Answer:
.5
Step-by-step explanation:
1 half of any thing is 50 percent and 50 percent is written as a decimal when you move the decimal point twice to the left giving you .5
Sample space ={13 H + 13 D + 13 S + 13 C} = 52 cards
P(getting one heart) = 13/52 = 1/4
P( getting NO heart) = 1-1/4 = 3/4 = 0.75
I think it's 138 Long by 109.5 more accurate .
92/73 = 1.26
120/100 = 1.2
138/109.5 =1.26
Hence 138 by 109.5 is more proportionate
Answer:
30 gallons of 6% milk, and 45 gallons of 1% milk.
x=quarts of 6% butterfat
First, write an equation.
0.06x+0.01(75-x)=0.03*75
Multiply both sides by 100.
0.06x*100+0.01*100(75-x)=100*0.03*75
Simplify
6x+75-x=3*75
6x+75-x=225
Solve
5x=225-75=150
5x=150
x=30
75-30=45
So, we need 30 gallons of 6% milk, and 45 gallons of 1% milk.
Step-by-step explanation:
Answer:
Mean=9.75
Median = 9.5
Mode = 8,9,10,12
Range = 6
Step-by-step explanation:
Arrange number in ascending order;
6,7,8,8,9,9,10,10,11,12,12,15
Mean = sum of terms/number of terms
=(6+7+8+8+9+9+10+10+11+12+12+15)/12
=117/12
=9.75
Median = middle number in a list; since we have two numbers we add them together and divide by 2
= (9+10)/2
= 19/2
=9.5
Mode = 8,9,10,12 (multimodal) this is when there are more than one mode
Range = highest number - lowest number
=15-9
=6
