Tammy wants to grow cube watermelons like the ones that are sold in japan. she found the following directions on the internet: “you will need 6, square, sheets of polycarbonate plastic. the volume of the cube when assembled will be 512in . see picture below” what is the length of the side of the cube?
∛(512 in³) = 8 in.
2. All of the above 3. B 4.A 5.B 6.C
Apply Newton's second law to the box in the y direction.
∑F = ma
2 T sin 60° − mg = 0
2 T sin 60° = mg
T = mg / (2 sin 60°)
T = (55 kg) (9.8 m/s²) / (√3)
T ≈ 311 N
A. the light is being scattered
it is most commonly called dis-figuration and just like if you put a pencil in a cup of water it looks like its been cut in half.
AB= 8/Cosine 60 degrees
AB=8/Cosine 60 degrees
Answers are I two options
THe question is about the confidence interval of difference of two groups
From the given data we find that mean difference =-25.82
Sample size of group I = 41 and group 2 =36
Hence for difference of means degree of freedom = 41+36-2=75
Since df >30, z critical 99% i.e. 2.58 can be used
Std error for difference =2.280
Hence for 99% confidence interval
margin of error = ±2.58(2.28)
Confidence interval lower bound =-25.82-5.91 =-31.73
Upper bound = -25.82+5.91 =-19.91
From the given five values we find that
24.12 and 26.71 lie within this interval
Figure 4: Square
Figure 1: Parallelogram
Figure 2: Rectangle
Question 1: If they're not similar it can't be the same shape but if they have the same corresponding angles it has to be either a rectangle or a square. It can't be a rectangle so it must be a square.
Question 2: Can't be similar so it can't be the same shape. The only two shapes with side lengths proportional are the parallelogram and the rectangle. It can't be the rectangle so it must be the parallelogram.
Question 3: If it's similar it has to be the same shape so the answer must be the rectangle.
Given the particulars about number of books read by males and females in a high school in the past year.
Males had a mean of 8.4 with std dev 2.3
Females had a mean of 5.9 and std dev 1.8
Sample size was 107 for males and 120 for females
Mean difference between boys and girls = 8.4-5.9 = 2.5
Std error for difference =0.260
For 95% confidence interval
Margin of error =1.96(STd error)
Hence confidence interval for difference of means Males - Mean females
Since mean difference is positive males read more books than females
There is a 95% probability that males seniors at this high school read between 1.99 and 3.01 more books than females
answer: you need the equation in the question so i can answer it
