More than one triangles of different triangles of different sizes can be constructed with angle measurement of <span>134°,10°,36°</span>
DedPeter [7]3 years ago
4 0

Answer:

More than one triangle

Step-by-step explanation:

we know that

If two triangles are similar, then the ratio of its corresponding sides is equal and its corresponding angles are congruent

In a triangle the sum of its internal angles must be equal to 180 degrees

In this problem

The sum of the internal angles is equal to

134\°+10\°+36\°=180\°

so

By the sum of the internal angles, we can construct a triangle

but

By the length of the sides keeping the same internal angles, we can construct infinite similar triangles

Which statements are true about the median of a data set?
Leto [7]

Answer: Third and fifth option

3) The median is the number in the middle on an ordered set of data.

5) To find the middle of an even data set, find the average of the two middle numbers.

Step-by-step explanation:

Given a set of data ordered from lowest to highest, the median of the data is the number that is in the middle. In other words, it is a number x for which it is true that 50% of the data is greater than x and the other 50% of the data is less than x.

For example, for the following set of 7 data:

2, 3, [5], 8, 13

the median is 5.

If the data number is even, for example 10 data:

3, 5, 9, 12, [19, 21], 33, 35, 40, 69

The median is<u><em> the average between the two data that are in the middle </em></u>

\frac{19 +21}{2} = \frac{40}{2} = 20

Note that the median only represents a partition of the ordered data set. Therefore, it is <em><u>not affected by outlier.</u></em> For example

2, 4, 4.5, 4.8, 5          Median = 4.5

2, 4, 4.5, 67, 1506     Median = 4.5

The median does <u><em>not represent the difference between the highest and the lowest data. </em></u>

Therefore the correct affirmations are:

3) The median is the number in the middle on an ordered set of data.

5) To find the middle of an even data set, find the average of the two middle numbers.

Help me graph this pls!<br> y=-(2)/(3)x+2
WINSTONCH [101]

Answer:

You start at the Y Intercept of 2, then you go up 2 units, and to the left 3 units.  You will then make a line.

Step-by-step explanation:

Since it is not a negative slope, it will point to the top right corner.

A simple random sample of months of sales data provided the following information: Month Units Sold a. Develop a point estimate
Gnom [1K]

Answer:

a) X[bar]=93

b)S=5.39

Step-by-step explanation:

Hello!

<em>A simple random sample of 5 months of sales data provided the following information: Month: 1 2 3 4 5 Units Sold: 94 100 85 94 92 </em>

<em />

<em>a. Develop a point estimate of the population mean number of units sold per month. </em>

The variable of interest is:

X: Number of sales per month.

A random sample of n=5 months was taken, for each month, the number of units sold was recorded. To calculate the mean of the sample you have to add all the observed frequencies (Units Sold) by the sample size (n)

X[bar]= ∑X/n= 465/5=93

You can say that, on average, 93 units were sold over the 5-month period.

<em>b. Develop a point estimate of the population standard deviation.</em>

To calculate the sample standard deviation you have to calculate the variance and then its square root:

S^2= \frac{1}{n-1}[sumX^2-\frac{(sumX)^2}{n} ]

∑X= 465

∑X²= 43361

S^2= \frac{1}{4}[43361-\frac{(465)^2}{5} ]= 29

S= √29= 5.385≅ 5.39

I hope this helps!

Ricky is packing food for camping trip. He has 24 granola bars and 30 protein bars. Ricky wants to make identical bags. Each wil
dimaraw [331]

Answer:

6

Step-by-step explanation:

first, we need to find the GCF (Greatest Common Factor) which is the highest number that can go into every number in the equation (In this case, those numbers are 24 and 30)

The GCF for this would be 6, meaning that there would be 6 bags with and equal amount of granola bars and protein bars.
To be more specific, every bag would have 4 granola bars and 5 protein bars.
