Answer:
d. Reject H0 if t < -1.6604
Step-by-step explanation:
This is a hypothesis test for the population mean.
The claim is that the mean number of tissues used during a cold is significantly less than 60.
Then, the null and alternative hypothesis are:
The significance level is 0.05.
The critical value for a level of significance is α=0.05, a left-tailed test and 99 degrees of freedom is tc=-1.6604.
The decision rule is that if the test statistic is below tc=-1.6604, the null hypothesis is rejected.
Linear that is it ugh i needed to make it 20 characters ok
Answer:
10
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
To find the volume, we should find the area of the triangle, the multiply by the depth of the object.
Area of Triangle = 1/2 * base * height = 5.7cm * 7.6cm / 2 = 21.66cm^2
Multiplying this by the depth of the object and we find:
21.66cm^2 * 4.8cm = 103.968cm^3
which we can round (if needed) to 103.97cm^3
