X=7

Explanation:

A triangle equals 180°, and they gave us one length already, and it says the one arm of the triangle is equal to the other so we know that the third angle is going to be the same as the second angle.

180=90+(6x+3)+(6x+3)
Combine like terms
180=96+12x
Subtract 96 from both sides
84=12x
Divide 12 by both sides
7=x

Now check it,

90+(6*7+3)+(6*7+3)
90+(45)+(45) =180

Suppose you have gone bowling with an excellent player who bowls a strike (i.e. when they hit all of the pins) 73% of the time.

Elina [12.6K]

Answer:

The probability of bowling 3 consecutive strikes is 0.3890.

Explanation:

On any given turn, this player has a 73% chance of bowling a strike. Hence:

Probability of bowling a strike = P(S) = 73% = 0.73

We need to find the probability of this player bowling 3 consecutive strikes. This is computed as follows:

Probability of bowling 3 consecutive strikes

= Probability of bowling first strike x Probability of bowling second strike x Probability of bowling third strike

= P(S) x P(S) x P(S)

= 0.73 x 0.73 x 0.73

= 0.3890

Why does.the equation y=3x+5 NOT represent a proportional relationship

sergiy2304 [10]

Answer:

The equation not represent a proportional relationship because the line don't passes through the origin

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $k=\frac{y}{x}$ or $y=kx$

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

In this problem we have

$y=3x+5$

This is the equation of the line in slope intercept form

where

the slope is m=5

the y-intercept is b=5

Remember that in a proportional relationship the value of b must be equal to zero (because the line passes through the origin)

therefore

The equation not represent a proportional relationship because the line don't passes through the origin
