Answer:

The missing side is 7

Step-by-step explanation:

The smaller triangle has the same exact angles and the bigger one. If you notice each side with a value is three times the smaller one. 8m times three equals 24m. So if we divide 21 by 3 we get 7

What is the solution to this equation?<br> 6x + 10 - 2x= 7 + 23
Strike441 [17]

Answer:

\boxed{x=5}

Step-by-step explanation:

First, you need to combine like terms in order to begin simplifying. This is done by subtracting 2x from 6x. Also, add 7 to 23.

6x + 10 - 2x = 7 + 23

4x + 10 = 7 + 23

4x + 10 = 30

Now, you have a two-step equation. Subtract 10 from both sides, and then divide by 4.

4x + 10 = 30

4x = 20

x = 5 is the final answer.

The accompanying data on IQ for first-graders at auniversity lab school was introduced in Example 1.2.82 96 99 102 103 103 106 1
almond37 [142]

Answer:

Mean = 113.72

The estimator of 113.72 is point estimate used for the  conceptual population of all first-graders in this school

Step-by-step explanation:

Data provided in the question:

Data:

82 96 99 102 103 103 106 107 108 108 108 108 109 110 110 111 113 113 113 113 115 115 118 118 119 121 122 122 127 132 136 140 146

Number of data = 33

In the hint it is also given that the sum of the data value i.e ∑x = 3753

Now,

Point estimate of mean is given as;

Mean = \frac{\textup{Sum of all the data values}}{\textup{Total number of data value}}

or

⇒ Mean = \frac{\textup{3753}}{\textup{33}}

or

⇒ Mean = 113.72

Hence,

The estimator of 113.72 is point estimate used for the  conceptual population of all first-graders in this school
