Step-by-step explanation:
1/4 of 100 is 25.
100/4 is 25
9) yes it is similar : it does not have to be congruent
10) scale factor: 2 (inside) :3 (outside)
11) ratio: 16 (inside) : 24 (outside)
12) Yes they are similar
hope this helps
Step-by-step explanation:
√9x2√18y2. √9=3. √x2=x. √18=√9×2=3√2. √y2=y. Therefore √9x2√18y2=3x3√2y = x√2y.
Answer:
d. 52.5 million cases
Step-by-step explanation:
from the data output in the question, we have the regression equation to be
log y = -151.281 + 0.076577x
y is the number of hiv cases which is in millions
x is the year of the hiv case
x = 1998
we put the value of x in the regression equation
log y = -151.281 + 0.076577(1998)
log y = -151.281 + 153.000846
log y = 1.719846
since the result is in log form,
y = 52.5 million cases
The values on the number line are between 0 and 1. There are 8 points from 0. The distance between two consecutive points would be
1/8 = 0.125
Since the given point is on the second point after 0, the equivalent value would be
2 * 1/8 = 2/8
Dividing the numerator and denominator of 2/8 by 2, we have 1/4
Thus, the two equivalent fractions for the point on number line are
2/8 and 1/4
