Answer:

The answer to your question is:

7.- y = 6 units

8.- a = 10.6 in

9.- 41.6 ft

Step-by-step explanation:

7.- That is a right triangle and the hypotenuse is y.

Use the pythagorean theorem to find y.

y² = (3√2)² + (3√2)²

y² = 9(2) + 9(2)

y² = 18 +18

y² = 36

y = 6 units

8.-

hypotenuse = 15 in

c² = a² + b²

a = b so

c² = a² + a²

c² = 2a²

c² / 2 = a²

a² = 15² / 2

a² = 112.5

a = 10.6 in

9.-

Use trygonometry to solve this triangle

height = 36 feet

sin Ф = 36 / hypotenuse

hypotenuse = 36 / sin Ф

hypotenuse = 36 / sin60

hypotenuse = 36 / 0.86

hypotenuse = 41.6 ft

Here is a simple probability model for multiple-choice tests. Suppose that each student has probability p of correctly answering

Alla [95]

Answer:

a) The probability that Jodi scores 78% or lower on a 100-question test is 4%.

b) The probability that Jodi scores 78% or lower on a 250-question test is 0.023%.

Step-by-step explanation:

a) To approximate this distribution we have to calculate the mean and the standard distribution.

The mean is the proportion p=0.85.

The standard deviation can be calculates as:

$\sigma=\sqrt{\frac{p(1-p)}{n} }= \sqrt{\frac{0.85*(1-0.85)}{100} }=0.04$

To calculate the probability that Jodi scores 78% or less on a 100-question test, we first calculate the z-value:

$z=\frac{p-p_0}{\sigma} =\frac{0.78-0.85}{0.04} =-1.75$

The probability for this value of z is

$P(x$

The probability that Jodi scores 78% or lower on a 100-question test is 4%.

b) In this case, the number of questions is 250, so the standard deviation needs to be calculated again:

$\sigma=\sqrt{\frac{p(1-p)}{n} }= \sqrt{\frac{0.85*(1-0.85)}{250} }=0.02$

To calculate the probability that Jodi scores 78% or less on a 250-question test, we first calculate the z-value:

$z=\frac{p-p_0}{\sigma} =\frac{0.78-0.85}{0.02} =-3.5$

The probability for this value of z is

$P(x$

The probability that Jodi scores 78% or lower on a 250-question test is 0.023%.

A baseball player has a batting average of 0.26. What is the probability that he has exactly 6 hits in his next 7 at bats

LenKa [72]

Answer:

0.0016

Step-by-step explanation:

Batting average, p = 0.26

n = 7

x = 6

With p = 0.26 as success rate

1-p is equal to failure rate which is = 0.74

We have to solve this by using the binomial distribution formula.

P(X= x)

= nCx * p^x * (1-p)^(n-x)

P(X = 6)

=7C6 × 0.26^6 ×(1-0.26)^(7-6)

= 7 × 0.0003089 × 0..74¹

= 0.0016

So probability that he has exactly 6 hits in his next 7 bats is equal to 0.0016.

Jenny wants to rent a truck for one day. She contacted two companies. Laguana's Truck Rentals charges $20 plus $2 per mile. Salv

Anna71 [15]

Answer:

20 miles.

Step-by-step explanation:

Let m be number of miles.

Laguana's Truck Rentals charges $20 plus $2 per mile.

Total cost of Laguana's Truck = $20+2m$ .... (1)

Salvatori's truck rentals charges $3 per mile.

Total cost of Salvatori's truck = $3m$ ... (2)

We need to find the number of hours after that the total cost for both companies will be the same.

$3m=20+2m$

$3m-2m=20$

$m=20$

Therefore, after 20 miles the total cost for both companies will be the same.
