Answer:
40%
Step-by-step explanation:
To find a percent, divide the part by the total and multiply by 100.
To find the part, subtract 21 from 35 to find the people who left.
35 - 21 = 14
(14/35)*100 = p
.4 *100 = p
40 =p
40=10+2x where x is the number of dogs.
30=2x
x=15
Therefore she must walk 15 dogs
Hope this helps :)
Answer:
Standard score z=0.07
Step-by-step explanation:
The z-score, or standard score, represents an equivalent value for X but in the standard normal distribution, where μ=0 and σ=1.
For X=28.3 in a normal distribution with μ=26.3 and σ=28.1, the standard score can be calculated as:
This value is 0.07 standard deviations right to the mean.
In the picture attached, we have located the z-score.
The x-coord. of the vertex is halfway between the given zeros. Here, it'd be halfway between x=3 and x=9, which comes out to x = 6 (answer).
