Answer:

7/8 of an hour

Step-by-step explanation:

We multiply the total of the movie, 3 1/2 hours, by the fraction she watched, 1/4:

1/4(3 1/2)

To multiply these, we convert the mixed number to an improper fraction.  We multiply the whole number, 3, by the denominator, 2; this gives us 6.  We add the numerator, 1; this gives us 7.  This makes it 7/2:

1/4(7/2)

To multiply fractions, we multiply straight across:

(1*7)/(4*2) = 7/8

How many solutions does this
weeeeeb [17]
<h3>Answer:</h3>

D)

<h3>Step-by-step explanation:</h3>

Given equation:

  • 3s = 8s - 5s

To simplify this equation, we need to isolate the variables on one side of the equation and the constants on the other side of the equation. To do this, we can <u>simplify the R.H.S</u> as like terms can subtract.

⇒ 3s = 8s - 5s

⇒ 3s = s(8 - 5)

⇒ 3s = s(3) = 3s

⇒ 3s= 3s

Since both sides of the equation are the same, this system of equations has infinite solutions.

<h3 /><h3>Check:</h3>

We can check our answer by substituting the value of "s" into the equation. As a result, you will see that many values of "s" are satisfying the equation. Thus, Option D is correct.

Urgent!! Math help!!
Sindrei [870]

Answer/Step-by-step explanation:

Problem 1:

Reference angle = 36°

Opposite = x

Adjacent = 7

Thus, apply trigonometric ratio as follows:

tan 36 = x/7

Multiply both sides by 7

7 × tan 36 = x

x = 5.09 (nearest hundredth)

Problem 2:

Reference angle = 63°

Opposite = 12

Hypotenuse = x

Thus, apply trigonometric ratio as follows:

Sin 63 = 12/x

Make x the subject of the formula

x = 12/sin 63

x = 13.47 (nearest hundredth)

g Which one of the following best describes an advantage of using a Poisson distribution (Model 1) over the distribution in Mode
laila [671]

Answer:

It reduces the amount of unknowns needed for modeling.

Step-by-step explanation:

Let's first look at the characteristics of poisson distribution.

The Poisson distribution has the following characteristics:

1. It is a discrete distribution.

2. The occurrences in each interval can range from zero to infinity.

3. Each occurrence is very independent of the other occurrences.

4. It helps describes discrete occurrences over an interval.

5. It reduces the amount of constant and unknown needed for modeling an equation.
