Pippa had 35 stickers.
She gave an equal number of stickers to 8 friends.
She gave each friend as many stickers as possible and kept the rest for herself.
How many stickers did Pippa keep for herself?
What is the misconception if a student selects D) 27?

A)3
B)4
C)11
D) 27

Answers

Answer 1

Answer:

A) 3

Pippa kept 3 stickers for herself

Answer to question 2:

The misconception of if a student selects D) 27 is that instead of dividing to find out how many stickers Pippa kept for herself, the student subtracted. They subtracted instead of dividing.

Step-by-step explanation:

It said that Pippa gave each of her friends an EQUAL number of stickers and AS MANY STICKERS AS POSSIBLE. This tells us that to find our answer we need to divide and what ever the remainder is, is how many stickers Pippa kept for herself.

(You will kind of need to do long division for this)

35 ÷ 8 = 4

8 x 4 = 32

35 - 32 = 3

Pippa will give each of her friends 4 stickers and will keep 3 for herself.

Step-by-step explanation for question 2:

35 stickers - 8 friends = 27

D) 27 is the wrong answer to question 1/part 1

Your friend offers to place a bet with you. He will pay you $1 if your favorite sports team wins the game on Tuesday night. But you will pay him $3 if his team wins. Your team has an 80% chance of winning, whereas his only has a 20% chance. This bet is in your favor. True or False.

Answers

False because $1 =$1 not $3

True. The expected value of the bet is positive ($0.2),

What is probability?

Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.

Let's calculate the expected value of the bet for both outcomes:

If your team wins: You get paid $1, so the expected value is 0.8 × $1 = $0.8

If your friend's team wins: You pay $3, so the expected value is 0.2 × -$3 = -$0.6

The overall expected value of the bet is the sum of these two outcomes: $0.8 + (-$0.6) = $0.2

Since the expected value of the bet is positive ($0.2), this means that on average, you can expect to win money if you take this bet. Therefore, the bet is in your favor.

El largo de un terreno es el doble de la medida de su ancho, como se muestra en la imagen. Si el perímetro es de 96 hectómetros, ¿cuáles son las dimensiones del terreno?

Answers

Answer:

Step-by-step explanation:

The following configured particulars are states, in accordance by the interrogate:

Perimeter = 96 hectometers.

Assuming the figure is a square, we can assume that,

S = A side length where,

4s = 96, where all side lengths are equivalent.

If so, then s = 24

Thus, that means that w, denoted as width, must be less than or equal to 24.

In addition, likewise, l, denoted as length, must be less than or equal to 24.

Furthermore, the length is acknowledged or stated to be twice that of the width:

Length = 2w

The listed above may be equated to the following:

2w + 2L = 96

2(24) + 2L = 96

2L + 48 = 96

2L = 48

L = 24

Thus, the width of the figure is equivalent to 24. (Length divided by two).

Thus, the length of the figure is equivalent to 24 (twice the width).

C=0.025x^2 + 3x + 4 x=10

dC= ___________
ΔC= __________

Answers

Answer:

dC=3.5

DC is between 3.475 and 3.525

Step-by-step explanation:

So let dx=1 since the change there is a change in 1 unit.

Find dC/dx by differentiating the expression named C.

dC/dx=0.05x+3

So dC=(0.05x+3) dx

Plug in x=10 and dx=1:

dC=(0.05×10+3)(1)

dC=(0.5+3)

dC=3.5

Let D be the change in cost-the triangle thing.

Since dx=1 we only want the change in unit to be within 1 in difference.

So this means we want it to be from x=9 to x=1] ot from x=10 to x=11.

Let's do from x=9 to x=10 first:

DC=C(10)-C(9)

DC=[0.025×10^2+3×10+4]-[0.025×9^2+3×9+4]

DC=[2.5+30+4]-[0.025×81+27+4]

DC=[36.5]-[2.025+31]

DC=[36.5]-[33.025]

DC=3.475

Now let's do from x=10 to x=11

DC=[0.025×11^2+3×11+4]-[0.025×10^2+3×10+4]

DC=[0.025×121+33+4]-[36.5]

DC=[3.025+37]-[36.5]

DC=[40.025]-[36.5]

DC=3.525

So DC, the change in cost where the change in unit is 1, is between 3.475 and 3.525.

The product of a negative integer and a positive integer is?
PLEASE ANSWER A, B, C

Answers

Answer:

a. negative

b. negative

c. positive

Step-by-step explanation:

a. When a negative and positive integer are being multiplied the product will always be negative. For example, -3*2=-6.

b. Before answering this question it is helpful to realize that it is the exact same as part a. This is because the commutative property states that order does not matter in multiplication. So the answer is also negative, 2*-3=-6.

c. If two negative integers are multiplied then the product will be positive. Whenever two integers of the same sign are multiplied the product is positive. The opposite is true when they have different signs; the product will always be negative. An example of two negative integers would be -3*-2=6.

Step-by-step explanation:

Polynomial long division is virtually identical to numerical long division, except that the quotient term does not require any guessing. It is simply the ratio of the leading terms of the dividend and divisor. As with numerical long division, the product of the quotient term and the divisor is subtracted from the dividend to form the new dividend for the next step.

The process stops when the dividend is of lower degree than the divisor.

In part (a), you need to make sure the dividend expression has all of the powers of x present. This means terms 0x³ and 0x² must be added as placeholders in the given dividend. They will become important as the work progresses.

The wetland area in the town increases by 95% per year.

Answers

Answer:

When t=10, the town is predicted to have around 443 acres of wetlands.

At one time, the town had 740 acres of wetlands.

The wetland area in the town decreases by 5% per year.

Step-by-step explanation:

Given

[tex]f(t) = 740 * (0.95)^t[/tex]

Required

The true statements

[tex](a)\ f(10) = 443[/tex]

We have:

[tex]f(t) = 740 * (0.95)^t[/tex]

Substitute 10 for t

[tex]f(10) = 740 * (0.95)^{10[/tex]

[tex]f(10) = 443[/tex]

Hence, (a) is true

[tex](b)\ f(t) = 740[/tex]

We have:

[tex]f(t) = 740 * (0.95)^t[/tex]

Substitute 740 for f(t)

[tex]740 = 740 * (0.95)^t[/tex]

Divide through by 740

[tex]1 = 0.95^t[/tex]

Express 1 as 0.95^0

[tex]0.95^0 = 0.95^t[/tex]

Cancel out the bases

[tex]0 = t[/tex]

[tex]t = 0[/tex]

Hence, the area had 740 acres initially;

(b) is true

[tex](c)\ r = 5\%[/tex]

We have:

[tex]f(t) = 740 * (0.95)^t[/tex]

Using the general formula

[tex]f(t) = a * b^t[/tex]

By comparison:

[tex]b = 0.95[/tex]

0.95 < 1 means that:

[tex]b = 1 - r[/tex] --- where r = rates

[tex]0.95 = 1 - r[/tex]

Collect like terms

[tex]r = 1 - 0.95[/tex]

[tex]r = 0.05[/tex]

Express as percentage

[tex]r = 5\%[/tex]

Hence, (c) is true

[tex](d)\ f(10) = 492[/tex]

In (a)

[tex]f(10) = 443[/tex]

Hence, (d) is false

[tex](e)\ r = 95\%[/tex]

In (c)

[tex]r = 5\%[/tex] ---- decrement

Hence, (e) is incorrect

Answer: When the town is predicted to have around 443 acres of wetlands.

At one time, the town had 740 acres of wetlands.

The wetland area in the town decreases by 5% per year.

Step-by-step explanation:

The amount of time it takes for a student to complete a statistics quiz is uniformly distributed between 30 and 60 minutes. One student is selected at random. Find the probability of the following events.

a. The student requires more than 55 minutes to complete the quiz.
b. The student completes the quiz in a time between 30 and 40 minutes.
c. The student completes the quiz in exactly 37.23 minutes.

Answers

Answer:

a) 0.1667 = 16.67% probability that the student requires more than 55 minutes to complete the quiz.

b) 0.3333 = 33.33% probability that the student completes the quiz in a time between 30 and 40 minutes.

c) 0% probability that the student completes the quiz in exactly 37.23 minutes.

Step-by-step explanation:

Uniform probability distribution:

An uniform distribution has two bounds, a and b.  

The probability of finding a value of at lower than x is:

[tex]P(X < x) = \frac{x - a}{b - a}[/tex]

The probability of finding a value between c and d is:

[tex]P(c \leq X \leq d) = \frac{d - c}{b - a}[/tex]

The probability of finding a value above x is:

[tex]P(X > x) = \frac{b - x}{b - a}[/tex]

Uniformly distributed between 30 and 60 minutes.

This means that [tex]a = 30, b = 60[/tex]

a. The student requires more than 55 minutes to complete the quiz.

[tex]P(X > 55) = \frac{60 - 55}{60 - 30} = 0.1667[/tex]

0.1667 = 16.67% probability that the student requires more than 55 minutes to complete the quiz.

b. The student completes the quiz in a time between 30 and 40 minutes.

[tex]P(30 \leq X \leq 40) = \frac{40 - 30}{60 - 30} = 0.3333[/tex]

0.3333 = 33.33% probability that the student completes the quiz in a time between 30 and 40 minutes.

c. The student completes the quiz in exactly 37.23 minutes.

Probability of an exact value in a continuous distribution, such as the uniform distribution, is 0%, so:

0% probability that the student completes the quiz in exactly 37.23 minutes.
