o-na [289]3 years ago
3 0

Answer: The probability that a value is less than 36.8 is 0.9993.

Step-by-step explanation:

Let X be the random variable that normally distributed.

Given: \mu=32,\sigma=1.5

The probability that a value is less than 36.8 = P(X

=P(\frac{X-\mu}{\sigma}[Using P-value calculator]

Therefore, The probability that a value is less than 36.8 is 0.9993.

Angle 1 and angle 2 are vertical angles. solve for x if angle 1 is (x-3) and angle 2 is 50 degrees.
Elza [17]
You set them equal to each other because vertical angles are congruent so,
(x-3)=50
x=53

Circle 1 is centered at (5,8) and has a radius of 8 cm. Circle 2 is centered at (1,-2) and has a radius of 4cm. The circles are
maria [59]
From the given information:
Circle 1:
Center (5,8)
radius= 8 cm 

Circle 2:
Center (1,-2)
radius= 4 cm

The above circle are similar because you can translate Circle 1 using the transformation rule (-4,-10) translation and dilate it using a scale factor of 4/8=1/2

Aiko is finding the sum (4 + 5i) + (–3 + 7i). She rewrites the sum as (–3 + 7)i + (4 + 5)i. Which statement explains the mathema
yan [13]
In this item, it can be seen that from an expression of,
                                  (4 + 5i) + (-3 + 7i)
Aiko transformed the equation by factoring out the i's from the expression and wrote it as,
                                   (4 + 5)i + (-3 + 7)i
Now this is wrong because i there is not a variable but a notation that 5 and 7 are imaginary numbers. In fact, she cannot factor out the i's because it is not present in both -3 and 4. The answer therefore to this item is the last sentence, "Aiko incorrectly used the distributive property by combining ..."
