Answer:

100 and 25 are the perfect squares

Our answers are 100 and 25.

Some insight:

6 = [tex]\sqrt{6}*\sqrt{6}[/tex] -- We cannot simplify the square root of 6 to integers, so no.

100 = [tex]\sqrt{100}* \sqrt{100}[/tex] = 10*10 -- This is a perfect square

25 = [tex]\sqrt{25}* \sqrt{25}[/tex] = 5*5 -- This is a perfect square

5 = [tex]\sqrt{5}* \sqrt{5}[/tex] -- No.

Answer:22. Plug in all the options and see if they are equal

Step-by-step explanation:

Step-by-step explanation:

Numeber 22 is D or -10

Explication

-3|2x + 6| = -12

-6x - 18 = -12

-6x = 6

x = -1

Step-by-step explanation:

In the book immigrant kids, freeman gives readers a glimpse of what it was like to be new and young America. It talked about the journey and what life is like as soon as they arrive.

Pallegrini's experience about rigorous physical examination and the anxiety that followed agrees with freedman's statement about people being afraid of health examinations.

Answer:

Numbers can either be positive or negative. ... Adding and multiplying combinations of positive and negative numbers can cause confusion and so care must be taken. Addition and Subtraction. Two 'pluses' make a plus, two 'minuses' make a plus. A plus and a minus make a minus.

Answer:   True

Step-by-step explanation: Because I got it right on edge

Complete question:

An exam consists of 50 multiple choice questions. Based on how much you studied, for any given question, you think you have a probability of 0.63 of getting the correct answer. Consider the sampling distribution of the sample proportion of correct questions out of 50.

If the population proportion p = 0.63, what is the probability of getting correct answers on less than 60% of the questions?

Answer:

the probability of getting correct answers on less than 60% of the questions is 0.33

Step-by-step explanation:

Given;

number of samples, n = 50

population proportion, P = 0.63

For normal distribution;

np ≤ 60     and n(1-p) ≤ 60

(50 x 0.63) ≤ 60   and   (1-0.63) ≤ 60

31.5 ≤ 60    and 22.2 ≤ 60

The condition is satisfied, then mean of the distribution is given by;

x = p =  0.63

The standard deviation is given by;

[tex]\sigma_p =\sqrt{\frac{P(1-P)}{n} }\\\\ \sigma_p =\sqrt{\frac{0.63*0.37}{50} }\\\\ \sigma_p = 0.068[/tex]

For a  correct answers on less than 60% of the questions

Upper boundary = 0.6

lower boundary = 0

Thus, the probability is given by;

P (p' < 0.6) = 0.33

Therefore, the probability of getting correct answers on less than 60% of the questions is 0.33

Step-by-step explanation:

I defined the following events:

J = travellers check email

K = they use a cell phone to stay connected

M = they have a laptop alongside

P(J) = 0.40

P(K) = 0.30

P(M) = 0.25

P(J n K) = 0.23

P(J U K U M)' = 0.51

P(J|M) = 0.88

P(M|K) = 0.70

A.

We are to find probability of K|J

P(JnK)/p(J)

= 0.23/0.40

= 0.575

B.

P(K|M)

= P(KnM)/P(m)

= 0.21/0.25

= 0.84

C.

P(J U K U M) = 1 - p(J U K U M)'

= 1-0.51

= 0.49

P(JnM) = p(J|M)p(M)

=0.88x0.25

= 0.22

P(JnKnM) = 0.49-0.40-0.30-0.25+0.23+0.22+0.21

= 0.20

P(K|JnM) = P(JnKnM)/p(JnM)

= 0.20/0.22

= 0.909

Answer:

The y-intercept represents the flat fee.

Step-by-step explanation:

The y-intercept on the graph would be the point at which the line cuts across or intercepts the y-axis. At this point, the value of x (miles travelled) would be 0. The y-intercept in this case, would be the flat fee which is given as $2.

At x = 0, f(0) = 2.

The y-intercept represents the flat fee on the graph of f(x).

Answer: Number the students on the school roster. Use a table of random numbers to choose 200 students from this roster for the survey.

Step-by-step explanation:

A truly random sample would be one that gave every member of the population the same chance to be represented. This is why the method that will produce a simple random sample is one where the official school rooster is used and 200 students are selected randomly. This way every student in the school gets an equal chance of representation.

The first option is not random as it excludes students arriving after the first 200.

The second and last options will not be representative nor will it be random because it does not account for students who do not use the gym.

The fourth option limits the number of people that may be picked per class so reduces the chance of simple random selection across the school. This is stratified instead.

Given :

Fran drank 19/20 liter of juice.

1 L = 1.06 qt.

To Find :

How many quarts of juice did she drink.

Solution :

It is given that :

[tex]1 \ L=1.06\ qt\\\\1=\dfrac{1.06\ qt}{L}[/tex]

Now, amount of water he drink :

[tex]\dfrac{19}{20}\times 1 \ L\\\\\dfrac{19}{20}\times 1.06\ \dfrac{qt}{L}\times L\\\\\dfrac{19}{20}\times 1.6 \ qt\\\\1.52\ qt[/tex]

Hence, this is the required solution.

Answer:

[tex]P(x = 0) = 0.061[/tex]

Step-by-step explanation:

Given

[tex]Average = 2.8[/tex]

Required

Determine the probability that no car will arrive.

Since it is a Poisson distribution, the required probability is:

[tex]P(x) = \frac{e^{-m}m^x}{x!}[/tex]

Where

[tex]m = average = 2.8[/tex]

In this case;

[tex]x = 0[/tex]

So:

[tex]P(x) = \frac{e^{-m}m^x}{x!}[/tex]

[tex]P(x = 0) = \frac{e^{-2.8}2.8^0}{0!}[/tex]

[tex]P(x = 0) = \frac{e^{-2.8}*1}{1}[/tex]

[tex]P(x = 0) = e^{-2.8}[/tex]

[tex]P(x = 0) = 0.06081006262[/tex]

[tex]P(x = 0) = 0.061[/tex] --- Approximated
