Answer:

73

Step-by-step explanation:

[tex]8^2[/tex] is 64. [tex](7-4)^2[/tex] is the same as [tex]3^2[/tex] which is 9. 64+9=73. Here, for [tex](7-4)^2[/tex] , we can evaluate the part inside the bracket first. And 7-4=3.

Answer:

Length: 25, Width: 7

Step-by-step explanation:

Let the width be represented by w. We can then assume that the length is equivalent to 3w+4

So, we can set the equation 2(3w+4)+2(w). Simplify to 8w+8=64

Simplify the equation and solve for w, which is 7

Plug into the the length, which is 3w+4

Answer:

Length: 25 inches

Width: 7 inches

Step-by-step explanation:

Perimeter = 2L + 2W

Length: 3w + 4

Width: w

64 = 2(3w + 4) + 2w

64 = 6w + 8 + 2w

64 = 8w + 8

56 = 8w

w = 7

Length: 3(7) + 4 = 25

Width: 7

Answer:

Fatima's points = 46

Zahra's points = 30

Step-by-step explanation:

Let's give names to the unknowns (the number of points each one got)

Fatima's points = y

Zahra's points = x

Now create the equations given by the info they provide:

"Fatima got 16 marks more than Zahra"

y = x + 16

"The product of their mark is 1380."

x * y = 1380

Now use the first equation as substitution for "y" in the second equation:

x * (x + 16) = 1380

reduce the expression:

x^2 + 16 x = 1380

x^2 + 16 x - 1380= 0

Solve using quadratic formula:

[tex]x=\frac{-16+/- \sqrt{16^2+4(1380)} }{2} \\x=\frac{-16+/- \sqrt{5776} }{2} \\x=-8+/- 38\\x = 30\,\,\,or\,\,\,x=-46[/tex]

we pick 30 since the scores from a test must be larger than zero.

Now we use the first equation to solve for the other variable;

y = 30 + 16 = 46

then x = 30 and y = 46

Answer:

(i) = 85‬%

(ii) = 30%

Step-by-step explanation:

The question is a probability question.

We will need the following values:

P(A) = 60%

P(B) = 40%

P(C) = 30%

P(AnB) = 20%

p(AnC) = 10%

P(BnC) = 20%

P(AnBnC) = 5%

(i) To determine the percentage of the families in the city that subscribe to at least one of the three newspapers:

P(A) + P(B) + P(C) + P(AnBnC) - P(AnB) - p(AnC) - P(BnC)

= 60% + 40% + 30% + 5% - 20% - 10% - 20%

= 85‬%

(ii) To determine the percentage of the families in the city that subscribe to exactly one newspaper:

P(at least one paper) - p(AnB) - p(AnC) - P(BnC) -  P(AnBnC)

= 85‬% - 20% - 10% - 20% - 5%

= 30%

Answer:

26°

Step-by-step explanation:

[tex]m\angle WXZ = 78\degree... (given) \\\\

m\angle 2 = 2m\angle 1...(given)... (1)\\\\

\because m\angle 1 + m\angle 2=m\angle WXZ \\\\

\therefore m\angle 1 + m\angle 2=78\degree... (2)\\\\

\therefore m\angle 1 + 2m\angle 1=78\degree\\ [From\:equations\: (1)\: \&\:(2)] \\\\

\therefore 3m\angle 1=78\degree\\\\

\therefore m\angle 1=\frac{78\degree}{3}\\\\

\therefore m\angle 1=26\degree \\[/tex]

Answer:

48

Step-by-step explanation:

If Bao eats 12 chicken wings in 3 minutes than that will help us find the unit rate by dividing 12 by 3, and then you will get 4. Now that you know the unit rate you will multiply it by 12 and get 48.

Answer:

For this we have to do simple division and multiplication, giving us the answer of 48.

Step-by-step explanation:

The easiest way to solve this is to first divide 12 by 3, giving us 4, the amount of time it would take for Bao to eat a single chicken nugget. And then since the question asks how many Bao can eat in 12 minutes, you would multiply 4 by 12, thus giving you the answer of 48.

Answer:

8:36

Step-by-step explanation:

If he is at his halfway point at 8:24 and it only took him 4 minutes to get one block in than it would take him 12 minutes to get 3 blocks in and if you add 12 more minutes to the time that he's at right now than he would arrive at 8:36.

Answer:

The answer is,2094.75

Step-by-step explanation:

Percentage decrease = 5% × 2,205

2,205 - Percentage decrease =

2,205 - (5% × 2,205) =

2,205 - 5% × 2,205 =

(1 - 5%) × 2,205 =

(100% - 5%) × 2,205 =

95% × 2,205 =

95 ÷ 100 × 2,205 =

95 × 2,205 ÷ 100 =

209,475 ÷ 100 =

2,094.75

Or to be simpler

You find 5% of 2,205 which is 110.25 then subtract it from 2205 which is 2,094.75 and that 5% of 2,205

Answer:

Thus, the probability that exactly 4 don't grow is 0.1361 or 13.61%

Step-by-step explanation:

Binomial Distribution

Consider a random experience that has only two possible outcomes: Success or Failure. Let's call p to the probability that the event has a successful outcome and q to the failure outcome.

It follows that p+q=1, or q=1-p.

Now repeat the random experience n times. We want to calculate the probability of getting x successful outcomes. This can be done with the Binomial Distribution formula:

[tex]\displaystyle P_{x} = {n \choose x}\cdot p^{x}\cdot q^{n-x}[/tex]

Where :

[tex]\displaystyle {n \choose x}[/tex]

Is the number of combinations, calcula ted as follows:

[tex]\displaystyle {n \choose x} =_nC_x=\frac{n !}{x ! (n-x) !}[/tex]

A planted seed has a 70% chance of growing into a healthy plant. The successful outcome has p=0.7 and q=0.3.

The experience is repeated n=8 times. We want to calculate the probability of having 4 failures (not growing seeds) or x=4 successes.

Apply the formula:

[tex]\displaystyle P_{4} = {8 \choose 4}\cdot 0.7^{4}\cdot 0.3^{8-4}[/tex]

[tex]\displaystyle P_{4} = 70\cdot 0.7^{4}\cdot 0.3^{4}[/tex]

[tex]\displaystyle P_{4} = 0.1361[/tex]

Thus, the probability that exactly 4 don't grow is 0.1361 or 13.61%

Answer:

For #5 all you have to do is set down to points in order for it to count. The answer is: (0,2) and (3,6)

Step-by-step explanation:

In order to find where exactly you must plot the points, we plug in what we know. In our equation, the 2 is our y intercept, this means that the point is (0,2) (Side Note: here's another example, (0,6) the 6 would be our y intercept)

From the point (0,2) we use the other value given. The other value given in this case, is our slope. When dealing with slope, we use Rise over Run or Rise/Run. This means that from the 2 on the graph, you rise 3 which would be 5 and you run to the right for 4. This now gets you the points (3,6)

Hope this helps with plotting the other questions! :)

(SIDE NOTE: IF THEY GIVE THE VALUE WITH X AS JUST A NUMBER, YOU CAN PLACE A 1 UNDER IT TO TURN IT INTO A FRACTION. FOR EXAMPLE 3X CAN BE TURNED INTO 3/1 WHICH WOULD THEN BE RISE 3 AND RUN 1.

Answer:

You would have to sell

16 slices to pay for the

original price of the 4

pizzas

Step-by-step explanation:

$7.00 a box so you would have to multiply to get to

full price. $7.00x4=$28.00 The full price is $28.00.

If you are selling the slices for $1.75 each you would

also have to divide to know how many slices to sell

to get back to $28.00. 28.00÷1.75=16. So you would

have to sell 16 slices to get back to the full price.

Hope this helps.

Have a nice day :)
