Answer:

48 outfits

Step-by-step explanation:

Using Fundamental Principal of counting

number of outfits that Juan can wear

=number of ties * number of pants * numberof pants

=4*3*4

=48 outfits

The number of different outfits can he wear if he chooses one Tie, one shirt, one pair of pants for each outfit is 48 outfits.

The arrangement of different things or numbers in a number of ways is called a combination.

A permutation is an orderly arrangement of things or numbers. Combinations are a way to choose items or numbers from a collection or group of items without worrying about the items' chronological order.

Given that Juan has four ties, three shirts, and four pairs of pants.

Using the Fundamental Principle of counting,

Number of outfits that Juan can wear

N =number of ties x number of pants x number of pants

N =4 x 3 x 4

N =48 outfits

Therefore, the number of different outfits can he wear if he chooses one Tie, one shirt, one pair of pants for each outfit is 48 outfits.

Answer:

  t = 0.49, 11.91

Step-by-step explanation:

A graphing calculator can show you the answers quickly. The times are 0.49 seconds and 11.91 seconds.

__

We can write the equation as ...

  h = 29

  62t -5t^2 = 29 . . . . . substitute for h

  -5(t^2 -12.4t) = 29

  -5(t^2 -12.4t +6.2^2) = 29 -5(6.2^2) . . . . complete the square

  -5(t -6.2)^2 = -163.2 . . . . . simplify

  t -6.2 = ±√(-163.2/-5) = ±√32.64 . . . . divide by -5, take the square root

  t = 6.2 ±5.71

  t = 0.49, 11.91

The rocket has a height of 29 meters at t=0.49 seconds and t=11.91 seconds.

Answer:

V = 286319.465 cm3

Step-by-step explanation:

First, you have to find the radius to be able to find the volume of a sphere.

The equation for the area of a circle is pi r^2 so you have to so some algebra.

5252 = pi r ^2

5252/pi = r^2

1671.76352 = r^2

sqrt(1671.76352) = r

r = 40.8872048

then you do the equation for the volume of a circle which is 4/3 pi r^3

4/3 pi (40.8872048)^3

4/3 pi 68353.7373

4/3 214739.599

286319.465

Answer:

38.5 cm^2

Step-by-step explanation:

Diameter ( d ) = 7 cm

Radius ( r ) = 7 / 2 cm

Formula : -

Ar ( circle ) = π r^2

π r^2

= ( 22 / 7 ) x ( 7 / 2 )^2

= ( 22 / 7 ) x ( 49 / 4 )

= 38.5 cm^2

Answer:

6 out of 100 and 3 out of 50

Step-by-step explanation:

Answer:

2x

Step-by-step explanation:

x*1 is x

x/1 is also x

x+x=2x

The most likely step would be choice 1: 3x = 16 because in step 3, you should add 3 on both sides. So, 3's would cancel out on the left side and you solve for 13 + 3 = 16. Thus, the answer would be 3x - 16. Hope this helps :)

Equation:  (1 2/3)(2 1/3) = x

Answer:  3 8/9 cups

Step-by-step explanation:

x represents the amount of flour she will need in cups.

To solve, convert the mixed numbers to improper fractions and multiply...

1 2/3 becomes 5/3

2 1/3 becomes 7/3

Now we have

(5/3)(7/3) = x

  35/9 = x

35/9 is 3 8/9 as a mixed number

Answer:

0.989 = 98.9% probability that Mr. Bateman’s class has more students who pass on the first try

Step-by-step explanation:

To solve this question, we need to understand the normal probability distribution, the binomial approximation to the normal and subtraction of normal distributions.

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.

Binomial probability distribution

Probability of exactly x sucesses on n repeated trials, with p probability.

Can be approximated to a normal distribution, using the expected value and the standard deviation.

The expected value of the binomial distribution is:

[tex]E(X) = np[/tex]

The standard deviation of the binomial distribution is:

[tex]\sqrt{V(X)} = \sqrt{np(1-p)}[/tex]

Subtraction of normal distributions:

When two normal variables are subtracted, the mean is the subtraction of the means while the standard deviation is the square root of the sum of the variances.

Among Mr. Adams’s students, 68% pass the driving test on the first try. Sample of 40.

This means that [tex]p = 0.68, n = 40[/tex].

[tex]\mu_A = np = 40*0.64 = 27.2[/tex]

[tex]s_A = \sqrt{40*0.68*0.32} = 2.95[/tex]

74% of Mr. Bateman’s students pass the driving test on the first try. Sample of 50:

[tex]p = 0.74, n = 50[/tex]

[tex]\mu_B = np = 50*0.74 = 37[/tex]

[tex]s_B = \sqrt{50*0.74*0.26} = 3.1016[/tex]

What is the probability that Mr. Bateman’s class has more students who pass on the first try?

This is the probability that B - A is greater than 0.

Distribution B - A:

Mean:

[tex]\mu = \mu_B - \mu_A = 37 - 27.2 = 9.8[/tex]

Standard deviation:

[tex]\sigma = \sqrt{s_A^2 + s_B^2} = \sqrt{2.95^2 + 3.1016^2} = 4.28[/tex]

Probability of being larger than 0:

1 subtracted by the pvalue of Z when X = 0. So

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

[tex]Z = \frac{0 - 9.8}{4.28}[/tex]

[tex]Z = -2.29[/tex]

[tex]Z = -2.29[/tex] has a pvalue of 0.011

1 - 0.011 = 0.989

0.989 = 98.9% probability that Mr. Bateman’s class has more students who pass on the first try
