The missing # is 3 & 6
(X+2)(x+3) = x^2+ 5x+6
Jamal because he has a higher percentage of shots made 78%>62%
Answer:
The best thing to do here is to put each of these into fractions, with the total (31) as the denominator.
14/31= silver
6/31= black
8/31= copper
3/31= various colours.
As you're looking for the keys that are silver or copper, you've got to add the two denominators together, which gives you 14+8= 22.
This cannot be simplified further, therefore, the probability of choosing either a silver or copper key is 22/31.
Hope this answer helps you :)
Have a great day

Answer: b. H0: μ ≥ 5; Ha: μ < 5
Step-by-step explanation:
The null hypothesis (H0) tries to show that no significant variation exists between variables or that a single variable is no different than its mean.
While an alternative Hypothesis (Ha) attempt to prove that a new theory is true rather than the old one. That a variable is significantly different from the mean.
The mean is 5 years and they claim it will perform for more than 5 years.
Therefore, for the case above;
H0: μ ≥ 5; Ha: μ < 5
Note: a null hypothesis must always include an equal to sign.
Find slope: parallel lines have same slope
−x+3y=6
+x +x
----------------
3y=x+6
3/3y=x/3+6/3
y=1/3x+2
Slope=1/3
Use slope and point (3, 5) to find b, y- intercept
y=mx+b
(5)=(1/3)(3)+b
5=1+b
5-1=1-1+b
4=b
Now we put it all together using m=1/3 and b=4
y=1/3x+4
