16. If y varies directly as x, and x = 9 when y = 15, find y when x = 33?​

Answer:

The y-intercept is -3.2

Answer:

See Below

Step-by-step explanation:

I'm not going to do the homework for you, but I will complete three of the problems to help you understand the process.

We are converting between different units of measurement.

Here are the conversions to know:

12 inches = 1 foot

3 feet = 1 yard

1760 yard = 1 mile

5280 feet = 1 mile

#1

We need to convert 7 feet into inches.

7 feet * 12 inches per foot = 84 inches

Now we know:

84 inches = 7 feet

What's the difference is between 84 inches, and 18 inches?

84 inches - 18 inches = 66 inches

We need 66 more inches to get a length of 7 feet.

#2

We need to convert 2 miles into yards.

2 miles * 1760 yards per mile = 3520 yards.

Now we know:

3520 yards = 2 miles

What's the difference between 3520 yards and 2000 yards?

3520 yards - 2000 yards = 1520 yards

We need 1520 more yards to make 2 miles

#3

We need to convert 108 inches into feet.

108 inches / 12 inches per foot = 9 feet

Since there is no remainder,

9 feet = 108 inches.

Hopefully you can see what is going on here and do the rest yourself.

Answer:

y = -1.6x + 4

Step-by-step explanation:

y = mx + b

y = (-1.6)x + (4)

y = -1.6x + 4

The equation of line with a slope of -1.6 and a y-intercept of 4 in slope- intercept form is,

⇒ y = - 1.6x + 4

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

We have to given that;

Slope of the line (m) = - 1.6

And, The y - intercept = 4

We know that;

The slope intercept form of an equation of line is,

⇒ y = mx + b

Where, 'm' is slope of the line and 'b' is y - intercept of the line.

Hence, The equation of line with a slope of -1.6 and a y-intercept of 4 in slope- intercept form is,

⇒ y = mx + b

⇒ y = - 1.6x + 4

The transformation is

g(x) is the function f(x) which is shifted 3 units left and 1 unit up

If you are given

g(x)=log2(x+3)+1 and f(x)=log2x

Then the transmission is g(x) = f(x + 3) + 1, which indicates that g(x) is the function f(x) which is shifted 3 units left and 1 unit up

Answer:

She/He is right it's C. Tysm!

The correct answer is:

A) −12d−15 (None of the options provided are equivalent to the given expression.)

To simplify the expression −4(3d−2)−7, we can apply the distributive property by multiplying -4 to each term inside the parentheses:

−4(3d−2)−7 = -4 * 3d + (-4) * (-2) - 7

This gives us:

-12d + 8 - 7

Combining like terms:

-12d + 1

So the expression is equivalent to -12d + 1.

Therefore, the correct answer is:

A) −12d−15 (None of the options provided are equivalent to the given expression.)

Answer:

A) Option B: Paired t-test

B) The company finds "SUFFICIENT" evidence of an increase in sales, when in reality there is "A DECREASE" in sales

Step-by-step explanation:

A) Let's look at the options.

a) One sample t-test: This t-test is a statistical hypothesis test that's used to find out whether an unknown population mean has a different value from the sample mean.

b) Paired t-test: This is used to compare mean at different times from the same group.

c) Chi-squared test of independence: This test is one that is used to determine whether the associated variables are related or independent.

d) One proportion z-test: This test is used to compare an observed proportion to that of a theoretical proportion.

e) Two sample t-test: This is used to test if the unknown population mean that is gotten from two groups are equal or not.

Now, from the question, we see that A random sample of 30 branches is chosen, and the daily sales for these branches are recorded.

Later on, All the employees at these branches then undergo a customer skills training program, and shortly thereafter the daily sales at these 30 branches are again recorded.

This means that we are trying to compare the mean within the same group but at different times. This corresponds to the definition of Paired t-test.

B) A Type II error occurs when we accept a null hypothesis that is actually false.

The type II error in this case is that:

The company finds "SUFFICIENT" evidence of an increase in sales, when in reality there is "A DECREASE" in sales
