IM REALLY CONFUSED! Help!!!!!!! Please explain your answer, thank you!

ABOUT THIS FORMULA:

  • <u>Y2 - Y1</u>

        X2 - X1

FOR PROBLEM: (2, 1) & (0, -5)

  • Y2 is -5
  • Y1 is 1
  • X2 is 0
  • X1 is 2

ABOUT POINT SLOPE FORM:

  • y - Y1 = m(x - X1)
  • Y1 & X1 is a point
  • m represents the slope
  • This form allows you to identify the slope & the point on the line

ABOUT SLOPE INTERCEPT FORM:

  • y = mx + b
  • m represents the slope
  • b represents the y - intercept AKA the starting point

<u>Y2 - Y1</u>

X2 - X1

<u>-5 - 1</u>

0 - 2

<u>-6</u>

-2

SIMPLIFIED: -3 because both -6 & -2 can be divided by 2.

y - Y1 = m(x - X1)

y - -1 = -3(x - 2)

y + 1 = -3x + 6

   - 1           - 1

y = -3x - 5 --- SLOPE INTERCEPT FORM


I do not see y = -3x - 5 as one of your answer choices.... So, I am sorry if I am incorrect...

Answer:

6root 85 /85 is ans..

Step-by-step explanation:

given,

a=7 and b=6

as it is a Right angled triangle

h^2=p^2+b^2

h =   \sqrt{p {}^{2}  + b {}^{2} }

so,

\sqrt{6 {}^{2}  + 7 {}^{2} }

=

\sqrt{85}

now, sin thita=p/h

so sin thita=

6   \div  \sqrt{85}

=6   \sqrt{85} \div 85

ans...

hope its helpful....

In a​ survey, 13001300 adults in a certain country were asked how many hours they worked in the previous week. Based on the​ res
artcher [175]

Answer:

The correct option is (A).

Step-by-step explanation:

The (1 - α)% confidence interval for population parameter implies that there is a (1 - α) probability that the true value of the parameter is included in the interval.

Or, the (1 - α)% confidence interval for the parameter implies that there is (1 - α)% confidence or certainty that the true parameter value is contained in the interval.

The 95% confidence interval for mean number of hours worked was,

CI = (39.6 hours, 43.9 hours).

The 95% confidence interval for mean number of working hours, (39.6, 43.9) hours, implies that the true mean number of working hours for the adults of the country lies in this interval with probability 0.95.

So, there is a 95% confidence or chance that the true mean values lies in the interval (39.6, 43.9).

Thus, the correct option is (A).
