The model that illustrates the relationship is 4x=10.404x=10.40
The cost of each ice cream was x=\$2.60x=$2.60
Step-by-step explanation:
Let
x----> the cost of one ice cream
we know that
The linear equation that represent this situation is
4x=10.404x=10.40
solve for x
Divide by 4 both sides
x=10.40/4x=10.40/4
x=\$2.60x=$2.60
<h2>
Answer with explanation:</h2>
Let p represents the population proportion.
By considering the given information, we have
∵ the alternative hypothesis is two tailed , so the test is two-tailed test.
Given : For sample size :n= 130, 
Test statistic: 
P-value (two -tailed test)=
Since , the p-value (0.131) is greater than the significance level (0.03), so we accept the null hypothesis.
Thus , we conclude that we have sufficient evidence to support the null hypothesis that the true population proportion of Maryland students who have smoked marijuana is 29% .
Answer: 14.38%
Step-by-step explanation:
Worth of stock in Company A = $5990
Percent decrease = 20%
New worth = $5990 - (20% × $5990)
= $5990 - (0.2 × $5990)
= $5990 - $1198
= $4972
Worth of stock in Company B = $2450
Percent decrease = 8%
New worth = $2450 - (8% × $2450)
= $2450 - (0.08 × $2450)
= $2450 - $196
= $2254
Previous total worth = $5990 + $2450
= $8440
Total worth = $4972 + $2254
= $7226
The total percentage decrease in the investor's stock account will be:
= [($8440 - $7226) / $8440] × 100
=( $1214 / $8440) × 100
= 0.1438 × 100
= 14.38%
Answer:
Calculate the third missing measure.
Use the interior angle sum of a triangle.
