Answer:

∠ SPQ = 75°

Step-by-step explanation:

The sum of the 4 angles in a quadrilateral = 360°

Subtract the sum of the 3 angles from 360 for ∠ SPQ

∠ SPQ = 360° - (90 + 74 + 121)° = 360° - 285° = 75°

Step-by-step explanation:

sum of all angles of quadrilateral=360°

SRQ+PQR+RSP+SPQ=360°

90°+74°+121°+SPQ=360°

285+SPQ=360°

SPQ=360-285

SPQ=75

How do you solve x in this equation ➡️ 2x-14=10 // And to simplify it for the answer??!!!
DENIUS [597]
So we start by getting x on one side of the equals sign

2x-14=10
   +14 +14

2x=24

divide them both by 2 to get x by itself

x=12

an employee is selected from a staff of 10 to super- vise a certain project by selecting a tag at random from a box containing 1
USPshnik [31]

Probability that the number drawn is less than 4 is given by 0.3

<h3>What is probability?</h3>

The likelihood of an event happening is gauged by probability.

The probability might be between 0 and 1, where 0 denotes an impossibility and 1 denotes a certainty.

The overall chance of every event in a sample space is 1.

Let random variable X represent the number of the drawn tag.

Since the simple space consists of 10 equally likely events

S = {1,2,3,4,5,6,7,8,9,10}

The formula for probability distribution is given by:

f(x) = { (1/10) for x = 1,2....10,    else 0 elsewhere

since, each number can equally likely occur, therefore

P(x) = 1/10 = 0.1

Probability that the number drawn is less than 4 is given by:

P(x<4) = P(1) + P(2) + P(3)

           = 0.1 + 0.1 + 0.1

           = 0.3
