What is the lowest common multiple of 42 and 63?

gtnhenbr [62]

Because 42 doesn't go into 63, you have to go larger. Start by multiplying 63 by 2.

63*2=126

42 goes into 126 3 times even, so the LCM of 42 and 63 is 126 :)

Quickly IT is Due an a hour PLease show work show me how to do it and No links

djyliett [7]

Answer: 4

Step-by-step explanation:

-6x = -24 divide both sides by -6 to isolate x

x = -24/-6

x = 4

Checking my work (plug in 4 for x and solve)

-6x = -24

-6(4) = -24

-24 = -24 it's correct!

Answer:

The calculated value t = 2.038< 2.145 at 0.05 level of significance

Null hypothesis is accepted

There is the average rate is less than μ ≤ 4

Step-by-step explanation:

Step(i):-

The Population of the mean 'μ' =4

sample size 'n' = 16

sample mean 'x⁻' = 4.53

given sample standard deviation 's' = 1.04

level of significance α = 0.05

Step(ii):-

Null hypothesis:H₀ : There is no significance difference between two means

Alternative hypothesis : H₁: There is significance difference between two means

Test statistic

$t = \frac{x^{-} - mean}{\frac{S}{\sqrt{n} } }$

$t = \frac{4.53-4}{\frac{1.04}{\sqrt{16} } }$

t = 2.038

Degrees of freedom ν = n-1 = 16-1 =15

t₀.₀₂₅ = 2.145

Conclusion:-

The calculated value t = 2.038< 2.145 at 0.05 level of significance

Null hypothesis is accepted

There is the average rate is less than μ ≤ 4

Rewrite each of the following statements in the form "∀ _____ x, _____." (a) All dinosaurs are extinct. ∀ x, . (b) Every real nu

jasenka [17]

Answer:

See below

Step-by-step explanation:

Essentially, we have to replace "quantifier words" like "All", "Every" by the universal quantifier ∀.

a) ∀ dinosaur x, x is extinct.

b) ∀ real number x, x is positive, negative, or zero.

c) ∀ irrational number x, x is not an integer.

d) ∀ logician x, x is not lazy.

e) ∀ integer x, x²≠ 2,147,581,953.

f) ∀ real number x, x²≠ -1.

In a) and b) we replace the words without major changes. In the other statements, we modify the statement using negation. For example, "No irrational numbers are integers." is equivalent to "Every irrational number is not integer".
