Answer:

Step-by-step explanation:

The angle at the centre of a circle is twice the angle at the circumference for angles subtended by the same arc.

∠DAR and ∠DBR are both subtended by the arc RD, hence

∠DAR = 2∠DBR = 2 × 34° = 68°

Answer:

Step-by-step explanation:

There is theorem in this chapter which explains the answer

According to the theorem ,

/_rbd = 2 /_ rad

Therefore , rbd = 34 ° .

Hence , rad = 2x 34

Therefore , rad = 68°

4 x ((-4)= (-2) - (-3) + (-6))

sergij07 [2.7K]

Answer:

x=5/16

Step-by-step explanation:

Let's solve your equation step-by-step.

4x(−4)=−2−(−3)−6

Step 1: Simplify both sides of the equation.

4x(−4)=−2−(−3)−6

−16x=−2+3+−6

−16x=(−2+3+−6)(Combine Like Terms)

−16x=−5

Step 2: Divide both sides by -16.

−16x

−16

=−5/−16

x=5/16

distribution has a mean if 18 standard deviation of 4 a value of 24 is how many standard deviations away from the mean

liraira [26]

A value of 24 is 2.5 standard deviations away from the mean

<h3>'How to determine the number of standard deviations away from the mean?</h3>

The given parameters about the distribution are:

Mean = 18

Standard deviation = 4

Value = 24

Let the number of standard deviations away from the mean be x.

The value of x is calculated using

Mean + Standard deviation * x = Value

Substitute the known values in the above equation

18 + 4 * x = 24

Subtract 18 from both sides of the equation

4 * x = 6

Divide both sides of the equation by 4

x = 1.5

Hence, a value of 24 is 2.5 standard deviations away from the mean

So, the complete parameters about the distribution are:

Mean = 18

Standard deviation = 4

Value = 24

24 is 2.5 standard deviations away from the mean

Solve: 1 × -23 = Question 9 options: -1 1 23 -23

Nonamiya [84]

Answer:

-23

Step-by-step explanation:

1 × -23

1. When multiply a positive number by a negative number, the answer will always be negative.

2. When we multiply any number by 1, that number will stay the same.

$1 * -23$
$-23$

Therefore, the answer is -23!

Find the distance between the points.<br> (0,4) and (-3,4)<br> The distance is

Inessa [10]

<h3>Answer: 3 units</h3>

=============================================================

Explanation:

The y coordinates are identical, so we just need to focus on the x coordinates.

Going from 0 to -3 is a distance of 3 units. Drawing out a number line might help.

Or we could apply subtraction and absolute value

|x1-x2| = |0-(-3)| = |0+3| = |3| = 3

which is the same as

|x2-x1| = |-3-0| = |-3| = 3

The absolute value is to ensure the result is never negative. Distance is never negative.

Side note: if the y coordinates weren't the same, then we'd have to use either the pythagorean theorem or the distance formula.
