Answer:
Step-by-step explanation:
8+1=9
8/9 ×100=800/9=88 8/9 %
1/9×100=100/9=11 1/9 %
Answer:
39%
Step-by-step explanation: First you make it into a fraction, 936/2400 then you divide the numerator(top) and denominator(bottom) 936÷2400=0.39
then you put the decimal 2 spots to the let and theirs your answer!!
Answer:
11) 153, 85, 238 12) 12, 15, 27
Step-by-step explanation:
To find the area of these shapes, you have to cut them into two seperate shapes as shown the in the image: Shape 1 and Shape 2
11) Let Shape 1 be the rectangle: 17×9=153
let Shape 2 be the triangle: ×10×8.5=42.5×2=85
Total area: 153 + 85 = 238
12) Let cut this shape vertically where you'll have a rectangle thats 3 by 4 and a rectangle that's 5 by 3
Shape 1: 3×4=12
Shape 2: 5×3=15
Total area: 15 + 12 = 27
Answer:
For the first equation
Twice a number added to a smaller number is 5 is written as
2x + y = 5
For the second equation
The difference of 5 times the smaller number and the larger number is 3 is written as
x - 5y = 3
Hope this helps you
Answer:
The mean waiting time of all customers is significantly more than 3 minutes, at 0.05 significant level
Step-by-step explanation:
Step 1: State the hypothesis and identify the claim.
Step 2: We calculate the critical value. Since we were not given any significant level, we assume , and since this is a right tailed test, the critical value is z=1.65
Step 3: Calculate the test statistic.
Step 4:Decide. Since the test statistic , 2 s greater than the critical value, 1.65, and it is in the critical region, the decision is to reject the null hypothesis.
Step 5: Conclusion, there is enough evidence to support the claim that the mean is greater than 3
