Answer:
7(x times y)
Step-by-step explanation:
Product means multiply, so it wants you to multiply two numbers and multiply THAT by 7. So we will use two variables, in this case, I will use x and y. X times y. 7 Times that.
Answer:
Where a = 2 , b= 3, c= -5, replacing we have this:
And simplifying we got:
And the two solutions are:
And the correct options are:
B and C
Step-by-step explanation:
We have the following equation given:
And if we use the quadratic formula given by:
Where a = 2 , b= 3, c= -5, replacing we have this:
And simplifying we got:
And the two solutions are:
And the correct options are:
B and C
Answer:
(c) H0 should be rejected
Step-by-step explanation:
Null hypothesis (H0): population mean is equal to 5
Alternate hypothesis (Ha): population mean is greater than 5
Z = (sample mean - population mean) ÷ (sd/√n)
sample mean = 5.3, population mean = 5, sd = 1, n = 500
Z = (5.3 - 5) ÷ (1/√500) = 0.3 ÷ 0.045 = 6.67
Using the normal distribution table, for a one tailed test at 0.01 significance level, the critical value is 2.326
Conclusion:
Since 6.67 is greater than 2.326, reject the null hypothesis (H0)
Answer:
16 and 3/4 is 7/4
Step-by-step explanation:
Answer:
x = 42.9 m
Step-by-step explanation:
Corresponding sides of similar triangles MAB and MNP are proportional. This means ...
x/MP = MA/MN
However, we don't have a number for MA yet, so we need to find it.
MA +AN = MN
MA = MN - AN subtract AN
MA = 67.2 m - 32 m = 35.2 m
Now, we can use this to find x.
x = MP · (MA/MN) = (81.9 m) · 35.2/67.2
x = 42.9 m
