Answer:
5 is D
6 is C
Step-by-step explanation:
Define:
Equilateral - All sides and angles are congruent
Isosceles: Two congruent sides and two congruent angles
Scalene: No congruent sides or angles
Right triangle: A triangle with a right angle ( note that a right angle has a measure of 90 degrees )
obtuse triangle: A triangle with an obtuse angle ( obtuse angles have a measure of more than 90 degrees. )
Acute triangle : A triangle with an acute angle ( an acute angle has a measure of less than 90 degrees )
Answer:
the triangle shown in # 5 has a right angle and 2 congruent sides and angles
Therefore the triangle in #5 is a right isosceles
The triangle shown in #6 has an angle with a measure that is more than 90 degrees and have no congruent sides or angles therefore the triangle in #6 is an obtuse scalene.
Answer:
Subtract 6 from both sides of this equation.

Answer:
Step-by-step explanation:
In the Point-Slope Formula [<em>y</em> - <em>y</em>₁ = <em>m</em>(<em>x</em> - <em>x</em>₁)], all the negative symbols give the OPPOSITE terms of what they really are, so be EXTREMELY CAREFUL inserting the coordinates into the formula with their CORRECT SIGNS.

Answer: P(200 ≤ x ≤ 275) = 0.4332
Step-by-step explanation:
Since the credit ratings are normally distributed, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = credit ratings for applicants
µ = mean
σ = standard deviation
From the information given,
µ = 200
σ = 50
The probability of a rating that is between 200 and 275 is expressed as
P(200 ≤ x ≤ 275)
For x = 200,
z = (200 - 200)/50 = 0
Looking at the normal distribution table, the probability corresponding to the z score is 0.5
For x = 275,
z = (275 - 200)/50 = 1.5
Looking at the normal distribution table, the probability corresponding to the z score is 0.9332
Therefore,
P(200 ≤ x ≤ 275) = 0.9332 - 0.5 = 0.4332
Answer: D. 'An African elephant can reach a top speed of about 24 mph because 36 ÷ 3/2 = 24'
Step-by-step explanation:
This means the grizzly bear is 3/2 times faster than the elephant
it also means the african elephant's speed would be 2/3 that
therefore,
⇒ 24
So, the speed of an African elephant is 24 mph
