Answer: 90°

Step-by-step explanation:

A measure of central tendency is a single value that attempts to describe a set of data by identifying the central position within that set of data. ...

Find the value of unknown angles.<br>Х<br>50

Gennadij [26K]

Answer:

$x = 70^o$

Step-by-step explanation:

Given

See attachment for triangle

Required

Find x

To solve for x, we make use of:

$x + 50^o + 60^o = 180^o$ --- angles in a triangle

$x + 110^o = 180^o$

Collect like terms

$x = 180^o-110^o$

$x = 70^o$

Solve two step equations: <br><br> 3y +1/5 = 2/5

asambeis [7]

Answer:

y = 1/15

Step-by-step explanation:

3y + 1/5 = 2/5

Subtract 1/5 from each side

3y +1/5 -1/5 = 2/5 -1/5

3y = 1/5

Multiply by 1/3

3y *1/3 = 1/5 *1/3

y = 1/15

The chance of having either a boy or a girl is 50%. What is the probability of the Smiths having two girls?

PilotLPTM [1.2K]

Based on the fact that the chance of having a boy or a girl is 50%, the probability of the Smiths having two girls is 25%.

<h3>What is the probability of having two girls?</h3>

When you are faced with two independent events happening one after the other, the way to find their probability is:

= Probability of first event x Probability of second event

The probability of the Smiths getting two girls is therefore:

= 50% x 50%

= 25%
