Answer:

6:15 and 8:20 are examples of additional equivalent ratios.

Step-by-step explanation:

The table is:

<u>Books (x) Cost (y)</u>

2 5

4 10

From the table, the ratio Books : Cost is 2:5 or 4:10. Equivalent ratios are obtained, using a graph, from the plot of the line that pass through these two points. In the figure attached, this line is shown. There, it can be seen that ratios 6:15 and 8:20 are equivalent to those from the table.

Answer:

7/5

Step-by-step explanation:

To solve this problem we will use the formula to find the slope of a line given two points (x₁, y₁), (x₂, y₂)

The formula is:

$m= \frac{y{_2} -y_{1}}{x_{2}-x_{1} } \\\\$

So, we're going to use the points (2,5), (-3, -2) in this formula.

$m= \frac{-2-(5)}{-3-(2)} \\m=\frac{-2-5}{-3-2}\\m=\frac{-7}{-5} \\m=\frac{7}{5}$

Therefore, the slope is 7/5

Let X, the number of flaws on the surface of a randomly selected boiler of a certain type, have a Poisson distribution with para

kvasek [131]

Answer:

(a) 0.932

(b) 0.0653

(c) 0.032

(d) 0.316

(e) 0.251

Step-by-step explanation:

From the table with mean parameter μ = 5, we can compute the following cumulative and density probability

(a) $P(X \leq 8) = 0.932$ (cumulative)

(b) P(X = 8) = 0.0653 (density)

(c) $P(9 \leq X) = 1 - P(X \leq 9) = 1 - 0.968 = 0.032$ (cumulative)

(d) $P(5 \leq X \leq 8) = P(X \leq 8) - P(X \leq 5) = 0.932 - 0.616 = 0.316$ (cumulative)

(e) $P(5 < X < 8) = P(X \leq 8) - P(X \leq 5) - P(X = 8) = 0.932 - 0.616 - 0.0653 = 0.251$

What expression is equivalent to 7sqrtx^2/5sqrty^3

V125BC [204]

Answer:

Step-by-step explanation:

Sounds as tho' possible answer choices were listed. Please, share them without being asked to do so. Thank you.

7√(x²) 7√(x²)

------------- = ----------------------

5 √(y³) 5√( y^(3/2) )

We want to get the fractional exponent out of the denominator. To do this, multiply both numerator and denominator by y^(1/2):

7√(x²) 7√(x²) y^(1/2) 7√(x²)·y^(1/2) 7x√y

------------- = --------------------- * ----------- = --------------------- = ----------

5 √(y³) 5√( y^(3/2) ) y^(1/2) 5 √(y²) 5y

This is the final answer. We have succeeded in removing radicals / fractional exponents from the denominator.
