Answer:
Miriam walks for 1.8 miles and jogs for 0.9 miles.
Step-by-step explanation:
The path for jogging is 2.7 miles.
One lap of the path, that is 2.7 miles, is completed by Miriam by jogging part and walking part.
Let the jogging part be x miles.
It is given she jogs half the distance she walks , therefore we can say that she walks for 2x miles.
So we can say that 2x + x = 2.7 miles ⇒ 3x = 2.7 miles
⇒ x = 0.9 miles.
Therefore Miriam walks for 1.8 miles and jogs for 0.9 miles.
In any function y = f(x) , set of all possible values of x define the domain of f(x), in the graph The curve in terms of x-axis(in 1st & 3rd quadrant) goes from -4 to -2(doesnt include -2).
So domain = [-4, -2)
Similarly, in 2nd and 4th quadrant, for x-axis
It goes from 2 to 5 (doesnt include 2 & 5)
So domain = (2, 5)
Hence,
Domain of the f(x) is [-4, -2) U (2, 5).
Range tells the possible values of y, for this function it goes from -5 to +3(doesnt include 3).
Range is [-5, 3)
The answer is 27 (54 divided by 2 equals 27; 27 is equal to 27 and adds up to 54 when combined with another 27)
Z-score=(score-mean) standard deviation
test A : z(A)= (90-64)/8=3.25
test B: z(B)= (95-60)/10=35/10=3.5
she did better on test B,
answer is A
