Hello please your question is in-complete attached is the complete question
degree of freedom = -62.90 ( e )
Step-by-step explanation:
The formula for calculating the F-statistic/test statistic is
test - statistic = Coef ( LBW) / SE Coef ( LBW )
= -0.72399 / 0.01151
= - 62.90
the degree of freedom the F-statistic has = -62.90
F-statistic test is any statistical test in which the test statistic has an F-distribution under the null hypothesis. the value of the test can be gotten from running an ANOVA test or regression analysis on the statistical models
The complete question is:
Elizabeth has a lot of jewelry. She has four times as many earrings as watches but half the number of necklaces as earrings. Elizabeth has the same number of necklaces as bracelets. If Elizabeth has 117 pieces of jewelry, has many earrings does she have?
Answer:
Elizabeth has 52 pieces of earrings.
Step-by-step explanation:
- Let the number of Elizabeth's watches = p
- Earrings = 4p (Because she has 4 times as many earrings as watches)
- necklaces = (1/2)4p = 2p (half the number of necklaces as earrings)
=> necklaces = 2p
- bracelets = 2p (same number of necklaces as bracelets.)
Since the total number of pieces of jewelry = 117, the addition of all the jewelry will be 117
That is, watches + earrings + necklaces + bracelets = 117
p + 4p + 2p + 2p = 117
9p = 117
p = 117/9 = 13
Therefore,
p = 13 (watches)
4p = 4×13 = 52 (earrings)
2p = 2×13 = 26 (necklaces)
and 26 bracelets.
Elizabeth has 52 pieces of earrings.
49w² -112w + 64
first, you have to find 2 numbers that add up to equal -112, but also multiply together to get a product of 3136 (49 * 64)
two numbers that add to -112 and multiply to equal 3136 is -56 and -56
we can add them into the equation by putting them in for -112x
49w²-56w-56w+64
we now look at what the first 2 numbers have in common and what the last two numbers have in common
49w² and -56w both have w and 7 in common so we can divide 7w
7w(7w -8)
-56w and 64 both have -8 in common so we can divide by -8
-8(7w-8)
now we take the 2 numbers on the outside and bring down the numbers in the brackets
(7w-8)(7w-8)
(7w-8)²
Answer: last one is the answer
