The correct answer would be D. You find the range by subtracting the lowest value of a data set from the highest value of the data set.

<h2>Answer:</h2>

The standard deviation using the range rule of thumb of a data set with a minimum value of 176 and a maximum value of 237 is:

                             15.3

<h2>Step-by-step explanation:</h2>

We know that the range rule of thumb is used to find the estimate of the standard deviation with the help of the range of a data set.

It states that the standard deviation of a data set is equal to 1/4 times the range of a data set.

We have the minimum value of set= 176

and maximum value of set=237

Hence, the Range of data set= maximum value-minimum value

                                               = 237-176

                                               =  61

Hence, we have the standard deviation as:

                 \dfrac{61}{4}=15.25

           Hence, the answer is:

                  15.3

#10) Mrs. Sommer states that angle I is 65 degrees. Is she correct? why or why not​
Minchanka [31]

Answer: Mrs. Somner is correct.

Step-by-step explanation: In a triangle, the angles add up to 180 degrees. Since we know that Triangle ABC is equal to Triangle RST, we can assume that their angle values are equal as well. Angle A is 41 degrees, and Angle B is 74 degrees. This adds up to 115 degrees. If we subtract 115 from 180, we get 65. Therefore, Mrs. Somner is correct.

The 17th term of an Arithmetic sequence is 51. If the commons difference is 7, what is the first term ?
vovikov84 [41]

Answer:

The first term is:

  • a_1=-61

Step-by-step explanation:

The arithmetic sequence is defined by

a_n=a_1+\left(n-1\right)d

where

a_1 is the first term

d is the common difference

as

the 17th term of an arithmetic sequence is 51.

i.e. a_{17}=51

so

a_n=a_1+\left(n-1\right)d

a_{17}=a_1+\left(17-1\right)d        

51=a_1+\left(17-1\right)7         ∵ n = 17, a_{17}=51 , d=7

a_1+112=51                   ∵ \left(17-1\right)\cdot \:\:7=112

a_1=-61

Therefore, the first term is:

  • a_1=-61

Please help me The difference of two numbers is 9. If the larger number is one more than twice the smaller number, find the lage
Helen [10]

Answer:

17

Step-by-step explanation:

Let the larger number be represented by x

Let the smaller number be represented by y

from the question, the next equations can be gotten :

x - y = 9  equation 1

x = 1 + 2y equation 2

Substitute for x in equation 1

1 + 2y - y = 9

1 + y = 9

Collect like terms

y = 9 - 1

y = 8

Substitute for y in equation 1 and solve for x (the larger number)

x - 8 = 9

x = 9 + 8

x = 17

Three out of four student surveyed in a school said they will vote for nuncio for class president. Predict how many of the 340 s
elena55 [62]
3/4 is .75. translate that to percentages, and you get 75%. This means that it is likely that 75% of the 340 students in total will vote for Nuncio. 
write it out:
.75*340
solve:
255

about 255 students are likely to vote for Nuncio
