Answer:

11 C

Step-by-step explanation:

To find the mean (average), you have to add all and divide by 2, so if you reverse this, you get (7 + X)/2  = 9 , 9 * 2 - 7 = 11

Answer:

If the mean was 7 for the first 4 days that means the sum of temperatures of the first 4 days was 7 * 4 = 28. Similarly, the sum of temperatures of the first 5 days was 9 * 5 = 45 so that means that the temp. on the 5th day was 45 - 28 = 17°C.

The measure of the angle R is m \angle R=69.4

Explanation:

It is given that the lengths of the triangle are PQ = 8 and QR = 3

To find the angle of R using the opposite and adjacent side, we shall use the tangent formula.

\tan \theta=\frac{o p p}{a d j}

where opp = 8 and adj = 3

Thus, substituting these values in the formula, we get,

\tan \theta=\frac{8}{3}

Multiplying both sides by tan^{-1}, we get,

\theta=tan^{-1} (\frac{8}{3})

Dividing, we get,

\theta=69.44

Rounding off to the nearest tenth, we have,

\theta=69.4

Thus, the measure of the angle R is m \angle R=69.4

Step-by-step explanation:

we start with the fractions, we have 3/4 and 1/4 which makes a whole, to make it easier i added that to 329 to get 330. Then i added 330 to 210 to get 540.

Indicate in standard form the equation of the line passing through the given points.
lorasvet [3.4K]

Answer:

y = 6

Step-by-step explanation:

Let the y-intercept form of the equation of the line is,

y = mx + b

Here, m = Slope of the line

b = y-intercept

Slope of the line passing through two points (x_1,y_1) and (x_2,y_2) is given by,

m = \frac{y_2-y_1}{x_2-x_1}

Slope of the passing through (0, 6) and (5, 6) will be,

m = \frac{6-6}{0-5}

m = 0

Equation of the line with m = 0 will be,

y = 0 + b

y = b

Since, line passes through (0, 6),

By substituting the values in the equation,

b = 6

Therefore, standard equation of the line passing through (0, 6) and (5, 6) will be,

y = 6
