I think the first one c and the second one a
Answer:
3 left; 1 down
Step-by-step explanation:
You can determine the translation by identifying corresponding points on the two figures and counting the grid squares between them.
__
Here Q is a translation of P by 3 squares to the left and 1 square down.
Answer:
B) approximately normal with mean 2.3 and standard deviation 2
Step-by-step explanation:
Given the following :
Mean crimes per day = 2.3
Standard deviation = 2
Number of samples = 100
Sampling distribution of the mean:
According to the central limit theorem:
Sample mean = population mean
2.3 = 2.3
The standard deviation of the sample (s) : ratio of the population standard deviation and square root of the sample size.
s = population standard deviation / √sample size
s = 2 / √100
s = 2 / 10
s = 0.2
The central limit theorem also posits that once ths sample size is large enough, the sampling of the sample mean will be approximately normal.
Hence, the distribution is approximately normal, with mean of 2.3 and standard deviation of 0.2
D is the distance from moon to sun, and it's the hypotenuse of a right triangle.
Y is opposit to angle X
Sin (x) = y/d =
D = Y/sin(x)
1) tan 41°= 30cm divide by y cm
y= 30 divide by tan-1 41°
