Answer:
w=-8
Step-by-step explanation:
1. add 6 to -10 (-4)
2. multilpy by 2 (-8)
Answer:
x = 45
y = 15
Step-by-step explanation:
Given that:
x = pineapple smoothies
y = mango smoothies
According to given conditions:
x + y = 60.................... eq1
$2.75 x + $3.25y = $172.50 ............ eq2
By taking eq1
x + y = 60
x = 60 - y
Putting value of x in eq2
$2.75 (60 - y) + $3.25y = $172.50
By simplifying
$165 - $2.75y + $3.25y = $172.50
Adding like terms:
$0.5y = $172.50 - $165
$0.5y = $7.5
Dividing both sides by $0.5
y =7.5/0.5
y =15
Putting value of y in eq 1
x + 15 = 60
x = 60 -15
x = 45
So there are 45 pineapple smoothies and 15 mango smoothies.
i hope it will help you!
Answer:
6:15 or 6/15
Step-by-step explanation:
if you put 12:30 in a ratio, it can be simplified by dividing by 2 and you get the ratio 6:15 or 6/15
The point would be (-2,1). x = -2, y = 1. I hope this helps, have a good day!
Answer: The proportion of new car buyers that trade in their old car has statistically significantly decreased.
Step-by-step explanation:
Since we have given that
p = 48% = 0.48
n = 115
x = 46
So,
So, hypothesis would be
So, test value would be
At 10% level of significance, critical value would be
z= 1.28
Since 1.28 < 1.72
So, we will reject the null hypothesis.
Hence, the proportion of new car buyers that trade in their old car has statistically significantly decreased.
