Answer:
b = -3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
6b+14=−7−b
6b+14=−7+−b
6b+14=−b−7
Step 2: Add b to both sides.
6b+14+b=−b−7+b
7b+14=−7
Step 3: Subtract 14 from both sides.
7b+14−14=−7−14
7b=−21
Step 4: Divide both sides by 7.
b= -3
Answer:
w = 5.2
Step-by-step explanation:
4(2.25w + 3.1) - 2.75w = 44.9
9w + 12.4 - 2.75w = 44.9
6.25w + 12.4 = 44.9
6.25w = 32.5
w = 5.2
Answer: Scalene triangle
Step-by-step explanation:
A Scalene triangle has all of its three lengths to be different. The traingle above can not be an equilateral triangle too because all the sides aren't equal.
Also, it's not an isosceles triangle since two of its sides are not thesame. It's not a right angle triangle as the square of the hypothenuse isn't equal to the addition of the square of the other two sides.
There is no sufficient evidence to suggest that men and women have equal success in challenging calls. This was illustrated in the hypothesis.
<h3>How to compute the value?</h3>
It should be noted that based on the information given, P1 will be:
= 424/1436
= 0.295
P2 will be:
= 222/754
= 0.294
The value of the test statistic will be:
= (424 + 222)/(1436 + 754)
= 646/2190
= 0.2949
In this case, the value of the test statistic falls on the rejection region, therefore, there is no sufficient evidence to suggest that men and women have equal success in challenging calls.

<span>Using what's given, you'd have $2800 = p x 0.04 x 3.5. </span>
<span>We don't know the principle so you'd leave the variable there and convert 4% interest to 0.04. Solve by getting 2800 = p(0.14) then divide each side by 0.14 and get p=20,000. So your principle, or the amount deposited, should be $20000. You can solve by plugging in your answer (20000 x 0.04 x 3.5 = 2800)
</span>Interest = Principal * rate * time
<span>2800 = x * 4% * 3.5 </span>
<span>2800/(4% *3.5) = x </span>
<span>20000 = x
</span>
