Answer:

Probability of picking an even and then even number = \frac{1}{6}

Step-by-step explanation:

Probability of picking a card with even number,

P(even 1) = \frac{\text{favorable outcomes}}{\text{Total outcomes}} = \frac{\text{even cards}}{\text{Total number of cards}}

               = \frac{2}{4}

               = \frac{1}{2}

Followed by picking a card which is even without putting the first card back.

So an even card is to be picked out of remaining 3 cards.

P(even 2) = \frac{\text{favorable outcomes}}{\text{Total outcomes}}

                = \frac{1}{3}

Now probability of both events = P(even 1) × P(even 2)

= \frac{1}{2}\times \frac{1}{3}

= \frac{1}{6}

Therefore, probability of both the events will be \frac{1}{6}.

KonstantinChe [14]

It will be 2/42 you count out the letters in “ALGEBRA” and then you can the A’s which equal a fraction 2/7 then you subtract 1 from the numerator and the denominator which then equals  1/6. Then you multiply the fractions and get 2/42

A car travels 60km in 30 minutes. In how much time will it cover 100 km?
Daniel [21]

Answer:

About 40 Minutes, Or something close to that

Step-by-step explanation:

The car covers 60 km in 90 minutes or its speed = 60 km*60/90 min = 40 km/hr . So to cover 100 km at the same speed it will take 100/40 = 40 Min

A linear regression is done on data the line of best fit is y= 1.25x-6.25. What is the residual for the point (1,1)?
Damm [24]

Answer:

6

Step-by-step explanation:

Find the predicted y value when x=1:

\hat{y}=1.25x-6.25\\\hat{y}=1.25(1)-6.25\\\hat{y}=1.25-6.25\\\hat{y}=-5

Find the residual:

\text{Residual}=\text{Actual Value}-\text{Predicted Value}\\\text{Residual}=y-\hat{y}\\\text{Residual}=1-(-5)\\\text{Residual}=1+5\\\text{Residual}=6

Because our residual is positive, this is an indicator that our predicted y value is too low.

LOOK AT PICTURE. VOLUME OF CAN PROBLEM
adoni [48]

Answer:

The correct answer is third option.  994

Step-by-step explanation:

<u>Points to remember</u>

Volume of cylinder = πr²h

Where 'r' is the radius and 'h' is the height of cylinder

From the given question we get the cylinder height and radius

The height h = 3 times the diameter of one ball

 = 3 * 7.5 = 22.5 cm

Radius = half of the diameter of a ball

 = 7.5/2 = 3.75 cm

<u>To find the volume of cylinder</u>

Volume of cylinder = πr²h

 = 3.14 * 3.75² * 22.5

 = 993.515 ≈ 994

The correct answer is third option.  994
