6 0

Answer:

Step-by-step explanation:

Sum of all angles of triangle = 180°

6p + 6p + 3 p = 180

15p = 180

p = 180/15

p = 12

Angles are:

6p = 6*12 = 72°

3p = 3*12 = 36°

Angles are: 72°, 72° , 36°

Another fair dice is rolled 300 times. How many times would you expect it to land with a multiple of three on top? I need help t
ira [324]

Answer:

100 times

Step-by-step explanation:

multiples of 3 on a number cube are 3 and 6

probability of rolling a '3' or '6' is 1/6 + 1/6 = 2/6 or 1/3

1/3 x 300 = 100

SAT scores are distributed with a mean of 1,500 and a standard deviation of 300. You are interested in estimating the average SA
kotegsom [21]

Answer:

I should use at least 304 students

Step-by-step explanation:

Margin error (E) = t × sd/√n

E = 40

sd = 300

confidence level (C) = 98% = 0.98

significance level = 1 - C = 1 - 0.98 = 0.02 = 2%

t-value corresponding to 2% significance level and infinity degree of freedom is 2.326

n = (t×sd/E)^2 = (2.326×300/40)^2 = 17.445^2 = 304 (to the nearest integer)

PLS HELP ME AND SHOW WORK.
Alex17521 [72]

Answer:

4 = (x  + 7 {)}^{2}  + (y  -  3 {)}^{2}

Step-by-step explanation:

equation of a circle

{r}^{2}  = (x -  {h} )^{2}  + (y -  {k)}^{2}

we know the center is (-7, 3)

the radius is 2

we replace (h,k) with the center coordinates

and input the radius

{2}^{2}  = (x -( - 7)) ^{2}  + (y  -  3)^{2}

simplify to this:

4 = (x  + 7 {)}^{2}  + (y  -  3 {)}^{2}
