Answer:

Equation B and Equation C

Step-by-step explanation:

We can pinpoint a solution of an equation on a graph by looking at where the two lines intersect. The points (2,12) quite literally mean when x is 2, y is 12. If two equations intersect at that very point, that is their solution.

Years, Inning and saves are statistically significant ; ERA is not.

Step-by-step explanation:

Earning for staying one additional year :

Multiply slope value of years * 1 = 0.052 * 1 * 100 % = 5.2% (earning increases by 5.2%)

Relives with 10 more saves :

10 * 0.0032 * 100% = 3.2% (earning increases by 3.2%)

Having 100 more innings :

100 * 0.00089 * 100% = 8.9%

If ERA is reduced by 1.5 ; earning will increase by (0.0085*100)% * 1.5 = 1.275%

B.) At 5% level of confidence :

α = 1.64

Years = 0.052/0.026=2

Inning = 0.00089/0.00020 = 4.45

Saves = 0.0032/0.0018 = 1.78

ERA = 0.0085/0.0168 = 0.51

Years, Inning and saves are statistically significant as they are greater than α ; As for ERA, it is not statistically significant (0.51 < 1.64)

A coin is flipped and a random marble is picked from a bag of 10 marbles. Two of the marbles in the bag are red. What is the pro

Lady_Fox [76]

Answer:

$\frac{1}{10}$ is the probability of the coin landing on tail and a red marble being drawn.

Step-by-step explanation:

Given A coin is flipped and a random marble is picked from a bag of 10 marbles. Two of the marbles in the bag are red. we have to find the probability of the coin landing on tail and a red marble being drawn.

P(a red marble)= $\frac{No.\thinspaceof\thinspace red\thinspace marbles}{Total\thinspace marbles}$

= $\frac{2}{10}$

P(getting a tail)= $\frac{1}{2}$

Since both events are independent.

∴ P(he coin landing on tail and a red marble being drawn)

= $P(getting\thinspace a\thinspace tail)\times P(a\thinspace red\thinspace marble\thinspace drawn)$

= $\frac{2}{10}\times \frac{1}{2}$

= $\frac{1}{10}$

Hence, $\frac{1}{10}$ is the probability of the coin landing on tail and a red marble being drawn.

A cone has a radius of 1.2 and a height of 2.9 inches. What is the volume, to the nearest tenth of a cubic inch, of the cone?. E

Mademuasel [1]

Answer:

4.4 cubic inches

Step-by-step explanation:

From the question;

Radius of the cone is 1.2 inches
Height of the cone is 2.9 inches

We are required to determine the volume of a cone;

Volume of a cone is given by the formula;

V=1/3πr²h

Therefore; taking π to be 3.142

Volume =1/3 × 3.142 × 1.2² × 2.9

= 4.373664

= 4.4 cubic inches (to the nearest tenth)

Thus, the volume of a cone is 4.4 cubic inches
