Let's see, if she has made 65% of n throws so far, then she needs to throw x more in a row to get 68%.
so you would do:
.65n+x=.68(n+x)
.03n=.32x
x=3/32 n

To make 70% she has completed 7 out of 10 shots. for her to get 75% she would need 3 out of 4 each time.

Given the domain {-4, 0, 5}, what is the range for the relation 12x 6y = 24? a. {2, 4, 9} b. {-4, 4, 14} c. {12, 4, -6} d. {-12,
xz_007 [3.2K]

The domain of the function 12x + 6y = 24 exists {-4, 0, 5}, then the range of the function exists {12, 4, -6}.

<h3>How to determine the range of a function?</h3>

Given: 12x + 6y = 24

Here x stands for the input and y stands for the output

Replacing y with f(x)

12x + 6f(x) = 24

6f(x) = 24 - 12x

f(x) = (24 - 12x)/6

Domain = {-4, 0, 5}

Put the elements of the domain, one by one, to estimate the range

f(-4) = (24 - 12((-4))/6

= (72)/6 = 12

f(0) = (24 - 12(0)/6

= (24)/6 = 4

f(5) = (24 - 12(5)/6

= (-36)/6 = -6

The range exists {12, 4, -6}

Therefore, the correct answer is option c. {12, 4, -6}.

.006 + .0002 in scientific notation
Vilka [71]
6.2 x 10^-3 Because when you add them together you get .0062 so you don't want anymore than one number to the left of decimal when in scientific notation therefore its 6.2 so you wanna move the decimal three spaces to the left to get .0062 therefore its 6.2x10^-3

Help plz<br>Find the measurement of the angles of a triangle if they are in the ratio 5:4:3 ​
Lerok [7]

Answer:

<u>See below:</u>

Step-by-step explanation:

Let the angles be 5x , 4x , 3x.[Since the angles are in ratio 5:4:3 ] respectively.

We know that sum of all angles of a triangle is 180°.

So,

5x + 4x + 3x = 180   {}^{ \circ}

Now Find the value of x of this equation.

\sf  \implies \: 5x + 4x + 3x = 180 {}^{ \circ}

\sf  \implies12x = 180 {}^{ \circ}

\sf  \implies \: x =  \cfrac{180 { {}^{ \circ} }}{12}

\sf  \implies \: x =  \cfrac{ \cancel{180 {}^{ \circ}} }{  \cancel{12}}

\sf  \implies \: x = 15 {}^{ \circ}

Now,

Multiply each ratio given by 15 which is the value of x we got.

That is;

\therefore \sf\implies \: First \: Angle = 5 \times 15  {}^{ \circ}  = \boxed{75 {}^{ \circ}}

\sf \sf  \implies \: Second\: Angle = 4\times 15  {}^{ \circ}  = \boxed{60 {}^  \circ}

\sf  \implies \: Third\: Angle = 3 \times 15 =  \boxed{ {45}^ \circ}

Hence,the measurements of the angles of the triangle would be 75°[First Angle],60°[Second angle],and 45° [Third Angle].

I hope this helps!
