Answer:

$y=\frac{3}{4} x$

Step-by-step explanation:

The line passes the origin(0,0) and point (4,3). Using rise/run we can tell that the slope is 4/3
and using y=mx+b where m represents the slope we can tell that the final equations is $y=\frac{3}{4} x$

Answer: Expected value would be $\dfrac{17}{5}$

Step-by-step explanation:

Since we have given that

Number of multiple choice question = 4

Number of true false questions = 2

Number of points for each multiple choice question = 3

Number of points for each true false question = 1

Number of choices in multiple choice = 5

Probability of getting correct answer in multiple choice question = $\dfrac{1}{5}$

Probability of getting correct answer in true false question = $\dfrac{1}{2}$

Expected value of the student's score on the test would be

$E(x)=\sum xp(x)\\\\E(x)=4\times 3\times \dfrac{1}{5}+2\times 1\times \dfrac{1}{2}\\\\E(x)=\dfrac{12}{5}+1\\\\E(x)=\dfrac{12+5}{5}=\dfrac{17}{5}$

Hence, expected value would be $\dfrac{17}{5}$

I need help solving this right triangle, please!

Vesna [10]

We know the opposite and adjacent sides of angle B, so we can use the inverse tangent to solve for its value.
tan(B)^-1 = 3/4
B = 64.4 degrees

lutik1710 [3]

The whole string was 2.4m. If you take 1/3 of 1/2x, you are just taking 1/6x. You know that what remains is 2m, and that it's the remaining 5/6. So you divide 2 by 5 and multiply that by six to get 2.4.

A varsity boy's basketball team has ratio of seniors to juniors that is 7:4. If the team is made up of only juniors and seniors,

DENIUS [597]

Answer:

The ratio of seniors to the total team members is 7: 11

Step-by-step explanation:

Let us solve the question

∵ A varsity boy's basketball team has a ratio of seniors to juniors that is 7: 4

∴ seniors: juniors = 7: 4

→ That means seniors have 7 parts and juniors has 4 parts

∴ The seniors' members = 7 parts

∴ The juniors' members = 4 parts

→ Add them to find the total parts of the team

∴ The team's members = 7 + 4 = 11 parts

→ To find the ratio of the seniors' members to the total team's member

divide their parts

∵ The seniors ÷ The total = $\frac{7}{11}$

∵ The seniors' member : The team's members = 7: 11

∴ The ratio of seniors to the total team members is 7: 11
