Answer:
0.89736
Step-by-step explanation:
We solve this question using z score formula
Z score = x - μ/σ
x = raw score
μ = population mean
σ = population standard deviation
Hence,
x = 258, μ = 220, σ = 30
Z = 258 - 220/30
=1.26667
Probability value from Z-Table:
P(x<258) = 0.89736
Therefore, the probability that his weights is less than 258 kg is 0.89736
600kb in 24 seconds to find out how many kbs per second divide by 24
600/24 is 25kb
I think the answer is either b or c i am not sure
Answer:

Step-by-step explanation:
To derive the function rule in slope-intercept form,
, we need to find the slope, m, and the y-intercept, b, of the graph given.
Using two points on the line, (-1, 2) and (0, -2), find slope (m) as shown below:

m = -4
The line intercepts the y-axis at y = -2, therefore the y-intercept, b, = -2.
Substitute m = -4, and b = -2 into
.
The function rule in slope-intercept form would be:


Order set...{160,165,170,240,240,450}
The "mean" is the arithmetic average of the elements...
mean=(160+165+170+240+240+450)/6=237.5
The "median" if the set has an odd number of terms is the middle term, if the set has an even number of terms, it is the average of the middle two terms.
In this case the number of elements is even and the middle two terms are 170 and 240 so:
median=(170+240)/2=205
The "mode" is the term which appears the most in the set, so in this case:
mode=240
