Step-by-step explanation:
The y intercept is -7, the slope is 4
y=mx+b
m=slope b=y intercept
Answer:
y = 4x - 7
Step-by-step explanation:

A baseball rolls off a 1.20 m high desk and strikes the floor 0.50m away from the base of the desk. how fast was the ball rolling?
Answer:
1.01 m/s
Step-by-step explanation:
a = g = Acceleration due to gravity = [tex]9.81\ \text{m/s}^2[/tex]
t = Time
[tex]s_y[/tex] = Displacement in y direction = 1.2 m
[tex]s_x[/tex] = Displacement in x direction = 0.5 m
[tex]v_x[/tex] = Velocity in x direction
Displacement in y direction is given by
[tex]s_y=u_yt+\dfrac{1}{2}at^2\\\Rightarrow t=\sqrt{\dfrac{2s_y}{a}}\\\Rightarrow t=\sqrt{\dfrac{2\times 1.2}{9.81}\\\Rightarrow t=0.4946\ \text{s}[/tex]
[tex]s_x=v_xt\\\Rightarrow v_x=\dfrac{s_x}{t}\\\Rightarrow v_x=\dfrac{0.5}{0.4946}\\\Rightarrow v_x=1.01\ \text{m/s}[/tex]
The ball was rolling with a speed of 1.01 m/s.

The time spent waiting in the line is approximately normally distributed. The mean waiting time is 55 minutes and the standard deviation of the waiting time is 33 minutes. Find the probability that a person will wait for more than 88 minutes. Round your answer to four decimal places.
Answer:
Zero.
Step-by-step explanation:
The variable here is t where t is = time spent waiting in the line
The values for this variable and in this study, are normally distributed.
The mean waiting time = 55 minutes
The standard deviation = 33 minutes
What is the probability that t is greater than 88 minutes?
Now, the confidence interval about the mean for this study is:
[55-33], [55+33] = [22, 88]
Therefore, all values of t fall within this lower and upper limit or interval.
If that is the case, and recalling also that the distribution of values is normal, then it is impossible for t to be greater than 88 minutes.
Hence, P[t>88] = 0
To 4 decimal places, that would be 0.0000

The triangles are similar, and the angle bisectors are drawn from corresponding angles. what is the value of x?
Answer:
C. 6
Step-by-step explanation:
Given that both ∆s are similar, the ratio of their corresponding sides as well as the ratio of their angle bisectors would be the same.

Prob ( 2nd Red 'given' 1st Blue ) = 0.8 = 4/5
Step-by-step explanation:
Prob ( A I B ) = Prob (A ⋂ B) / P (B)
Prob ( 2nd Red 'given' 1st Blue ) = P ( 2nd Red & 1st Blue ) / P ( 1st blue)
P ( 1st blue & 2nd red ) = 32/128 , P ( 1st blue ) = 5/16
So, P ( 2nd Red I 1st Blue ) = ( 32 / 128 ) / ( 5/16 )
= 0.8 = 4/5
Answer:
4/5

An undergraduate class has 24 biology majors and 17 chemistry majors. Eight students must be chosen at random to represent an event organizing committee. What is the probability of choosing exactly two chemistry majors
Answer: 0.19158
Step-by-step explanation:
Given: An undergraduate class has 24 biology majors and 17 chemistry majors.
Total students needs to be selected = 8
Number of ways to select 8 students out of 41= [tex]^{41}C_8[/tex]
Number of ways to select exactly two chemistry majors (i.e. rest 6 will be biology majors) = [tex]^{24}C_6\times ^{17}C_2[/tex]
Required probability = [tex]\dfrac{^{24}C_6\times ^{17}C_2}{^{41}C_8}[/tex]
[tex]=\dfrac{\dfrac{24!}{6!(24-6)!}\times\dfrac{17!}{2!(17-2)!}}{\dfrac{41!}{8!(41-8)!}}\\\\=\dfrac{134596\times136}{95548245}\\\\= 0.19158[/tex]
The probability of choosing exactly two chemistry majors = 0.19158
