(a) The shape of Jack's distribution of sample means is expected to be bell-shaped, with the mean being centered at the population mean of 50 and the standard deviation being much larger than the standard deviation of the population. This is because Jack is using larger sample sizes, which results in a more accurate estimate of the population mean.
The shape of Diane's distribution of sample means is expected to be similar to Jack's, but less pronounced. This is because Diane is using smaller sample sizes, which results in a less accurate estimate of the population mean.
(b) The mean of Jack's distribution of sample means is expected to be similar to the population mean of 50, but slightly larger due to the larger sample sizes. The mean of Diane's distribution of sample means is also expected to be similar to the population mean of 50, but again slightly larger due to the larger sample sizes.
(c) The standard deviation of Jack's distribution of sample means is expected to be smaller than the standard deviation of the population, because the larger sample sizes result in a more accurate estimate of the population mean. The standard deviation of Diane's distribution of sample means is also expected to be smaller than the standard deviation of the population, but again to a lesser extent due to the smaller sample sizes.

Answer:
so C but might be A
Step-by-step explanation:
Two quantities have a proportional relationship if they can be expressed in the general form y = kx, where k is the constant of proportionality. In other words, these quantities always maintain the same ratio. That is, when you divide any pair of the two values, you always get the same number k.
good luck, i hope this helps :)

3x+5x=32.
Step-by-step explanation:
start by adding like terms which would gice us
3x+5x=8x so,
8x=32 divide by 8 on both sides so we leave x by itself giving us x=4
Picture is below...........................
Answer:
C or A
thats all i know hope it helps
In triangle ABC, and C is a right angle. Find the value of the trig function find the sec(A) if C=25, B=20, A=15
Answer:
sec A = 5/4
Step-by-step explanation:
Sec of an angle is hypotenuse/adjacent side
In your problem, sec A = 25/20 = 5/4
It helps if you can draw a figure of the problem. Make sure you memorize the definition of each trig function

Write [tex]7^{-3}[/tex] as a fraction
Answer:
[tex]\frac{1}{343}[/tex]
Step-by-step explanation:
Using the rule of exponents
[tex]a^{-m}[/tex] ⇔ [tex]\frac{1}{a^{m} }[/tex] , then
[tex]7^{-3}[/tex]
= [tex]\frac{1}{7^{3} }[/tex] = [tex]\frac{1}{343}[/tex]

Solve the equation 3(f-1)+f= 1
Answer:
F = 1
Step-by-step explanation:
3(f-1) + f =
3(1 - 1) + 1 =
3(0) + 1 =
0 + 1 =
1
Therefore F = 1 hope this helped! Please give me a 5 star rating????
Answer: f=1
Step-by-step explanation: 3(f−1)+f=1
3(f−1)+f=1
(3)(f)+(3)(−1)+f=1
3f+−3+f=1
(3f+f)+(−3)=1
4f+−3=1
4f−3=1
4f−3+3=1+3
4f /4 = 4 /4
f=1

Answer:
the ratio of wheat cereal to rice cereal is 1:6 and the value is 1/6 or 0.16666
Step-by-step explanation:
if 1 1/2 = 1/4 then ?=4/4
since we know the value of 1/4 we multiply 1 1/2x4=6 and 1/4x4=1 so the ratio is 1:6. The value of the ratio is the quotient, and the quotient of 1 and 6 is 1/6 or 0.16666
hope this helps sorry if im wrong and have a blessed day :)

The highest point in Chicago is 735 feet above sea level. You can represent that numerically using .
Answer:
+735 feets
Step-by-step explanation:
Points or position above sea level are denoted with positive elevation values while points or positions below sea level are denoted by negative values. The sea level position itself could be viewed as a midpoint such as the position of 0 on a number line ; where distances to the right are positive and distances to the left are negative.
Hence, a point which is said to be 735 feets above sea level would have an equivalent numeric representation of +735 feets
Solve for the value of x
Answer:
x = 47°
Step-by-step explanation:
The secant- secant angle (x) is half the difference of the intercepted arcs, that is
x = [tex]\frac{1}{2}[/tex] (133 - 39)° = 0.5 × 94° = 47°

Answer:
I think it's 4
Step-by-step explanation:
if x+y is 7 and x-y is 3 then the answer is 4
Answer:
X=2, y=5
Step-by-step explanation:
X+y=7
x-Y=-3
————-
2x+ 0 =4
2x=4
x=2
solve for y using either equation
x+y=7
2+y=7
y=5
check answers by substituting x and y value in either equation:
x+y=7
2+5=7
7=7
or
x-y=-3
