Find the value of X. Show work!!!

Mathematics
1 answer:
barxatty [35]2 years ago
6 0

Answer:

x = -10

Angle 2 = 49°

Angle 3 = 49°

Step-by-step explanation:

In the given figure, it's an isosceles triangle

so, angle 2 = angle 3

( since their opposite sides are equal )

now,

in the given triangle,

=》Angle 2 + Angle 3 + 82° = 180°

( sum of all interior angles of the triangle = 180° )

=》Angle 2 + Angle 3 = 180° - 82

=》Angle 2 + Angle 3 = 98°

=》2 × Angle 2 = 98°

( since, angle 2 = angle 3 )

=》Angle 2 = 98° / 2

=》Angle 2 = 49°

so, Angle 2 = 49° = Angle 3

now,

Angle 2 = x + 59

=》49 = x + 59

=》x = 49 - 59

=》x = -10

A certain brand of automobile tire has a mean life span of 35,000 miles, with a standard deviation of 2250 miles. Assume the lif
yawa3891 [41]

Answer:

Step-by-step explanation:

From the information given:

mean life span of a brand of automobile = 35,000

standard deviation of a brand of automobile = 2250 miles.

the z-score that corresponds to each life span are as follows.

the standard z- score formula is:

z = \dfrac{x - \mu}{\sigma}

For x = 34000

z = \dfrac{34000 - 35000}{2250}

z = \dfrac{-1000}{2250}

z = −0.4444

For x = 37000

z = \dfrac{37000 - 35000}{2250}

z = \dfrac{2000}{2250}

z = 0.8889

For x = 3000

z = \dfrac{30000 - 35000}{2250}

z = \dfrac{-5000}{2250}

z = -2.222

From the above z- score that corresponds to their life span; it is glaring  that the tire with the life span 30,000 miles has an unusually short life span.

For x = 30,500

z = \dfrac{30500 - 35000}{2250}

z = \dfrac{-4500}{2250}

z = -2

P(z) = P(-2)

Using excel function (=NORMDIST -2)

P(z) = 0.022750132

P(z) = 2.28th percentile

For x =  37250

z = \dfrac{37250 - 35000}{2250}

z = \dfrac{2250}{2250}

z = 1

Using excel function (=NORMDIST 1)

P(z) = 0.841344746

P(z) = 84.14th percentile

For x = 35000

z = \dfrac{35000- 35000}{2250}

z = \dfrac{0}{2250}

z = 0

Using excel function (=NORMDIST 0)

P(z) = 0.5

P(z) = 50th percentile

Write 375,000 in scientific notation
allsm [11]
We need to move the decimal so that there is only one whole number.

375,000.

To do that, we move to the left 5 spaces

3.75000

Now since we moved 5 spaces to the left it would be 3.75 * 10^5

A clydesdale drinks about 120 gallons of water every 4 days at this rate about how many gallons of water does clydesdale drink i
nignag [31]
In 28 days, a clysedale would drink about 840 gallons of water. Due to the fact that clysedale drinks 120 gallons of water every 4 days, you would first find the number of gallons that it can drink in one day, so 120 divided by 4 equals 30, so the horse drinks 30 gallons of water a day. To find out how many many gallons the clysdale would drink in 28 days, you need to multiply 30 by 28, to find the answer of 840.
