Answer:
0.3175
Step-by-step explanation:
z=-1.25 from table is .1056
z=.80 from table is .7881
subtract from each other =.6825
Subtract from the whole is 1-.6825=0.3175
Answer: Sorry i only speak english
Step-by-step explanation:
Answer: 7
Step-by-step explanation:
3x (4 - 2) + 1
3x (2) + 1
6 + 1
7
To find whether or not the ratios are proportional, simplify. The first ratio is already simplified, so simplify the second one. to do this, find what factors 24 and 35 have in common.
Factors of 24: 1, 2, 3 ,4, 6, 8, 12, 24
Factors of 35: 1, 5, 7, 35
It looks like there are now common factors between 24 and 35. For the ratios to be proportional, they have to have the same value. If 24/35 can't be simplified to 4/7, the factors are not proportional.
So, to answer the question: No, the ratios are NOT proportions. I hope this helps and have a great rest of your day!
