Answer:

0.4 = 40% of this group likes chocolate

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

In which

P(B|A) is the probability of event B happening, given that A happened.

[tex]P(A \cap B)[/tex] is the probability of both A and B happening.

P(A) is the probability of A happening.

In this questions:

Event A: Likes sprinkles

Event B: Likes chocolate.

20% of your friends like sprinkles (S) topping.

This means that [tex]P(A) = 0.2[/tex]

8% of your friends like Chocolate (C) and also like sprinkles (S).

This means that [tex]P(A \cap B) = 0.08[/tex]

Of the friends who like sprinkles, what proportion of this group likes chocolate?

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.08}{0.2} = 0.4[/tex]

0.4 = 40% of this group likes chocolate

Answer:

Step-by-step explanation:

-6.34

You can just use the calculator. :)

Answer:

-6.34

Step-by-step explanation:

so the -6 would stay the same since it is a whole number. since the denominator is half of 100, you would multiply it by 2 (17/50*2) to keep the fraction equal you would do the same to the numerator (17*2/100) getting 34/100. you would put a decimal before the 34 since it is not whole, getting -6.34

Answer:

170

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].

The margin of error is of:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

Assume:

[tex]\pi = 0.06[/tex]

90% confidence level

So [tex]\alpha = 0.1[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.1}{2} = 0.95[/tex], so [tex]Z = 1.645[/tex].

What is the smallest sample size required to obtain the desired margin of error?

This is n for which M = 0.03. So

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

[tex]0.03 = 1.645\sqrt{\frac{0.06*0.94}{n}}[/tex]

[tex]0.03\sqrt{n} = 1.645\sqrt{0.06*0.94}[/tex]

[tex]\sqrt{n} = \frac{1.645\sqrt{0.06*0.94}}{0.03}[/tex]

[tex](\sqrt{n})^2 = (\frac{1.645\sqrt{0.06*0.94}}{0.03})^2[/tex]

[tex]n = 169.6[/tex]

Rounding up, 170.

Answer:

Debit

Step-by-step explanation:

Assets and expenses have natural debit balances. This means positive values for assets and expenses are debited and negative balances are credited. For example, upon the receipt of $1,000 cash, a journal entry would include a debit of $1,000 to the cash account in the balance sheet, because cash is increasing.

Answer:

Your answer is 65

Answer:

Solution given:

<3+90=180°[co interior angle]

<3=180-90

<3=90° is a required answer.

Answer:

6 is 140°

step by step

same line meant that the angle abc equals 180°

so DBC =180-40=140° .

Answer:

im assuming that we are solving for g. i got 8x^2-10x-3 over x

Step-by-step explanation:

1. gx^2=8x2−10x−3

then u divide both sides by x which gets u gx over x = 8x^2-10x-3 over x

i hope that makes sense and helps!

Answer:

n = 6

Step-by-step explanation:

Given the following data;

Sum of interior angles, S = 720°

Mathematically, the sum of the interior angles in a regular polygon is given by the formula;

S = 180(n - 2)

Where;

n is the number of sides.

S is the sim of the interior angles

720 = 180(n - 2)

720 = 180n - 360

180n = 720 + 360

180n = 1080

n = 6

Answer:12

Step-by-step explanation:

Answer:

the answer is C

Step-by-step explanation:

the percent decrease is by 8 percent

Answer:

12 feet

Step-by-step explanation:

w = width

w+2 = length

w(w+2) = 8

w² + 2w - 8 = 0

(w+4)(w-2) = 0

w = -4   exclude because a length cannot be negative

w = 2

length = 2+2 or 4

P = 2(2)+2(4)

P = 4+8 or 12

Answer:X=(-2,3) or X= (0,0)

Answer:

a) [tex]Z = -2.88[/tex]

b) [tex]Z = -0.96[/tex]

c) 40 weeks gestation babies

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

a. Find the standardized score (z-score), relative to all U.S. births, for a baby with a birth length of 45 cm.

Here, we use [tex]\mu = 52.2, \sigma = 2.5[/tex]. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{45 - 52.2}{2.5}[/tex]

[tex]Z = -2.88[/tex]

b. Find the standardized score of a birth length of 45 cm. for babies born one month early, using 47.4 as the mean.

Here, we use [tex]\mu = 47.4, \sigma = 2.5[/tex]. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{45 - 47.4}{2.5}[/tex]

[tex]Z = -0.96[/tex]

c. For which group is a birth length of 45 cm more common?

For each group, the probability is 1 subtracted by the pvalue of Z.

Z = -2.88 has a lower pvalue than Z = -0.96, so for Z = -2.88 the probability 1 - pvalue of Z will be greater. This means that for 40 weeks gestation babies a birth length of 45 cm is more common.

Answer:

Option D is the correct answer

Hello there!!

The answer would be D. The symbol you see, [tex]\geq[/tex], means 'greater than or equal to'. This correctly fits the wording - Margo must sell AT LEAST 38 tubs. So the lowest number she can sell is 38. And that means the answer is D.

I hope this helps!

Debit Office Supplies Expense: 15,066, Credit Office Supplies: 15,066

Step-by-step explanation:

Office Supplies Account started with a $4000 debit balance.

Apply the adjustment of the end of the year total. $4000-$2334 = $1666.

The company purchased supplies for $13,400

$13,400 + $1666 = $15,066

Answer: The correct choice is letter C.

Step-by-step explanation:

Cosine = adjacent/hypotenuse

In this triangle, you are looking for angle degree of cos X.

When finding an angle degree, you must use the inverse of whatever trig ratio you are using. In this case, you would use [tex]cos^{-1}[/tex].

The adjacent side from x is 12 and the hypotenuse is 15.

So you form your trig ratio which is your answer.

[tex]cos^{-1}[/tex] [tex]\frac{12}{15}[/tex] = 0.80

Answer:

(-4,-6),(-2,-5),(0,-4),(4,-2)

Step-by-step explanation:

(x,y)

x represents the x co-ordinate of a point

y represents the y co-ordinate of a point

Answer:

-6,-2,0,4

Step-by-step explanation:

Since x comes before y in an ordered pair, you would need to find the where the x is, then search for the y number it connects with. For finding the x, use the y part, and look for the numbe it connects with on the graph. In this case youy pairs would be, (-4,-6) (-2,-5) (0,-4) (4,-2). Hope I helped!
