210
Step-by-step explanation:
Since the three numbers have no factors in common, you can get the LCM by multiplying all three numbers.
Answer:
x = 5
Step-by-step explanation:
since the triangles are similar, their side lengths are proportional to each other.
12 / 20 = 3 / x
cross multiply to obtain
12x = 20*3
12x = 60
divide by 12
x=5
Answer:
69.1% of the woman spend less than $160
Step-by-step explanation:
Assuming that the random variable X= spend on beauty products by women during summer months distributes normally , then using the standarized variable Z:
Z= (X - mean / st. dev) = (160.00-146 )/28 = 0.5
then using normal probability tables for Z:
P(X<160)=P(Z<0.5) = 0.691 (69.1%)
thus 69.1% of the woman spend less than $160
The answer is $1.05 but this is only right if the posters cost the same amount as the markers.
Answer:
Step-by-step explanation:
Refer to attached for points
a) f(-1) = 3 as per graph
b) f(x) = 6
We add horizontal line through point y=6 to find intersections with the graph
Take x-values of those points. The points are x = -3, x = -2, x = 2
