Answer:
with 0.10 level of significance the P-VALUE that would be used in the hypothesis claim is 0.05%
Step-by-step explanation:
In hypothesis testing in statistics, we can say that the p-value is a probability of obtaining test results when we assume that the null hypothesis is correct.
The p-value is the probability that the null hypothesis is true.
A p-value less than or equals to 0.05 is statistically significant. It shows strong evidence against the null hypothesis, meaning there is less than a 5% probability the null is correct and clearly we can say that the results are random.
Answer:
$17.28.
Step-by-step explanation:
In the expression, d represents the number of drinks she orders and t represents the number of toppings.
In this case, she orders 4 drinks and 3 toppings, so d = 4 and t = 3.
0.90(2.25d + 1.40t + 6)
= 0.9(2.25 * 4 + 1.4 * 3 + 6)
= 0.9(9 + 4.2 + 6)
= 0.9 * 19.2
= 17.28
So, the total cost for Lindy and her friends will be $17.28.
Hope this helps!
Answer: {(5,0), (3,4)}
Step-by-step explanation:
You can apply the Substitution method:
- Solve for y from the second equation.
- Substitute into the first equation and solve for x.
Then:
(Remember that: 
)
Substitute the values obtained into one of the original equation and solve for y:
The solution set is: {(5,0), (3,4)}
X_>-2*4
x_>-8
Answer: x> -8
