3 gives us:

x = 6

Therefore, Linda is currently 6 years old.

To verify our solution, we can check if 18 years from now Linda will be 4 times older than she is today:

6 + 18 = 24

4 * 6 = 24

As both sides of the equation are equal, our solution is correct.

Answer:

angle CBE=15 degrees

Step-by-step explanation:

angle ECD is 60 degrees and EC=CD because equilateral triangle

angle DCB is 90 degrees and CB=CD because square

angle ECD +angle DCB= angle ECB

60+90=150=angle ECB

since triangle ECB has legs EC and CB  equal in length, then it is an isosceles triangle.

so angles CBB and CBE are equal

angle CBE=(180-150)/2

angle CBE=15 degrees

Answer:

15 degrees

Step-by-step explanation:

Since triangle CDE is a equilateral triangle then all the sides and angles are congruent DC=CE=ED, ∠DEC=∠ECD=∠CDE=60 degrees

since line CD is also a side of the square and all sides of a square are congruent therefore DC=CB=BA=AD

therefore side BC is equal to side CE which means CBE is an isosceles triangle then angles ∠BEC and ∠CBE are congruent

Then in order to figure out angle ∠CBE we need to find ∠ECB

and ∠ECB=∠DCE+∠DCB

∠DCE= 60 degrees because it's a equilateral triangle

∠DCB=90 degrees because it's a square

therefore ∠ECB=150 degrees

all angles of a triangle = 180 degrees

∠BEC + ∠CBE + ∠ECB = 180

since ∠BEC is congruent to ∠CBE i can substitute ∠BEC for ∠CBE

2(∠CBE) + 150 =180

2(∠CBE)=30

∠CBE=15

For an event based on order by sam for ham and coffee with different probabilities, then the probability that he will order neither ham nor coffee is equals to the 0.07.

We have sam is a regular customer at joe's diner. Let us consider two events be defined as A: sam will order ham

B: sam will order coffee

Now, the probability that sam will order ham, P( A) = 0.8

The probability that sam will order coffee, P( B) = 0.65

We have to determine the probability that he will order neither ham nor coffee.

Probability is chances of occurrence of an event. It is calculated by dividing the favourable response to total possible outcomes. Probability value always lies between 0 to 1. Apply probability law P( will order ham ) + P( will not order ham) = 1

=> Probability that sam will not order ham

\(P( \bar A ) \) = 1 - 0.8 = 0.2

Probability that sam will not order coffee,

\(P( \bar A ) \)= 1 - 0.65 = 0.35

Now, as we see both events A and B are independent events so, there corresponding also independent. Therefore, Probability that he will order neither ham nor coffee, \( P( \bar A ∩ \bar B) \)

\(= P( \bar A) P(\bar B) \)

= 0.2 × 0.35 = 0.07

Hence, required probability is 0.07.

Therefore, the image is formed at a distance of approximately 46.03 cm behind the mirror, and its height is approximately 2.98 cm.

We'll use the mirror formula and magnification to find the height of the image produced by the convex mirror.
1/f = 1/do + 1/di
do = object distance = 17 cm
f = focal length = -59 cm
Now, let's solve for the image distance (di):
1/-59 = 1/17 + 1/di
1/di = 1/-59 - 1/17
1/di ≈ -0.0217
di ≈ -46.03 cm
The magnification (M) is given by:
M = -di/do
M ≈ 46.03/17
M ≈ 2.71
Now, let's find the height of the image (hi):
hi = M * object height
hi = 2.71 * 1.1
hi ≈ 2.98 cm

Therefore, the image is formed at a distance of approximately 46.03 cm behind the mirror, and its height is approximately 2.98 cm.

The probability that the sum of the rolls is divisible by 6 is 1/1296, which is approximately 0.00077 or 0.077%.

To find the probability that the sum of the rolls is divisible by 6, we need to determine the favorable outcomes and the total number of possible outcomes.

First, let's identify the favorable outcomes. In this case, the sum of the rolls can be divisible by 6 if the sum is either 6 or 12.

1. For the sum of 6:
  - One possible outcome is rolling a 6 on the first roll and rolling a 1 on the remaining four rolls.
  - Another possible outcome is rolling a 5 on the first roll and rolling a 2 on the remaining four rolls.
  - We can also have rolling a 4 on the first roll and rolling a 3 on the remaining four rolls.
  - Similarly, rolling a 3 on the first roll and rolling a 4 on the remaining four rolls.
  - Finally, rolling a 2 on the first roll and rolling a 5 on the remaining four rolls.
  - This gives us a total of 5 favorable outcomes.

2. For the sum of 12:
  - One possible outcome is rolling a 6 on all five rolls.
  - This gives us a total of 1 favorable outcome.

Now let's determine the total number of possible outcomes. Since we are rolling a fair 6-sided die 5 times, the total number of possible outcomes is 6^5 (since each roll has 6 possible outcomes).

Therefore, the probability that the sum of the rolls is divisible by 6 is:

(total number of favorable outcomes) / (total number of possible outcomes)
= (5 + 1) / (6^5)
= 6 / 7776
= 1 / 1296

So, the probability that the sum of the rolls is divisible by 6 is 1/1296, which is approximately 0.00077 or 0.077%.

The probability of selecting exactly three clubs from a standard deck is 0.088. Where n = 5; p = 0.25; q = 0.75; and x = 3 . It is calculated by using binomial probability.

The binomial probability formula is

P(X = x) = ⁿCₓ pˣ q⁽ⁿ⁻ˣ⁾ = \(\frac{n!}{(n-x)!x!} p^xq^{(n-x)}\)

Where n is the number of trials, p i is the probability of success, and q is the probability of failure.

And q = 1 - p

It is given that, a card is selected from a standard deck and replaced.

This experiment has repeated a total of five times. i.e., trials n = 5

So, the probability of success is p = 1/4 = 0.25

(Since one card is to be selected from the five trials where each time the card is replaced)

Then, the probability of failure is q = 1 - 0.25 = 0.75

And it is given that we need to find the probability of selecting exactly three clubs. So, the required random variable is x = 3.

Then, using the binomial probability formula, we get

P(X = x) = ⁿCₓ pˣ q⁽ⁿ⁻ˣ⁾

⇒ P(X = 3) = ⁵C₃ p³q⁽⁵⁻³⁾ = ⁵C₃(0.25)³(0.75)² = 0.0878
