Answer:
180 seconds
Step-by-step explanation:
1 minute = 60 seconds
120 * 3 = 360
60 * 3 = 180
Answer:
(2,0)
Step-by-step explanation:
To find the x intercept, set y =0 and solve for x
5x-y =10
5x -0 = 10
5x=10
Divide by 5
5x/5=10/5
x=2
(2,0)
Answer:
yes, we can reject the hypothesis
Step-by-step explanation:
The null hypothesis
H0 = mean weekly food budget for all households in this community is $98
Let´s find z
z= (x – mean) / standard deviation / √sample size
z = (100 – 98) / 10 / √100
z = 2
Using a Z table we can find probability
P (z>2) = 0.0228
Since P < α , results are significant and we can reject the hypothesis
1.First multiply 4(2y) and 4(6) which gives you (8y-24).
2.Then write out the whole problem: (15y-8y-24).
3.Subtract 15y-8y first since they have equal terms. That will give you 7y.
4.Now you have (7y-24).

Answer:
3(x+7)/4
Step-by-step explanation:
Three times the sum of a number and 7 will be 3(x+7) because it is triple the amount of that unknown number plus seven and then after that we divide what we get from 3(x+4) and divide that by 4 which makes the equation 3(x+7)/4.
