Use the grid to draw a rectangle with an area of 1,125 square units ad a side of 25 units
guajiro [1.7K]

Answer:

For grid, Please see attachment area of rectangle.

Explanation:

We are given the area of rectangle is 1,125 square unit whose one side is 25 units.

As we know the formula of area of rectangle =Length \times Width

Let 25 units is width of rectangle

Area = 1,125

\therefore Length=\frac{1125}{25}=45 units

Dimension of rectangle 45 x 25.

Now we draw the grid graph of rectangle.

First we take a grid paper with 1 square unit area of each box. Now we draw line with 45 unit horizontal(Length) and 25 unit vertical (Width).

We make a closed figure with four line opposite side equal and parallel.

Inside box, total number of box must be 1,125 because area of 1 small box 1 square unit.

Total area of all box = 1,125 x 1  = 1,125 square units.

A tour bus starts from Memphis and heads to Miami at 50 mph. Three hours later a truck pursues the bus at a speed of 65 mph. How
Nina [5.8K]
Three hours after the bus starts out, it's 150 miles ahead of the truck. Then the truck starts out, and it gains (65-50)=15 miles on the bus every hour. If neither of them ever stops for anything, the truck will catch up to the bus in ( 150/15 ) = 10 hours. . . . (The hint is useless.)

The null and alternative hypotheses are given. Determine whether the hypothesis test is left-tailed, right-tailed, or two-tailed
OlgaM077 [116]

Answer:

Test is Left tailed test

Parameter tested is standard deviation

Step-by-step explanation:

We are given the hypothesis as;

Null hypothesis; H0: σ = 8.6

Alternative hypothesis; H1: σ < 8.6

Where;σ is a constant generally known in statistics as the standard deviation.

Now, it's the alternative hypothesis that will let us know whether this is left tailed, right tailed or two tailed.

Alternative hypothesis says σ < 8.6.

This means that the values of σ that satisfy this hypothesis are less than 8.6 and thus are on the left hand side of 8.6 on a number line. Thus, the shaded region in a normal distribution curve will be on the left.

Thus, it's a left tailed test
