What is the mode of the data set?

Mathematics
1 answer:
saw5 [17]3 years ago
5 0

Answer: 92 which is choice D

Look at the right side of values for the digit that comes up the most. In this case, it would be '2' in the second row. It shows up 3 times. Those leafs pair up with the stem of 9 to form the full value 92. So we have 92 show up three times which is the most frequent value.

The data set would expand out to

85, 88

92, 92, 92, 98

105, 106, 106, 109

113

126, 127

Answer:

(0,9) for y-intercept

perp.: (-1/2)= m

y - 9 = (-1/2)x - 0

y = (-1/2)x + 9

Which graph represents the function f(x)=-|x|-2 ?
Elden [556K]

Answer:

The graph of given function is shown below.

Step-by-step explanation:

The absolute parent function is g(x)=|x|. The graph of parent function is a V-shape d and vertex of the function is origin.

The given function is

f(x)=-|x|-2              .... (1)

The vertex from of an absolute function is

f(x)=a|x-h|+k          .... (2)

where, a is a constant and (h,k) is vertex of the function.

From (1) and (2) we get

a=-1,h=0,k=-2

The value of a is -1. The value of a is negative it means the graph of parent function reflect across x-axis.

The vertex of the function is (0,-2). It means the graph of parent function shifts 2 units down.

The graph of given function is shown below.

Explain 2/2=1. write abother fraction that is equal to 1.
NISA [10]
Division can be looked at as breaking things into parts. For example, with you 2 ÷ 2 = 1 that can be looked at as you have two chocolate bars and 2 people who want those chocolate bars. How can you fairly give those 2 people 2 chocolate bars? Well you would give them 1 each? It'd be the same thing with 5 people and 5 chocolate bars. Any number divided by itself with always be one, no matter what. Unless you have 0/0 or infinity/infinity , but those are different scenarios.

a study on the latest fad diet claimed that the amounts of weight lost by all people on this diet had a mean of 20.8 pounds and
NikAS [45]

The standard deviation of the sampling distribution of the sample means is 20.8

What is Sample mean?

A sample is just a small part of a whole. For example, if you work for a polling company and want to know how much people pay for food a year, you aren’t going to want to poll over 300 million people. Instead, you take a fraction of that 300 million (perhaps a thousand people); that fraction is called a sample. The mean is another word for “average.” So in this example, the sample mean would be the average amount those thousand people pay for food a year.

The sample mean is useful because it allows you to estimate what the whole population is doing, without surveying everyone. Let’s say your sample mean for the food example was $2400 per year. The odds are, you would get a very similar figure if you surveyed all 300 million people. So the sample mean is a way of saving a lot of time and money.

Given that,

mean = \mu = 20.8

standard deviation =  σ   =  4.2

n=89

So, The sampling distribution of the sample means is:

\mu\bar x = \mu=20.8

Hence,

The standard deviation of the sampling distribution of the sample means is 20.8
