Answer:
11.4 mixture:26 and 2/3
7.8 mixture: 53 and 1/3
Step-by-step explanation: Sorry if this is hard to underestand. This is my first answer. This is a RSM question that has been checked.
11.4+7.8=9
x+80-x=80
Multiply
11.4x+624-7.8x=720
3.6x=96
1.2=32
0.6x=16
6x=160
x=26 2/3
80-26 2/3= 53 1.3

Answer:
She runs for 1.6 hours
Step-by-step explanation:
For this, one way to do it is to just set 1 hour over 4 miles equal to x hours for 6.4 miles. The reason this is done is because if the speed is constant that means the rate stays the same, which means the ratio of miles to hours should always be the same, so the two ratios must be equivalent.
1/4 = x/6.4
Multiply both sides by 6.4 to get x by itself:
6.4/4 = x
1.6 = x
Hope that helps!

Answer:
.0668
Step-by-step explanation:
Formula:
z=(x-average)/standard deviation
(2.5-2.8)/.2= -1.5
Go to a ztable and find the value for 1.5 (.9332) and take the compliment of this (we can do this because the normal distribution is symmetrical)
1-.9332= .0668
