Answer:

(c)

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos42°  = \frac{adjacent}{hypotenuse} = \frac{x}{12}

Multiply both sides by 12

12 × cos42° = x, hence

x ≈ 8.9 → (c)

A company manufacturers video games with a current defect rate of 0.95%. To make sure as few defective video games are delivered
RSB [31]
There would be about 19 defective products delivered.

First, let's start with the number of defective games. 
100000 x 0.0095 = 950

Now, the test will catch 98% of those defects. That means 2% of the defects will get through to the consumers.
0.02 x 950 = 19

EleoNora [17]

Answer:

Step-by-step explanation:

Given that a professor sets a standard examination at the end of each semester for all sections of a course. The variance of the scores on this test is typically very close to 300.

H_0: s^2 = 300\\H_a: s^2 \neq 300

(Two tailed test for variance )

Sample variance =480

We can use chi square test for testing of hypothesis

Test statistic = \frac{(n-1)s^2}{\sigma^2} \\=62.4

p value = 0.0100

Since p <0.05 our significance level, we reject H0.

The sample variance cannot be claimed as equal to 300.

Why is the quotient of three divided by one-fifth different from the quotient of one-fifth divided by three? Tell a story that c
miskamm [114]

Answer:

These quotients are different because of what division means.

Step-by-step explanation:

When you divide you start with a total and break it into equal groups. If you started with three and broke them into groups of 1/5, that is different then starting with 1/5 and breaking into three groups.

If you had 3 cups of Chex mix and made servings of 1/5 of a cup. How many servings could you get? This is 3 divided by 1/5.

What is the slope-intercept form of the function described by this table?
Andru [333]

Answer:

<em>y = - 3x + 4 </em>

Step-by-step explanation:

m = \frac{y_{2} -y_{1} }{x_{2} -x_{1} }

y - y_{1} = m( x - x_{1} ) Point-slope form

y = mx + b  Point-intercept form

(1, 1)

(2, - 2)

m = (- 2 - 1 ) / (2 - 1) = - 3

y - 1 = - 3( x - 1 )

<em>y = - 3x + 4</em>
