The answer to your question is 3
To solve for d, it is important to remember that we can only add or subtract like terms. Also, that we have to isolate the variable should be solved to one side and all others to the other side. We do as follows:
<span>−2/3x 3/8x = −7/12−1/4x
</span><span>−2/3x 3/8x = −7/12−1/4x
1/4x = </span> −7/12−1/4x
1/2x = -7/12
x = -7/6
Answer:
The answer is: d > -3
Step-by-step explanation:
-7d + 8 > 29
Solve for d:
-7d > 21
d > 21/-7
d > -3
Proof:
-7d + 8 > 29
-7(-3) + 8 = 29
21 + 8 = 29
29 = 29, therefore any number d greater than -3 fulfills the inequality.

Answer: 0.2134
Step-by-step explanation:
Given : Mean readings on thermometers =
Standard deviation =
We assume that the readings on thermometers are normally distributed.
Let x be the random variable that represents the reading on a random thermometer.
To find z-score :
For x = -0.99
For x= -0.32
By using the standard normal distribution table , the probability that a randomly selected thermometer reads between -0.99 and -0.32 will be :-
