Answer:

C and D

Step-by-step explanation:

So from the equation y = 1.26x + 9.49 we can gather that 9.49 is an initial value because it has to be added to the number with a variable ( 1.26x)

Because 1.26 has a variable of x and x represents a week, we know that the number 1.26 will increases in value depending on how many weeks have passed.

The radius,r , of a sphere is 4 . 3m Calculate the sphere's volume,v . Use the value 3.14 for sqaure, and round your answer to t

kotykmax [81]

Answer:

V(s) = 332,9 m³

Step-by-step explanation:

The volume of a sphere is:

V(s) = (4/3)*π*r³

if we know r = 4,3 m then

V(s) = (4/3)*3,14*(4,3)³

V(s) = 332,8693 m³

Rounding the answer to the nearest tenth

V(s) = 332,9 m³

How do you determine the square root of a term whose variable(s have exponents greater than 2?

4vir4ik [10]

Basic method is Synthetic Division and Factor Theorem

Step-by-step explanation:

For higher-degree equations, the question becomes more complicated than others: cubic and quadratic equations can be solved by similar formulas.

Hence, to avoid those circumstances we can use Synthetic Division and Factor theorem to determine the squares of the given polynomial those who have order higher than 2.

Select the correct answer.

kifflom [539]

Answer:

It is 10√2

Step-by-step explanation:

$= \sqrt{200} \\ = \sqrt{2 \times 100} \\ = ( \sqrt{2} ) \times ( \sqrt{100} ) \\ = \sqrt{2} \times 10 \\ = 10 \sqrt{2}$

What cross section when a cylinder is cut perpendicular to its base

Vika [28.1K]

Answer:

triangle

Step-by-step explanation:

Cross sections perpendicular to the base and through the vertex will be triangles. Below, you can see a plane cutting through the pyramid, part of the pyramid removed, and the cross section. You could also take a slice parallel to the base. Cross sections parallel to the base will be hexagons

mart [117]

Answer: a) 0.545,b) 0.41, c) 0.045, d) not possible.

Step-by-step explanation:

The Sky Ranch is a supplier of aircraft parts. Included in stock are 10 altimeters that are correctly calibrated and two that are not. Three altimeters are randomly selected without replacement. Let the random variable

x represent the number that are not correctly calibrated.

Complete the probability distribution table.

x={0,1,2,3}

P(x=0)=?

P(x=1)=?

P(x=2)=?

P(x=3)=?

Since we have given that

n = 12

number of good one = 3 from 10

number of bad one = 2

So, P(X=0)= $\dfrac{^{10}C_3\times ^2C_0}{^{12}C_3}=\dfrac{120}{220}=0.545$

P(X=1) = $\dfrac{^{10}C_2\times ^2C_1}{^{12}C_3}=\dfrac{90}{220}=0.41$

P(X=2)= $\dfrac{^{10}C_1\times ^2C_2}{^{12}C_3}=\dfrac{10}{220}=0.045$

P(X=3) is not possible.

Hence, a) 0.545,b) 0.41, c) 0.045, d) not possible.
