Answer:
5-7 x = 2
Step-by-step explanation:
a number times negative seven added to five equals two
"a number times negative seven added to five equals two" is represented by expression 5-7x=2
What is Expression?An expression is combination of variables, numbers and operators.
The given sentence is "a number times negative seven added to five equals two"
Here let us consider the unknown number to be x.
As in the sentence we have a number times negative seven.
Times in the sentence means product. So the number x is multiplied with -7. i.e is -7x
Now a number times negative seven added to five.
This means 5 is added to -7x
-7x+5
"a number times negative seven added to five equals two" means -7x+5 is equal to two
-7x+5=2
5-7x=2
Hence the "a number times negative seven added to five equals two" is represented by expression 5-7x=2

An object is moving at a speed of 7 feet per minute. Express this speed in meters per second.
Answer:
2.1 mpm
Explanation:
1ft = 0.3048 m
[tex]0.3048*7=2.1336[/tex]
The given speed in meters per second is 0.00356 m/sec.
Given that, an object is moving at a speed of 7 feet per minute.
We need to express this speed in meters per second.
How to convert feet per minute to meters per second?Feet per minutes. In SI units [tex]5.08 \times 10^{-3}[/tex] meters per second.
Meters per second is the base unit for measuring velocity or speed in the International System of Units (SI). Speed is a measure of distance travelled over time, velocity is speed in a given direction. 1 meter travelled over a period of 1 second = 1 m/s.
For an approximate result, divide the speed value by 1969.
Now, 7/1969=0.003555
≈0.00356
Therefore, the given speed in meters per second is 0.00356 m/sec.

1) -1 3/5
2) -2/5
3) 1/2
4) 1 3/5
Answer: -2/5
Step-by-step explanation: It's -4/5 multiplied by 1/2 because you you have to find the reciprocal, so you flip 2, so it would become 1/2, then you multiply -4/5 and 1/2, which would get you -4/10, which can be reduced to -2/5. Hope this helps!

In an assessment of the quality of the electrical power system, one measure of quality is the degree to which voltage fluctuations cause light flicker in the system. The perception of light flicker x when the system is set at 380kV was measured periodically (over 10-minute intervals). For transformers supplying heavy industry plants, suppose the light flicker distribution was found to follow (approximately) a normal distribution with % and . If the perception of light flicker exceeds %, the transformer is shut down and the system is reset. How likely is it for a transformer supplying a heavy industry plant to be shut down due to light flicker?

You divide the opposite over the hypotenuse
sin(angle) = opposite/hypotenuse
With respect to reference angle P, the opposite side is QR = 5 since it is the leg furthest from the angle P.
The hypotenuse is always the longest side and always opposite the 90 degree angle (the largest angle of any right triangle).

Answer:
Kindly check explanation
Step-by-step explanation:
________A___ B___ C___ Total
Male____ 9___13___ 6____ 28
Female_ 20__ 19___ 2____ 41
Total___ 29__ 32___ 8____ 69
If one student is chosen at random,
Find the probability that the student got a C:
P(getting C) = (number of C's) / total number
P(getting C) = 8 / 69
Find the probability that the student was female AND got a "C":
P(female and C):
(number of female who got C / total number)
= 2 / 69
Find the probability that the student was male OR got an "B":
P(male OR B) :
(Number of males or B) = (28 + 32) - 13 = 47
= 47 / 90
find the probability that the student got a 'C' GIVEN they are female:______.
P(C given they are female) :
This is the proportion of females who got C
Total Number of females = 41
Females who got C = 2
Hence,
P(C given they are female) = 2 / 41
