Answer:
x=12
Step-by-step explanation:
Every triangle has interior degrees that all together add up to 180. We already know we have 50 degrees and 75 degrees, so we can subtract that to see how much we have left to work with. If we do that, we get 55 degrees left. Now, we have to set up a two step equation to find x:
5x-5=55
The first thing to do is to add 5 to both sides to get rid of -5:
5x-5=55
+5 +5
__ __
0 60
So now, it's 5x=60
Now, we have to isolate x. To do this, we have to divide both sides by 5. If you do this, you get:
x=12
Hope this helped!
Answer: b) x = 12
Step-by-step explanation:
The sum of a triangle's angles add up to 180°. We will add together all the angles, set them equal to 180°, and then solve.
Given:
(50°) + (75°) + (5x - 5°) = 180°
Combine similar terms:
120° + 5x = 180°
Subtract 120° from both sides of the equation:
5x = 60°
Divide both sides of the equation by 5:
x = 12
Your answer is;
b) x = 12

if x/5 + 6 = -14, then x =
Answer:
The answer is (-100).
Step-by-step explanation:
Given;x/5 + 6 = -14To Find;The value of xNow,
x/5 + 6 = -14
Cross multiplication
x + 5 × 6 ÷ 5 = -14
x + 30/5 = -14
Multiply 5 both sides we get,
x + 30/5 × 5 = -14 × 5
x + 30 = -70
x + 30 – 30 = -70 – 30
x = -100
Thus, The value of x is (-100).
Answer:
[tex]\huge\boxed{\sf x = -100}[/tex]
Step-by-step explanation:
Given Equation:
x/5 + 6 = -14
Subtract 6 to both sides
x/5 = -14 - 6
x/5 = -20
Multiply 5 to both sides
x = -20 × 5
x = -100

n physics, we can find the amount of force needed to push or pull an object by multiplying the object’s mass by the object’s acceleration. The units of force are called Newtons.
force = mass × acceleration
F = ma
Find the amount of force it takes to push Jeff’s race car if the mass of the race car is 750 kg and the acceleration is 2.5 StartFraction m Over s squared EndFraction
The amount of force needed to push Jeff’s race car is
Newtons.
The amount of force it takes to push Jeff’s race car will be 1875 Newtons.
What is force?Force is explained as the multiplication of mass and acceleration. Its unit is N. It is the external agent which helps to change the shape and size of an object.
The formula of force will be
F = ma
Where m is the mass of the body and a is the acceleration of the body.
Then the amount of force it takes to push Jeff’s race car if the mass of the race car is 750 kg and the acceleration is 2.5 meters per square second.
Then we have
F = 750 x 2.5
F = 1875 Newton

Assume that the salaries of computer programmers are normally distributed, with a mean of $66,000 and a standard deviation of $14,000.
If four programmers are selected at random, find the probability that they have a mean salary between $40,000 and $50,000.
a) 0.52
b) 0.09
c) 0.26
d) 0.01
The probability that they have a mean salary between $40,000 and $50,000 is 0.01.
What is Z- score test?A z-test is a statistical test to determine whether two population means are different when the variances are known and the sample size is large.
The z-score for 40,000 is
= (40,000 - 66000) / (14,000 / √4)
= -26000/7000
= -3.714, P- value is 0.000102
The z-score for 50,000
= (50,000 - 66,000) / (14,000 / √4)
=-2.285, P- value is 0.0111564
P(40,000 < x < 50,000) = P( -3.714< z < -2.285)
So,
= P(50,000)-P(40,000)
= 0.0111564-0.000102
=0.011
Hence, the probability that they have a mean salary between $40,000 and $50,000 is 0.01.

a family has three children child a child be and child C child a is younger than child see child be is not older than child a from youngest to oldest how are the children ordered by age
Answer:
I'd say the order from youngest to oldest, would be B A C.
Step-by-step explanation:
My reason is that, A is younger than C or in other words C is older than A. Also B is NOT older than A, so therefore B must be younger than A.
So from youngest to oldest, B is younger than A, A is younger than C, and that means C is the absolute oldest out of the three children.

PLEASSEEEE HELP ASAP , WHAT IS THE SHAPE OF THE BASE AND SURFACE AREA?
Answer:
Total surface area : 733
The shape of the base is a rectangle with sides 11 in. and 12 in.
Step-by-step explanation:
The shape of the base is a rectangle with sides 11 in. and 12 in.
The surface area is the sum of the areas of the 5 sides.
Area of the base = 11*12 = 132
Area of the two triangles = (11*16)/2 = 88
Area of the back rectangle = 192
The theorem of Pitagora to find the oblique side: square root of (11*11 + 16*16)= 19.42 in.
So the area of the oblique face: 19.42* 12 = 233 (almost :) )
So total surface area: 132 + 88*2+192+233= 733 square in

45, 52, 56, 61, 69
Step-by-step explanation:
Given the five summary of a data set:
45 - min
52 - Q1
56 - Median
61 - Q3
69- Max
Thus, any number less than Q1-(1.5×IQR)
, or any number that is greater than
Q3+ (1.5 × IQR) would be considered an outlier.
The IQR of the data set = Q3 - Q1 = 61-
52 = 9
Thus,
Q1- (1.5 × IQR) =52- (1.5* 9) = 52 - 13.5=38.5
Therefore, an observation is considered
an outlier if it is below: 38.5
Q3 + (1.5 * 1QR) = 61 + (1.5 * 9) =61+13.5 =74.5
Therefore, an observation is considered
an outlier if it is above: 74.5
