Step-by-step explanation:
Our values are,
Jelly Bean Mix.
The sample for us is n=200
And our proportion (x) is 40 .
We can calculate with this dates the sample proportion and make he test statistic.
We use the formula for Test statistic, that is given by,
We see that our P-value: 0.048 (From the Table)
We note that p-value is less than 0.05, so we should to rejecyt the null hypothesis and conclude that the calim is doubtful
Answer:
22.75 minutes or 22 minutes 45 seconds
Step-by-step explanation:
Okay, this is a working together question. Let’s walk through it together!
Firstly, let’s say the total volume of the swimming pool is x sq.meters
Now, the rate of the smaller hose would be x/65 while that of the larger will be x/35
Now, their combined rate would be x/65 + x/35 = 100x/2275
Now, since the volume is x, the time taken is simply, the volume divided by the joint rate. That is mathematically equal to x divided by 100x/2275
x * 2275/100x = 2275/100 = 22.75 minutes or 22 minutes 45 seconds

Answer:
D
Step-by-step explanation:
a² - b² ← is a difference of squares and is factored in general as
(a + b)(a - b)
42² - 38² ← is a difference of squares and factors as
42² - 38² = (42 + 38)(42 - 38) = 80(4) = 320 → D
