The hypotenuse of a right triangle measures 58 cm and one of its legs measures 42 cm. What is the length of the missing leg? 10

Nutka1998 [239]

If the hypotenuse is 58cm, and one of the others legs is 42cm the answer would be 40cm

Explanation:

Here you have to use the formula

${a}^{2} + {b}^{2} = {c}^{2}$
Then you have to pose the formula in terms of one of the legs, so:

${a}^{2} = {c}^{2} - {b}^{2}$
$a = \sqrt{ {c}^{2} - {b}^{2}}$
So when you change the letter for numbers you have that:

$a = \sqrt{ {58}^{2} - {42}^{2} }$

a=40

Evaluate the limit assuming that limx→−5f(x)=17limx→−5f(x)=17 and limx→−5g(x)=22limx→−5g(x)=22. (use symbolic notation and fract

Gemiola [76]

In this question it is given that

$\lim_{x->-5}f(x)=17, \lim_{x->-5}g(x)=22$

And we have to find the value of the given limit

$\lim_{x->-5}(23f(x)+3g(x))$

Using properties of limit, first we separate the two functions, that is

$23\lim_{x->-5}f(x)+3\lim_{x->-5}g(x)$

Substituting the values of the given limit,

$23(17)+3(22)=457$

Robinâ€™s scores: 99, 108, 102, 107, 119 Mean = 107; MAD = 5. 2 Evelynâ€™s scores: 125, 137, 138, 145, 145 Mean = 138; MAD = 5.

stiks02 [169]

The mean absolute deviation (MAD), refers to the mean of the data's absolute deviations around the data's mean.

The MAD implies that Evelyn scores are more spread out than Robin scores.

The given parameters:

Robin scores = 99, 108, 102, 107 119
Mean of Robin score, = 107
Mean absolute deviation = 5.2
Evelyn scores = 125, 137, 138, 145
Mean of Evelyn score = 5.6

The mean absolute deviation (MAD), refers to the mean of the data's absolute deviations around the data's mean. It implies the absolute distance from the mean of the data set.

The absolute distance of Evelyn scores from her mean score is greater than the absolute distance of Robin scores from his mean score.

Thus, we can conclude that Evelyn scores are more spread out than Robin scores.
