The likelihood of exactly 90 girls in 200 births is 0.0208. Since
this probability is lower than 0.05, this is an unlikely event. To see whether 90
girls is an unusually low number of girls, we need to think about the
probability of having 90 or fewer girls. Since P(90 or fewer girls) = 0.089>0.05,
this is not an unusually low number of girls.
Answer: 1110 grams

The single dilation of the shape is a dilation by a scale factor of 1.5 with center R
<h3>How to determine the dilation rule?</h3>
From the graph, we have the center of dilation to be point R.
This is so because R = R'
Also, we have:
R = (-1, -4)
S = (2, 0)
S' = (3.5, 2)
Calculate the distance RS and RS' using
This gives
Divide RS' by RS to determine the scale factor (k)
k = 7.5/5
k = 1.5
Hence, the single dilation of the shape is a dilation by a scale factor of 1.5 across point R

Answer:
1. 3:4 3/4 75% 0.75 three fourths
2. 0.25 1/4 25% 1:4 one fourth
3. 6 tenths = three fifths 3/5 60% 0.60 3:5
4. 1/3 one third 1:3 0.33 33%
5. 80% 4/5 4:5 four fifths 0.8
6. 19/20 95% 0.95 nineteen twentieths. 19:20
7. 1 and 5 tenths 1.5 1 1/2 150% 3/2
8. 7:8 7/8 0.875 87.5% seven eighths
I believe this is everything you asked but if I didn't give something just tell me and I'm 99.9% sure all of these are correct. Hope this helps!
