Answer:

option A

Step-by-step explanation:

let the hypotenuse be x

take 45 degree as reference angle and use cos rule

cos 45 = adjacent/hypotenuse

1/ $\sqrt{2$ = 6/x

do cross multiplication

6* $\sqrt{2$ = x *1

6 $\sqrt{2}$ = x

Which statement best explains whether △ABC is similar to △DEF?

Sati [7]

A). They are not similar, because 6/13 is not equal to 8/20

For triangles to be similar, the ratios of sides need to be the same (shortest to shortest, middle to middle, longest to longest). The shortest sides are 6 and 13, respectively, the middle ones are 8 and 20. Because 6/13 is not equal to 8/20, the triangles are not similar.

Solve the following quadratic equations using factoring.<br><br> C. X^2-10=9x

boyakko [2]

we can easily solve this one by splitting theiddle term

x2 - 9x -10

x2 -10x + x - 10

x(x - 10) 1( x - 10)

(x + 1) (x-10)

x = -1 or 10

The five-number summary for a data set is given below. 1.3 3.8 4.1 4.4 12.4 Using the 1.5 x IQR Rule, any data value _____ than

mixas84 [53]

Answer:

Any data value <u>less</u> than 2.9 should be flagged as a suspected outlier.

Step-by-step explanation:

We have been given the five-number summary for a data set is given below. 1.3 3.8 4.1 4.4 12.4. Using the 1.5 x IQR Rule, any data value _____ than 2.9 should be flagged as a suspected outlier. We are asked to fill in the given blank.

Our given points (1.3 3.8 4.1 4.4 12.4) represent minimum point, 1st quartile, median, 3rd quartile and maximum point.

First of all, we will find interquartile range by subtracting 1st quartile from 3rd quartile.

$IQR=4.4-3.8=0.6$

Using 1.5 x IQR Rule, we will get our outliers as:

$3.8-(1.5\times IQR)\Rightarrow3.8-(1.5\times 0.6)=3.8-(0.9)=2.9$

$12.4+(1.5\times IQR)\Rightarrow12.4+(1.5\times 0.6)=12.4+(0.9)=13.3$

Therefore, any data value less than 2.9 and greater than 13.3 should be flagged as a suspected outlier.
