What is the length of the diagonal for the given rectangular prism to the nearest whole unit? A) 10 cm B) 11 cm 6 cm D) 13 cm







Answers

Hi there! :)

[tex]\large\boxed{\text{B. 11 cm.}}[/tex]

Begin by using Pythagorean theorem to solve for the length of the diagonal of the base:

a² + b² = c²

Use the length and width in the equation:

8² + 3² = c²

64 + 9 = c²

73 = c²

c ≈ 8.54 cm

Now, we can find the length of the diagonal of the prism using our calculated diagonal of the base and the height. Use the same equation:

(8.54)² + 7² = c²

73 + 49 = c²

122 = c²

√122 = c

c = 11.05 ≈ 11 cm. The correct answer is B.

where a and b are the sides, and c is the hypotenuse.

now we will need to solve.

x^2+8^2=14^2
x^2+64=196

x=11.5

Answer: It's 11.5

Explanation ( took so long)

[tex]C = \sqrt{a^{2} + b^{2} }\\14 = \sqrt{8^{2} + b^{2} }\\14 = \sqrt{64 + b^{2} }\\14^{2} = 64 + b^{2} \\196 = 64 + b^{2} \\64 +b^{2} = 196\\b^{2} = 196 - 64\\b^{2} =132\\b = \sqrt{132} \\b = 11.48[/tex]

The results of a recent survey showed that the average cost to rent a car for a week is $276. If the standard deviation is $60,
find the Z-score for a weekly rental of $423.00?
a. 2.45
B. 4.6
C. 7.05
D. -1.88

Answers

B.4.6
I divided 276/60 and got b

The Z-score for a weekly rental is 2.45 which is the correct answer would be option (B).

What is Z -score?

A Z-score is defined as the fractional representation of data point to the mean using standard deviations.

Given the average cost to rent a car for a week is $276

And the standard deviation is $60

To determine the Z-score for a weekly rental of $423.00

Here,

ц = 276

σ = 60

X = 423

⇒ z-score = (X-ц )/σ

Substitute the values,

⇒ z-score =  (423 - 276)/60

⇒ z-score = 147/60

⇒ z-score = 2.45

Hence, the z-score for a weekly rental is 2.45.

The weight, X, of cherry tomatoes selected at random from a very large bin at the local supermarket follows a Normal distribution with mean 3 oz. and standard deviation 2 oz. Suppose we pick 8 cherry tomatoes from the bin at random (independently) and put them in our bag. What is the probability that exactly 5 of the 8 cherry tomatoes weigh less than 4 oz (rounded to the nearest 0.01)?

Answers

Answer: the probability that exactly 5 of the 8 cherry tomatoes weigh less than 4 oz is 0.05

Step-by-step explanation:

Given that;

X has normal distribution has mean µ = 3

standard deviation σ = 2  

now

P( x< 4) = P( (x-µ)/σ /(3-4)/5)

= P( z < -0.5 )

= 0.3085  {from the z-table}

X has binomial distribution with n = 8 and p = 0.3085

so P(x=5)

P(x=5) = 8C₅(0.3085)⁵ (1 - 0.3085)⁸⁻⁵

= 0.0517  ≈ 0.05

Therefore the probability that exactly 5 of the 8 cherry tomatoes weigh less than 4 oz is 0.05

Consider a sample with six observations of 15, 16, 12, 8, 6, and 9. Compute the z-scores for each sample observation.
Sample observation. z-scores
15
16
12
8
6
9

Answers

Answer:

1 ; 1.25 ; 0.25 ; - 0.75 ; - 1.25 ;- 0.5

Step-by-step explanation:

Given the sample observations : 15, 16, 12, 8, 6, 9

Zscore for each sample Observation :

Zscore = (x - mean) / standard deviation

(15 + 16 + 12 + 8 + 6 + 9) / 6 = 11

Mean value (m) = 11

Standard deviation (s) = 5

Sqrt[(x - m)^2 / (n - 1)]

[(15-11)^2 + (16-11)^2 + (12-11)^2 + (8-11)^2 + (6-11)^2 + (9-11)^2] / (6 - 1)

= 80/5 = 16

Sqrt(16) = 4

Zscore = (x - mean) / standard deviation

x = 15

Zscore = (15 - 11) / 4 = 1

x = 16

Zscore = (16 - 11) / 4 = 1.25

x = 12

Zscore = (12 - 11) / 4 = 0.25

x = 8

Zscore = (8 - 11) / 4 = - 0.75

x = 6

Zscore = (6 - 11) / 4 = - 1.25

x = 9

Zscore = (9 - 11) / 4 = - 0.5

mark can cleaN the house in 7 hours. when he cleans the same house with wend, it takes them 3 hours to clean the house. how long would it rake wendy to clean the house by herself

Answers

Answer:5.25

Step-by-step explanation:

3(1/7 + 1/x) = 1

3([x + 7]/7x) = 1

3x + 21 = 7x

4x = 21

x = 21/4 OR 5.25

It will take wendy 5.25hrs to clean the house by herself.

Let x be the time taken by mark to clean the house by herselfLet y be the time taken by wend to clean the house by herselfLet a be the time it took the two to clean the house together.

In order to get the time it take wendy to clean the house by herself, we will use the expression:

1/a = 1/x + 1/y

1/3 = 1/7 + 1/y

1/y = 1/3 - 1/7

1/y = 7-3/21

1/y = 4/21

y =  21/4

y =  5.25hrs

Hence it will take wendy 5.25hrs to clean the house by herself.
