Answer:
B. 1.17
Step-by-step explanation:
The z-score is:
z = (x − μ) / σ
z = (67.1 − 64.4) / 2.3
z = 1.17
Applying the Pythagorean theorem, the measure of the other leg, to the nearest tenth, is: 2.6 cm.
<h3>What is the
Pythagorean Theorem?</h3>
In a right triangle, where the lengths of its two legs are a and b, and the hypotenuse length is c, the Pythagorean theorem states that: c² = a² + b².
Given the following parameters of the right triangle:
- c = 4 cm
- a = 3 cm
- b = ? (other leg)
Apply the Pythagorean theorem:
b = √(4² - 3²)
b = 2.6 cm (nearest tenth)
Thus, applying the Pythagorean theorem, the measure of the other leg, to the nearest tenth, is: 2.6 cm.

Answer: (3x+2)(x+4)
Step-by-step explanation:Explanation:
3x2+10x−8
first multiply
3
with −8
and we get −24
then find two numbers that if we add or subtract we get
+10
and if we multiply we get
−24
and the numbers are
+12
and
−2
then we place those numbers as follow :-
3x2+12x−2x−8
then we group them
(3x2+12x)(−2x−8)
now take the common factor out.3x(x+4)−2(x+4)
then group the numbers outside of the brackets
(3x−2)(x+4)
Answer:
The equation for the problem is:
The amount of bracelets you should sell is the price of the soccer cleats divided by 0.75
Step-by-step explanation:
Let's call <em>b</em> the amount of bracelets and <em>s</em> the price of the soccer cleats.
If you make a profit of $0.75 for every bracelet you sell, then 0.75 times the amount of bracelets sold should be equal to the price of the soccer cleats.
This can be written like this:
<em>(this is the equation)</em>
As b (amount of bracelets) is our unknown variable, then that's the term we should isolate. To do so we divide each side of the equation by 0.75
<em>(this is the amount of bracelets you should sell)</em>
Then, the equation for the problem is:
and the amount of bracelets you should sell is the price of the soccer cleats divided by 0.75
