Answer:

Step-by-step explanation:

From the given question.

We can write the null hypothesis & the alternative hypothesis as:

Null hypothesis:

\mathbf{H_o: \mu \leq 6}

Alternative hypothesis:

\mathbf{H_{a}:\mu >6}

From above, let's think about the type I error we could make and the type II error we could make.

<u>Type I error:</u>

The type I error at the null hypothesis showcases that the snow level is at 6 inches or below 6 inches, but we falsely concluded that the snow level is high above sea level.

<u>Type II error:</u>

Here, the snow level is literally above 6 inches, hence, we failed to conclude that the snow level is above 6 inches.

Thus, the consequences of the above analysis showcase that type II error has higher severe consequences because it may result in a situation that may endanger the passengers' safety.

Yolanda's Coffee Shop makes a blend that is a mixture of two types of coffee. Type A coffee costs Yolanda $5.20 per pound, and t
MAXImum [283]

Answer:

78 pounds

Step-by-step explanation:

Let's say Yolanda makes a pounds of Type A coffee and b pounds of Type B coffee. Since the total number of pounds is 130, we can write the equation:

a + b = 130

We know the cost of Type A coffee is $5.20/lb and the cost of Type B coffee is $4.05/lb, so since the total cost is $586.30, we can write:

5.20a + 4.05b = 586.30

We can now solve the system of equations:

a + b = 130

5.20a + 4.05b = 586.30

Manipulate the first equation by subtracting b from both sides:

a + b = 130

a = 130 - b

Substitute 130 - b for a in the second equation:

5.20a + 4.05b = 586.30

5.20 * (130 - b) + 4.05b = 586.30

676 - 5.20b + 4.05b = 586.30

Move the terms with b to one side:

1.15b = 89.70

b = 78

Thus, Yolanda used 78 pounds of Type B coffee.

Y=3/2x-1<br> -6x+4y=-4<br> Does this have no solution or infinitely many solutions please explain.
Aleks04 [339]

Answer:

infinitely many solutions

Step-by-step explanation:

Let's eliminate the fractional coefficient in the first equation by multiplying that equation by 4:

4y = 6x - 4

The second equation can be rewritten as 4y = 6x - 4, so the two equations are actually identical.  They have infinitely many solutions.
