The value x is x = 15
The three sides of the triangle are
x+10 = 25
2x-5 = 25
3x-15 = 30
==================================================
Work Shown:
The curved angle markers indicate those two angles are the same measure. The sides opposite those angles are the same length. So 2x-5 and x+10 are the same value
2x-5 = x+10
2x-x = 10+5
x = 15
Once we know x, we can find the length of each side
x+10 = 15+10 = 25
2x-5 = 2*15-5 = 30-5 = 25
This also helps confirm we have the right x value (since we got the same value for each expression)
3x-15 = 3*15-15 = 45-15 = 30
This is an isosceles triangle because exactly two sides are the same length.
Answer:
D
Step-by-step explanation:
<u>The question is about multiplication of matrices</u>
Given matrix A as [6 -12]
[4 8]
if 1/2x= A
then x=2A
A={6 -12}
{4 8}
x=twice A or A +A
<u>solving for 2A</u>
2A=(2×6 2×-12)
(2×4 2×8)
2A= (12 -24)
(8 16)
Answer:
the answer is c, science CANNOT answer all questions
Answer:
<u>Population : all the steaks Tessa can cook</u>
<u>Parameter : minimum internal temperature of 160 degrees Fahrenheit</u>
<u>Sample : two random thermometer readings</u>
<u>Statistic : minimum sample reading of 165 degrees Fahrenheit</u>
Step-by-step explanation:
Let's recall the definitions of these statistical concepts and match it with the information that were provided to us:
- Populations can be the complete set of all similar items that exist, in our case, all the steaks that Tessa can cook.
- Parameter is is a value that describes a characteristic of an entire population, such as the minimum temperature of the steaks Tessa is cooking in Fahrenheit degrees.
- Sample is a subset of the population, in our case, the two random readings of the thermometer Tessa did.
- Statistic is a characteristic of a sample, for our problem, it's the minimum reading of 165 degrees Fahrenheit.
