Answer:
75 squares
Step-by-step explanation:
ovals is proportional to the number of squares
75 ovals = 75 squares * constant of proportionality ( this could be any number)
so for 75 ovals we can have
75 squares ,
or 2*75 = 150 squares ,
or we could have .6 *75 = 45 squares
First, find out how many pounds in a ton. 2000 pounds are in one ton. It is 70 cents for 1 pounds, multiply that by 2000 to see how much it costs for a ton. It would get you $1,400. Next, multiply 1,400 by 5 to see how much it is for 5 tons. It cost approximately 7,000 dollars.
Answer:
Step-by-step explanation:
We want to determine a 95% confidence interval for the mean salary of all graduates from the English department.
Number of sample, n = 400
Mean, u = $25,000
Standard deviation, s = $2,500
For a confidence level of 95%, the corresponding z value is 1.96. This is determined from the normal distribution table.
We will apply the formula
Confidence interval
= mean ± z × standard deviation/√n
It becomes
25000 ± 1.96 × 2500/√400
= 25000 ± 1.96 × 125
= 25000 ± 245
The lower end of the confidence interval is 25000 - 245 =24755
The upper end of the confidence interval is 25000 + 245 = 25245
Therefore, with 95% confidence interval, the mean salary of all graduates from the English department is between $24755 and $25245
Total drops = 4 + 10 = 14
Total cherry drop = 4
P(cherry) = 4/14 = 2/7
Answer:P(Cherry) = 2/7
Hey!
--------------------------------------------------------
Solution:
Ratio is 4/1
Add.
4 + 1 = 5
Divide.
150 / 5 = 30
Multiply for Ivan.
30 x 4 = 120
30 x 1 = 30
Check.
120 + 30 = 150
Subtract.
120 - 30 = 90

Answer:
Ivan has £90 more than Tanya has!
