Answer: V≈5.21 cm³
Step-by-step explanation:
To find the volume of a rectangular prism, you multiply the length, width and height.
Since we were given the length, width and height, we can directly multiply them together.
[multiply]
Now, we know that the volume is approximately 5.21 cm³ or 125/24 cm³.
x = 5.
I attached an image of my work!
Step 1: Subtract 8 from both sides
4x = 20
Step 2: Divide each side by 4
x = 5
Answer:
There is no difference in the mean number of times men and women send a Twitter message in a day
Zmen = 0.4
Zwomen = 0.2
Step-by-step explanation:
Null hypothesis: There is no difference in the mean number of times men and women send a Twitter message in a day
Alternate hypothesis: There is a difference in the mean number of times men and women send a Twitter message in a day
Z = (sample mean - population mean)/(sd ÷ √n)
Zmen = (25 - 23)/(5÷√1) = 2/5 = 0.4
Zwomen = (30 - 28)/(10÷√1) =2/10= 0.2
For a two tailed test, at 0.01 significance level, the critical value is 2.576
0.2 and 0.4 falls within the region bounded by -2.576 and 2.576, so we fail to reject the null hypothesis
There is no difference in the mean number of times men and women send a Twitter message in a day
Answer:
27 and 64
Step-by-step explanation:
3^3 is 27
4^3 is 64
Answer:
x = 17.51
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
tan theta = opp/ adj
tan 35 = x/25
25 tan 35 =x
x=17.50518
