4 0

Answer:

Step-by-step explanation:

The mean or average is calculated by summing each element and then dividing by the number of elements.

We have: 35, 30, 45, 65, 44, and 21.

There are six elements in total.

We find the sum by adding. Hence:

$35+30+45+65+44+21=240$

We will now divide by 6, the number of elements:

$240/6=40$

Therefore, the mean runs scored by the batsman is 40.

Hence, our answer is D.

The length of AC is 16 km.

Solution:

Given data:

AB = c = 14 km, ∠A = 30° and ∠B = 89°

AC = b = ?

Let us first find angle C:

Sum of all angles in a triangle = 180°

m∠A+ m∠B + m∠C = 180°

30° + 89° + m∠C = 180°

119° + m∠C = 180°

Subtract 119° from both sides, we get

m∠C = 61°

To find the length of AC:

Using sine formula:

$$\frac{b}{\sin B } =\frac{c}{\sin C}$

Substitute the given values in the formula.

$$\frac{b}{\sin 89^\circ } =\frac{14}{\sin 61^\circ }$

Multiply by sin 89° on both sides.

$$\sin 89^\circ \times \frac{b}{\sin 89^\circ } =\frac{14}{\sin 61^\circ } \times \sin 89^\circ$

$$b=\frac{14}{0.8746 } \times0.9998$

$b=16$

The length of AC is 16 km.

i need help hurry plz? what the meaning of y and x intercept in the problem and tell me the answer of the last question

Nezavi [6.7K]

Answer:

For the first picture, the y-intercept is the height the pebble was dropped from. The x-intercept is the amount of seconds it took for the pebble to hit the ground.

For the second picture, the y-intercept is the height of the soccer ball (ground level). The x-intercept is the amount of seconds it took for the soccer ball to hit the ground.

A city planner is comparing traffic patterns at two different intersections. He randomly selects 12 times between 6 pm and 10 pm

kicyunya [14]

Let the mean number of cars passing through intersection 1 be μ1 and that of intersection 2 be μ2. Then the appropriate test of the city planner's hypothesis is
H0: μ1 - μ2 = 0
H1: μ1 - μ2 ≠ 0

What is the distance between (-6. 2) and (8.10) on a coordinate grid?

nalin [4]

Answer:

The distance between 2 points is 16.1 units.

Step-by-step explanation:

You have to apply distance formula using coordinates,

$distance = \sqrt{ {(x2 - x1)}^{2} + {(y2 - y1)}^{2} }$
