Find the z-scores for the two scores in the given interval.

For the score x =391,

.
For the score x = 486,

Now you want the area (proportion of data) under the normal distribution from z = -1 to z = 0. The Empirical Rule says that 68% of the data falls between z = -1 to z = 1. But the curve is symmetrical around the vertical axis at z = 0, so the answer you want is HALF of 68%.
let the price of a slice of pizza be 'p' and that of soft drink be 's'
6 p + 5 s = 31.60............equation (i)
5 p + 4 s = 26.02............equation (ii)
6 p + 5 s = 31.60............×4
5 p + 4 s = 26.02............×5
24 p + 20 s = 126.4
25 p + 20 s = 130.1
p = 3.7
Answer = 3.7 Dollars
Answer:
f(1)=13
f(-9)=88
f(0)=0
f(-15)=20
The above mentioned are false statements
Step-by-step explanation:
f(1)=13 : false because "13" is out of range -40≤f(x)≤-10
f(-9)=88 : false because "88" is out of range -40≤f(x)≤-10
f(0)=0 : false because "0" is out of range -40≤f(x)≤-10
f(-15)=-20 : false because "-15" is out of domain -10≤x≤20
Answer:
Jake does have enough to buy a dog bone that cost $1.49
Step-by-step explanation:
6 quarters = $1.50
2 dimes = $0.20
1 nickel = $0.05
So add it all together: $1.50 + $0.20 + $0.05 = $1.75
