Hey! This is due at like 11 pm!

rewona [7]

Answer:

$7$

Step-by-step explanation:

Use the Pythagorean Theorem

$a^2 + b^2 = c^2$

$a$ and $b$ are either opposite or adjacent

$c$ is the hypotenuse.

1. Look for the right angle. (the little box). The right angle "points" to the hypotenuse. In this case, the hypotenuse is 25.

2. Because we know the hypotenuse is 25. We know that 24 is our adjacent. Meaning our missing side is the opposite.

3. Plug in the numbers. $24^2 + b^2 = 25^2$

4. Solve:

$24^2 + b^2 = 25^2$

$576 +b^2=625$

$b^2 = 625-576$

$b^2 = 49$

$\sqrt{b^2} = \sqrt{49}$

$b = 7$

Hope this helps! Lmk if you have questions.

: Mark wants to fence 4 rectangular gardens, each with a length of feet 9/1/4 and a width of feet 4/1/2 . What is the total leng

Anastaziya [24]

Answer:

Mark needs 110 ft. fencing to surround all 4 gardens.

Step-by-step explanation:

Mark wants to fence 4 rectangular gardens. So we calculate the perimeter of the each garden by this formula

P = 2(L) + 2(W)

Total Length of the garden = $9\frac{1}{4} + 9\frac{1}{4}$

= $\frac{37}{4}+ \frac{37}{4}$

Length = 18.5 feet

Total width of the garden = $4\frac{1}{2} + 4\frac{1}{2}$

= $\frac{9}{2}+ \frac{9}{2}$

Width = 9.0 feet

Perimeter of the garden = 18.5 + 9 = 27.5 feet

Mark wants to fence 4 garden

Therefore, 27.5 × 4 = 110 feet.

Mark needs 110 ft. fencing to surround all 4 gardens.

It is believed that 11% of all Americans are left-handed. A college needs to know how many left-handed desks to place in the big

Vinil7 [7]

Step-by-step explanation:

The random variable (x) here would be a randomly selected student from the college that is left-handed.

The population parameter would be 11% of America's total population. The total population as of 2019 is believed to be 328.2 million, and 11% of that figure is about 36.1 million (thirty-six million one hundred thousand).
Hypotheses: Remember, the null hypothesis usually reflects the held view of the researcher, and since we are told the college wants to know if the data provide enough evidence to show that students at this college have a different percentage of left-handers than the general American population. It could read; There is a statistically significant difference in the percentage of left-handers in the college than the American population. While the alternate hypothesis could read; There is no statistically significant difference in the percentage of left-handers in the college than the American population.

The Type I error implies rejecting the null hypothesis when it is actually true. That is: Rejecting that the % of all students from that college that are left-handed is 11 % when the % is really 11 %.

The Type II error implies accepting the null hypothesis when it is actually false. That is: Failing to reject that the % of all students from that college that are left-handed is 11 % when the % is actually different.

GaryK [48]

Given that the die-cast plane is scaled at 1 inch to 1 foot. This means that for each foot of the actual plane, the toy is 1 inch.

Therefore, the dimensions of the actual plane is given by 1 x 6.5 inches wide by 1 x 8.5 inches long = 6.5 inches wide by 8.5 inches long.
