I got 0......when I added them all up I got 0 so dividing would still give me 0

I got 0.

Why: To find the mean of a set of numbers, you need to add all the numbers that are given. Once you find the numbers that are given, divide by the amount of numbers given. Basically, add -1, 4, 0, -1, -1, -1, then divide the outcome by 6.

What is the equation of the line that contains the point (-1, 4) and has a slope of 3?

sertanlavr [38]

Let's write the equation with formula:-

$\boxed{ \sf \: formula : y -y_{1} = m(x - x_{1})}$

Where,

x1 is -1 and y1 is 4 and m is 3

$\tt \: y - 4= 3(x - ( - 1))$

$\tt \: y - 4 = 3(x + 1)$

$\tt \: y - 4 = 3x + 3$

$\tt \: y = 3x + 3 + 4$

$\tt \: y = 3x + 7$

<em>Thus, The correct choice is option C!!~</em>

An unbiased coin is tossed 15 times. In how many ways can the coin land tails either exactly 8 times orexactly 5 times?

Kitty [74]

Answer:

Probability to get tails exactly 8 times or exactly 5 times is 0.29

Step-by-step explanation:

No of ways the coins lands tails exactly 8 times

P(8) = 15C8 × $0.5^{8}$ × $0.5^{15-8}$

No of ways the coin lands tails exactly 5 times

P(5) = 15C5 × $0.5^{5}$ × $0.5^{15-5}$

Probability to get tails exactly 8 times or 5 times

P(8)+P(5) = 15C8 × $0.5^{15}$ + 15C5 × $0.5^{15}$

P = $0.5^{15}$ ( 15C8 + 15C5 )

P = $0.5^{15}$ ( ( $\frac{15!}{8!(15-8)!}$ ) + ( $\frac{15!}{5!(15-5)!}$ ) )

P = $0.5^{15}$ ( 6435 + 3003 )

P = $0.5^{15}$ ( 9438)

P = $0.5^{14}$ ( 4719)

P = $\frac{4719}{16384}$

P = 0.29

Find dy/dx of y = <img src="https://tex.z-dn.net/?f=log_%7B2%7D" id="TexFormula1" title="log_{2}" alt="log_{2}" align="absmiddle

NikAS [45]

Step-by-step explanation:

$y = log_2 x^2 \\ \therefore y = \frac{log x^2}{log2}\\ (By\:change\:of\:base\:law) \\ \\ \therefore y = \frac{2log x}{log2}\\\\ differentiating \: both \: side \: w \: r \: t \: x. \\ \\ \frac{dy}{dx} = \frac{2}{log2} \bigg(\frac{d}{dx} log x \bigg) \\ \\ \therefore \frac{dy}{dx} = \frac{2}{log2} \bigg( \frac{1} {x} \times \frac{d}{dx} x \bigg) \\ \\ \therefore \frac{dy}{dx} = \frac{2}{log2} \bigg(\frac{1}{x} \times 1\bigg) \\ \\ \huge \red{ \boxed{\therefore \frac{dy}{dx} = \frac{2}{xlog2}}}$

If function f is the parent exponential function , what is the equation of transformed function g in terms of function f?

julia-pushkina [17]

Answer:

This problem is acually really simple.

Step-by-step explanation:

all you have to do is replace the a with a 3. SO It would look like this:

g(x)=3f(x)

hope this helps :)
