Answer:

11.25 or 11 1/4

Step-by-step explanation:

seeing as how tiled in this sense essentially means 'cut' we have to look at the following rectangle as 2 separate rectangles instead of one whole

so we'll let the biggest rectangle be rectangle one and the smallest rectangle two-

now we need the dimensions of each one-

rectangle one

l=5 w=2

rectangle two

l=5 w=1/4

now let us set up the equation and solve-

a=lw

rectangle one

a=5*2=10

rectangle two

a=5*1/4=1.25

and the last step is to add together the areas of both rectangles

10+1.25=11.25

and since you need your answer as a mixed number the answer is 11 1/4

(to do this you just put 11.25 over 100 and then simplify)

good luck :)

i hope this helps

brainliest would be highly appreciated

have a nice day!

Answer:

$66.03 in total.

Step-by-step explanation:

$66.03 because 6.5% is 0.065 and $62.00 times 0.065 equals $4.03. $62.00 plus $4.03 is $66.03.

Step-by-step explanation:

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

Step-by-step explanation:

Answer:

[tex]radius \: \: r = 5 \: cm \\ area = \pi {r}^{2} \\ = 3.14 \times (5) {}^{2} \\ = 78.5 \: {cm}^{2} [/tex]

Answer:

[tex]78.5cm^{2}[/tex]

Step-by-step explanation:

[tex]A=\pi r^{2}[/tex]

[tex]A=(\pi )(5)^{2}[/tex]

[tex]A=78.5[/tex]

so I guess rounding it to 79

Answer:

D + 550 = X

The band accounted for 25% of the budget.

Step-by-step explanation:

Since Fairfield High spent D dollars for refreshments, decorations, and advertising for a dance, and in addition, they hired a band for $ 550, to write an expression that represents the cost of the band as a fraction of the total amount spent for the school dance and determine, if D is $ 1650, what percent of the budget did the band account for, the following calculations must be performed:

D + 550 = X

D = 1650

1650 + 550 = X

2200 = X

2200 = 100

550 = X

550 x 100/2200 = X

55,000 / 2,200 = X

25 = X

Therefore, the band accounted for 25% of the budget.

Answer:

14%

Step-by-step explanation:

Answer:

14%

Step-by-step explanation:

It is like subtraction, if you do 14 - 100 you get 86 so you took away 14 from 100 so you would get 14%

- Each friend has 10 nails to paint

- There are 8 friends

- Jackie finished painting 4 friend's nails

If there are 8 friends, and each friend has 10 nails to paint, then there are 80 nails that need to be painted in total.

Jackie finished painting 40 nails.

So the math sentence will be:

80 - 40 = 40

--------------------------------------------------

Jackie needs to paint 40 more nails.

Answer:

4 hrs

Step-by-step explanation:

22.8-17.6=5.2

so they are 5.2 miles apart.

Let they meet after t hrs.

distance coverd by Quico in t hrs=2.6t

distance covere by Chespirito in t hrs =3.9t

3.9t-2.6 t=5.2

or 1.3 t=5.2

t=5.2/1.3 =4
