Answer: 4/3
In dividing by fractions, you flip the latter one over. 2/3 * 2=4/3.
Answer:
0.2
Step-by-step explanation:
Given the data :
Day : Mon Tue Wed Thu Fri Sat Sun
# of sick days 22 11 16 17 21 28 25
The expected count of sick days taken on Saturday is obtained thus :
Expected count = (row total * column total) / overall total
Here, the table is just one way :
Hence, we use :
Observed value / total days
Hence,
Expected count on Saturday = sick days on Saturday / total sick days
Expected count on Saturday = 28 / (22+11+16+17+21+28+25)
Expected count on Saturday = 28 / 140
= 0.2
Therefore the answer is the first one
Answer:
let the price of a glass of milk be m and the price of seafood dinners to be s
A. for the first equation , we can see that
3m+5s =38.5 ........1
and second equation
m+2s= 15.15........2
B. 3m+5s= 38.5 ......1
m+2s=15.15 .......2
using substitution method
make m subject in eqn 2
m= 15.15 - 2s
put m in eqn 1
3(15.15-2s) +5s=38.5
45.45 -6s+5s =38.5
-6s +5s =38.5 -45.45
-s= -6.95
divide both sides by -1
s = $ 6.95
m= 15.15 -2s
m= 15.15- 2(6.95)
m= 15.15 -13.9
m=$ 1.25
therefore the price of a glass of milk is $1.25 and the price of a seafood dinner is $6.95
Answer:
B y ≥ 4x + 2
Step-by-step explanation:
1. find slope of the line: (y² - y¹) / (x² - x¹)
(0, 2) and (-1, -2)
(-2 - 2) / (-1 - 0) = -4 / -1 = 4
y = 4x + 2*
*+2 because that is the y-intercept as shown by point (0, 2)
2. the line is solid, therefore the inequality is ≤ or ≥. dashed line would mean < or >
3. the shaded region is on the right side of the line, so the values are greater than. therefore, you use ≥
4. final equation: y ≥ 4x + 2
