You roll a 10 sided die. What is the probability of rolling a odd number and less than 4?
zzz [600]

Answer:

Probability of it being odd would be one half, and for less than four would be 2/10

Step-by-step explanation: Since it can only be odd the chance for it landing on odd is half.

then since it has to be lower than 4, and since there's only 1, and 3  that are odd and lower than four you would only have a 20 perecent chance of it landing on 1 or 3

Together, teammates Pedro and Ricky got 2679 base hits last season. Pedro had 283 more hits than Ricky. How many hits did each p
Sergio [31]

Answer:

Pedro: 1481 Base hits

Ricky: 1198 Base hits

Step-by-step explanation:

First, take the total amount of base hits last season 2679, then subtract how many more Pedro has 283.

2679 - 283 = 2396 now divide the sum in half  2396 ÷ 2 = 1198 that gives you how many each player has, you're then going to add the amount that you took off to only Pedras total since he had 283 more

Pedro: 1198 + 283 = 1481

Ricky: 1198

Write the equation for the following relation. R = {(x, y): (4, 5), (8, 7), (12, 9), (16, 11), . . .} and show work
timama [110]

Let

A(4,5) B(8,7) C(12,9) D(16,11)

1) Find the slope AB

m=(y2-y1)/(x2-x1)

m=(7-5)/(8-4)=0.5

2) Find the slope BC

m=(9-7)/(12-8)=0.5

3) Find the slope CD

m=(11-9)/(16-12)=0.5

The points represent a linear function

so

<u>Find the equation of the line with m=0.5 and the point A(4,5)</u>

we know that

y-y1=m*(x-x1)

y-5=0.5*(x-4)

y=0.5*x-2+5

y=0.5*x+3

therefore

<u>the answer is</u>

The equation is equal to y=0.5*x+3
