Answer:
Q1:14 Q2:8903.5
Step-by-step explanation:
I find that using equations to solve problems makes it a lot easier.
The first company's equation would be y=5743+225.75x because 5743 is the set fee and 225.75 is for each ton of sugar. The second company would be y=7500+100.25x for the same reasons.
So we need to find a value of x that works for each company and a value of y that is the same for the cost.
Now we combine them.
Solve for x:
5743+225.75x=7500+100.25x
-5743 -5743
225.75x= 1757+100.25x
-100.25x -100.25x
125.50x=1757
/125.5 /125.5
x=14
Therefore, for Q1, the answer is 14.
Now we solve for y by substituting x for 14.
5743+225.75(14)
5743+3160.5
8903.5
We can also check this with the other equation
7500+100.25(14)
7500+1403.5
8903.5
So therefore, the answer to Q2 would be 8903.5.
Answer:
its y=2x so yaa thats ittt
Given Information:
Confidence level = 95%
Error = 0.07
Mean = μ = 8.1
Standard deviation = σ = 2
Required Information:
Sample size = n = ?
Answer:
Sample size = n ≤ 2209
Step-by-step explanation:
The sample size required to create the specified confidence interval is given by
error ≤ z*(σ/√n)
Where z is the corresponding z-score of 95 percentile, n is the sample size and σ is the standard deviation and error is no more than 0.07
√n ≤ z*σ/error
n ≤ (z*σ/error)²
The z-score for 95% confidence level is 1.645
n ≤ (1.645*2/0.07)²
n ≤ 2209
Therefore, a sample size of n ≤ 2209 is required to create a 95% confidence interval with an error of no more than 0.07.
The area of the shape shown in the image which is in the shape of kite figure is 168 squared centimeters.
<h3>What is the area of the kite figure?</h3>
The area of the kite figure is half of the product of its diagonals. Area of kite figure can be find out using the following formula.
Here, p and q are the diagonals of the kite.
The length of the first diagonal of the kite figure is,
p=6+15
p=21 cm
The length of the second diagonal of the kite figure is,
q=8+8
q=16 cm
Thus, the area of kite figure is:
Thus, the area of the shape shown in the image which is in the shape of kite figure is 168 squared centimeters.
