Use technology or a z-score table to answer the question.

Mathematics
1 answer:
matrenka [14]3 years ago
4 0

Answer:

D

Step-by-step explanation:

I usually use a z-score table, but you can do this with a calculator.

If we go to a z-score table, we first look up the first two digits (in this case, 2.8) in the far left column.  Then we find the hundredths digit in the top row (0.07).  Where they intersect is P(z < 2.87).

P(z < 2.87) = 0.9979

Answer D.

2) The second graph is the graph of f(x) traslated 5 units upward, then the equation of this graph is: y=x^2+5

3) The third graph is the graph of f(x) traslated 5 units downward, then the equation of this graph is: y=x^2-5

4) The fourth graph is the graph of f(x) traslated 5 units to the right, then the equation of this graph is: y=(x-5)^2

1) What weight of sugar syrup would you get if you made 70% sugar syrup from 350g of sugar
Soloha48 [4]
<span>1) If we mix up 350g of sugar with some water to make 70% sugar syrup, then 70% of sugar syrup weight is equal to weight of sugar, i.e. 350g
   total weight of sugar syrup will be 350 * 100/70 = 500 g
        2) Similarly, total weight of 30% sugar syrup made with 75g of sugar will be 75 * 100/30 = 250 g</span>
