Answer: C
Step-by-step explanation: The $25 is added on to the constant rate of $5.25. This means that it would be $5.25 + $25 > $250
Answer:
cost of ice cream cones = $1.75
cost of ice cream sandwiches = $2.25
Step-by-step explanation:
Let
x = cost of ice cream cones
y = cost of ice cream sandwiches
3x + 4y = 14.25 (1)
5x + 2y = 13.25 (2)
Multiply (2) by 2
10x + 4y = 26.50 (3)
3x + 4y = 14.25 (1)
Subtract (1) from (3)
10x - 3x = 26.50 - 14.25
7x = 12.25
x = 12.25/7
x = $1.75
Substitute x = 1.75 into (1)
3x + 4y = 14.25
3(1.75) + 4y = 14.25
5.25 + 4y = 14.25
4y = 14.25 - 5.25
4y = 9
y = 9/4
y = $2.25
no because the answer is that a whole number
Answer:
Null, H0 : μ = 417
Alternative, H1 : μ ≠ 417
Step-by-step explanation:
Given that :
The mean grams by a bag filling machine μ = 417
Hence, the null hypothesis is That bag filling machine works correctly at 417 grams setting
The alternative hypothesis will negate the null ; In this question, the alternative hypothesis looks at the possibility of either overfill or underfill, which In straightforward terms means that the 417 g ram setting for the bag filling machine is incorrect.
Hence,
Null, H0 : μ = 417
Alternative, H1 : μ ≠ 417
The area of the minor sector DFE is gotten as; D: 66.1 square cm
<h3>How to find area of sector?</h3>
Formula for area of sector is;
A = (θ/360) * πr²
We are given;
minor angle; θ = 100°
radius; r = 8.7 cm
Thus;
A = (100/360) * π(8.7²)
A = 66.1 square cm
