A bag contains red and blue marbles, such that the probability of drawing a blue marble is 3/8. An experiment consists of drawin

Verizon [17]

Answer:

5/8

Step-by-step explanation:

Find P(x = 3 blues for the 2 draws)

two draws

Binomial probability.

we know p = 3/8 for blue, else q = 1 - q = 1 - (3/8)

X = # of blue marbles left in the bag.

apparently it looks like there are 8 marbles in the bag, 3 are blue, 5 are red

X = 3 , means the draw was a red 5/8 for the first draw

the 2nd draw can be a blue or a red so, probability is 1

P(X = 3) = (5/8) * 1 = 5/8

The ratio of the perimeters of two similar triangles is 4:7. What is the area of each of these triangles if the sum of their are

Mashcka [7]

Answer:

The area of triangles are 16 cm^2 and 49 cm^2

Step-by-step explanation:

we know that

If two figures are similar, the ratio of its perimeters is equal to the scale factor and the ratio of its areas is equal to the scale factor squared

Let

z ----> the scale factor

x ----> the area of the smaller triangle in square centimeters

y ----> the area of the larger triangle in square centimeters

we know that

$z=\frac{4}{7}$

$\frac{x}{y}=z^2$

$\frac{x}{y}=(\frac{4}{7})^2$

$\frac{x}{y}=\frac{16}{49}$

$x=\frac{16}{49}y$ -----> equation A

$x+y=65$ ----> equation B

solve the system by substitution

substitute equation A in equation B

$\frac{16}{49}y+y=65$

solve for y

$\frac{65}{49}y=65$

$y=49\ cm^2$

Find the value of x

$x=\frac{16}{49}(49)$

$x=16\ cm^2$

therefore

The area of triangles are 16 cm^2 and 49 cm^2

The graph of g(x) goes through the point (-4, 1) and is parallel to h(x) = 5x - 2 points

vesna_86 [32]

Answer:

$g(x)=5x+21$

Step-by-step explanation:

The slope of g(x) is 5 because the slope of h(x) is 5 and g is parallel to h.

In point-slope form:

$g(x)-1=5(x+4)$

Rearranging for slope intercept form:

$g(x)-1=5x+20\\g(x)=5x+21$
