Answer:
-10
Step-by-step explanation:
Let x = number
10 less than a number is the same number doubled
x-10 = 2x
Subtract x from each side
x-10-x = 2x-x
-10 = x
The number is -10
The value of the probability P(3≤x<7) is 1
<h3>How to evaluate the probability expression?</h3>
The expression is given as: P(3≤x<7)
This is calculated using:
P(3 ≤ x < 7) = P(3) + P(4) + P(5) + P(6)
Using the figure of the probability density function (see attachment), we have:
P(3 ≤ x < 7) = 0.30 + 0.30 + 0.20 + 0.20
Evaluate
P(3 ≤ x < 7) = 1
Hence, the value of the expression is 1

You do the same as whole numbers! Make sure the denominators are the same, add them all up, and then divide by the number of fractions there are!

Answer:
Step-by-step explanation:
<h3>Question 1</h3>
<u>Prove that The two triangles are congruent</u>
- ∠ABD ≅ ∠BDC - given
- BD ≅ DB - reflexive property
- ∠ADB ≅ ∠CBD - given
- ΔABD ≅ ΔCDB - ASA postulate
<u>Find the measure of angle C</u>
- ∠A ≅ ∠C - Corresponding parts of congruent triangles
- m∠C = m∠A = 180° - (62° + 70°) = 180° - 132° = 48°
<h3>Question 2</h3>
<u>Given </u>
Opposite angles are corresponding to the sides.
Therefore the angles opposite to congruent sides are also congruent:
