Red=2 nits
blue=4 nits
if 6liters=blue=4 units
divide 2
3 liters=2 units=red
red=3 liters
Answer: 32
Step-by-step explanation:
4 cubed 2 divided by 4
Simply is
4 to the power 3 multiplied by 2 divided by 4
4*4*4*2/4
128/4= 32
Answer:
Step-by-step explanation:
In parallelogram, opposite sides are parallel and equal
3x + 7 = 5x -17
3x - 5x = -17 - 7
-2x = - 24
x = -24 /-2
x = 12

Solve using distributive property

can be rewritten as 
So:

Factorize:

Now, we can apply distributive property on the expression;

Hence, the above is an equivalent expression.
Solving further, we have


Answer:
A birth weight of 3.9998kg has a z-score of 0.81.
Step-by-step explanation:
Problems of normally distributed samples can be solved using the z-score formula.
In a set with mean
and standard deviation
, the zscore of a measure X is given by:

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:

What birth weight has a z-score of 0.81?
This is X when Z = 0.81. So:




A birth weight of 3.9998kg has a z-score of 0.81.
