K/1.5 = 3
Multiply both sides by 1.5
k(1.5/1.5)=3(1.5)
k(1)=4.5
k=4.5

The legs of a right triangle measure 6 inches and 9 inches. If is the angle between the 6-inch leg and the hypotenuse, sin = ___

mr Goodwill [35]

First find the length of the hypotenuse using pythagorean theorem
<span>c^2 = 5^2 + 7^2
c^2 = 25 + 49
c^2 = 64
c=8 (take the square root in both sides)
Since sin = opposite/hypotenuse,
sin = 5/8 = 0.625</span>

Suppose the linear regression line y = 2.009x - 37.131 predicts a pizza

VARVARA [1.3K]

Answer:

Pizza parlor's profit = $515.344

Step-by-step explanation:

Given that:

Linear regression line for pizza parlor's profit

y = 2.009x - 37.131

x represents the number of pizzas sold

y represent the profit in dollars

Profit for 275 pizzas

Putting x = 275 in given equation

y = 2.009(275) - 37.131

y = 552.475 - 37.131

y = 515.344

Hence,

Pizza parlor's profit = $515.344

Compare the theoretical probability to the experimental probability of landing on H.

cestrela7 [59]

The correct statement comparing the theoretical and experimental probabilities is given as follows:

$\frac{1}{4} < \frac{7}{25}$ .

<h3>What is a probability?</h3>

A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.

The theoretical probability is taken before any experiment. Since the four sections are equal, the theoretical probability is:

T(H) = 1/4.

The experimental probability is taken considering previous experiments. Out of 100 tosses, 28 landed on H, hence:

E(H) = 28/100 = 7/25.

Hence the correct statement is:

$\frac{1}{4} < \frac{7}{25}$ .
