we know that

Normal distribution:

The normal distribution is a very common continuous probability distribution

A probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean

now, we will check each options

option-A:

we know that number of coupons will always be counted

so, it is discrete in nature

so, this is not normal distribution

option-B:

we know that

the weights of the pumpkins that are delivered to a supermarket can be any values

so, this will be continuous in nature

so, this is normal distribution

option-C:

the number of raisins in each 8-oz box of raisins at a supermarket

number will always be counted

so, this is discrete in nature

so, this is not normal distribution

option-D:

the amount of time customers spend waiting in the checkout line at a supermarket

time can be decimal or number

so, this is continuous in nature

so, this is normal distribution

The bases of a circular cylinder are two ___ circles.
Blababa [14]
Well,

A cylinder is actually a special type of prism.  A prism is a 3-D figure made by taking a simple closed plane curve and translating it across space in a certain direction and for a given distance and then connecting the preimage and the image.  A cylinder is just a prism made with a circle.

We know from translations that the image is congruent to the preimage.  Thus, the bases of a (circular) cylinder are two congruent circles.

Find an expression for the nth term ( tn ) in each of the following sequences:
Alexandra [31]

Answer:

The expression for the nth term is Tn = 8n -7

Step-by-step explanation:

Here, we are to find an expression for the nth term of the sequence.

Mathematically, the nth term of an arithmetic sequence can be expressed as;

Tn = a + (n-1)d

for T2, the equation is

a + d = 9

for T4, the equation is

a + 3d = 25

we can substitute the equation of T2 into T4 but we first need to rewrite T4

a + d + 2d = 25

9 + 2d = 25

2d = 25 -9

2d = 16

d = 16/2

d = 8

now since a + d = 9

a = 9-d

a = 9-8

a = 1

So the expression for the nth term would be;

1 + (n-1)8

1 + 8n - 8

= 8n -8+1

= 8n -7

What value of c makes the polynomial below a perfect square? x^2+10+c
Inessa05 [86]

Answer: Hi there

To find the last term in order to obtain the perfect square, take the middle term, divide it by 2, and take its square. 

10 ÷ 2 = 5

5^2 = 25

Thus, the equation would be x^2 + 10x + 25

The answer is 25
