Explanation: To find any value of x, you have to get it alone. As -1.4 is being subtracted from 0.7x, you’d do the opposite of the order of operation that it’s doing. So because -1.4 is negative, (being subtracted), you’d have to add -1.4 on both sides of the equation to eliminate the -1.4 from being near the 0.7x. You’re then left with 0.7x = -3.5 + 1.4
You then add those up (-3.5 + 1.4) giving you (-2.1) as your final answer and you’re left with 0.7x = -2.1. You then divide 0.7 from both sides to get x alone, leaving you with -3 as your final answer!
Hope this helps!

A researcher reports that the standard deviation in population is A is q= 2.3 and the standard deviation in population B is q=4.3. Which population is associated with the highest power to detect an effect?
Answers
Answer:
Population A
Step-by-step explanation:
Usually in statistics, the more we increase the sample size, the more the standard deviation decreases. Similarly, the more we decrease the sample size, the more the standard deviation increases.
Finally, the more the standard deviation or error of Variance the lesser the power to detect an effect.
In this question, Population B has a greater standard deviation and thus would not have as much power as Population A in detecting an effect.
Thus Population A with standard deviation of 2.3 will have highest power to detect an effect.

In this case, distributive property is when a number or you could call it integer, multiplies with another set of number inside parentheses ().
Your answer was wrong, because 6 x 7=42, and that's not equal to the other side of numbers.
The top one is addition, so that's a no.
The second one's not exactly in the form you want it to be for it to be the same as the left side.
The third one shows distributive property in two ways, which give you the same result, so that would be the correct answer.

[tex]\Huge\boxed{D.14.6}[/tex]
Step-by-step explanation:
Hello There!
We can solve for x using trigonometry
More specifically the law of sines
In the image you can see that a side length divided by sin(its opposite angle) is equal to another side length divided by sin(its opposite angle)
so to find x we use this equation
[tex]\frac{x}{sin59} =\frac{17}{sin90}[/tex]
step 1 multiply each side by sin 59
now we have
[tex]x=\frac{17sin59}{sin90}\\x = 14.6[/tex]
so we can conclude that x = 14.6

Step-by-step explanation:
Based on the inscribed quadrilateral theorem, the opposite angles of a cyclic quadrilateral are supplementary.
Thus:
m<B + m<D = 180°
Substitute
m<B + 87° = 180°
m<B = 180° - 87°
m<B = 93°

a) The average rainfall of the last week was 35 mm. If the records of daily
rainfall from Sunday to Friday were 45 mm, 22 mm, 28 mm, 36 mm, 30 mm
and 24 mm, find the rainfall on Saturday.
Answers
Answer:
The rainfall on Saturday was of 60 mm.
Step-by-step explanation:
Average rainfall:
The average rainfall is given by the total rainfall divided by the number of days(7). So
If the records of daily rainfall from Sunday to Friday were 45 mm, 22 mm, 28 mm, 36 mm, 30 mm and 24 mm
On Saturday it was of x mm. So
[tex]35 = \frac{45 + 22 + 28 + 36 + 30 + 24 + x}{7}[/tex]
[tex]185 + x = 245[/tex]
[tex]x = 245 - 185[/tex]
[tex]x = 60[/tex]
The rainfall on Saturday was of 60 mm.

An airplane descends 3.5 miles to an elevation of 5.25 miles. Find the elevation of the plane before its
descent.
Before its descent, the plane was at an elevation of
miles.
Answers
Answer: The initial elevation of the plane was 8.75 miles.
Step-by-step explanation:
Suppose that the initial elevation of the plane is E.
Then the plane descends 3.5 miles.
Then the new elevation of the plane will be:
E - 3.5 miles.
Now, we know that the new elevation of the plane is 5.25 miles, then:
E - 3.5 miles = 5.25 miles.
Now we need to solve this for E.
To solve this, we can add the same number to both sides of the equation, so we can add 3.5 miles to both sides to get:
(E - 3.5 miles) + 3.5 miles = 5.25 miles + 3.5 miles
E + (3.5 miles - 3.5 miles) = 5.25 miles + 3.5 miles
E = 8.75 miles.
The initial elevation of the plane was 8.75 miles.

Answer:
diameter = 2.5 feet
Step-by-step explanation:
Circumference of a circle is given as C = πd
Circumference of the tree trunk = 7.85 ft
π = 3.14
Diameter of the tree trunk = d
Thus:
7.85 = 3.14*d
Divide both sides by 3.14
7.85/3.14 = 3.14*d/3.14
2.5 = d
d = 2.5 ft
