<span>Given:
Matrix = 60 elements</span>
<span>To solve this, we need to
take into account that each row must contain the same number of elements. So, we
need to find which of the options do not divide evenly into 60 (the options are
30, 60, 10, and 18).
So we check each of the choices to see if 1 of them divides evenly with 60.
60 / 60 = 1 (divides evenly)</span>
60 / 30 = 2 (divides
evenly)
<span>60 / 10 = 6 (divides
evenly)
</span>60 / 18 = 3.3.3333333333333333333333333333333 (does not divide evenly)
Therefore, 18 cannot equal the number of rows of the matrix.
Answer:
388,800 ft^2.
Step-by-step explanation:
Scale = 1 : 180
Actual length, Ls = 180 × 4
= 720 ft
Actual width, Bs = 180 × 3
= 540 ft
Area of a rectangle = Ls × Bs
= 540 × 720
= 388,800 ft^2.
Answer:
120 posters
Step-by-step explanation:
300 - 60 = 240
240/2 = 120
Answer:
We can infer a cause-and-effect relationship because multiple variables were included.
Step-by-step explanation:
The multiple attributes for the divorced ones are
1) less physically active
2) an unhealthy weight,
3) smokers.
The attribute showing the % of the married is
1) death
So when we compare the two groups married and divorced we see different variables are involved in evaluating the percentage.
This shows a cause and effect involving multiple variables.
In cause and effect one variable is dependent and the other is independent.
The cause is the independent variable and effect is the dependent variable.
CAUSE EFFECT
Married Death
Divorced 1) less physically active
2) an unhealthy weight,
3) smokers.
As the normal distribution is symmetric the mean is (36 +
42) / 2 = 39
p(X < 42) = 1 - 0.063 = 0.937
From tables Φ (1.53) = 0.9370
From this time:
42 is 1.53 standard deviations above the mean
42 = 39 + 1.53s
1.53s = 3
Standard deviation is = 1.96
