Find the point-slope equation of the line contains (-2,-3) and having slope m=4

Mathematics

vodomira [7]3 years ago
3 0

Answer:

y + 3 = 4 x (x + 2)

Step-by-step explanation:

point slope formula is y-y1 = m(x-x1)

slope intercept form is y = 4x + 5

                                       y=mx +b

                                           m=4

Answer:

It seems that problem might have an error.

population = 600 * e ^ (.02*t)  where e = 2.718281828459

So, at day 1 we have

day 1 population = 600 * 2.718281828459 ^(.02*1) = 32.62

day 2 population = 600 * 2.718281828459 ^(.02*2) = 88.67

We can see that the population doubles in less than one day  but the lowest of those multiple choices is 34.657 days

The table displays the frequency of scores for a calculus class on an exam. The mean of the exam scores is 3.5. Score 1 2 3 4 5
vladimir1956 [14]

Answer:

f=11

Mode=4

Median=4

Explanation:

We are given that

a.Mean of the exam score,\bar x=3.5

Score(x)   frequency   C.F

1                  1                 1

2                  3                4

3                  f                 15(4+f=4+11)

4                  13               28

5                   4               32

\sum f_i=1+3+f+13+4=21+f

\sum f_ix_i=1(1)+2(3)+3(f)+4(13)+5(4)=1+6+3f+52+20=79+3f

(\bar x)=\frac{\sum f_ix_i}{\sum f_i}

Using the formula

3.5=\frac{79+3f}{21+f}

73.5+3.5f=79+3f

3.5f-3f=79-73.5

0.5f=5.5

f=\frac{5.5}{0.5}=11

b.Mode:The number which is repeat most times .

4 repeat most times

Hence, mode of all exam scores=4

N=32

N is even

Median=\frac{(\frac{n}{2})^{th}+(\frac{n}{2}+1)^{th}}{2}

Median=\frac{16th+17th}{2}=\frac{4+4}{2}=\frac{8}{2}=4
