Negative 1 and 2thirds divided by -2 1/5

Mathematics
1 answer:
Lena [83]3 years ago
7 0

Answer:

25 / 33

Step-by-step explanation:

(-1 2/3) / (-2 1/5)

(-5/3) / (-11/5)

Division is the same as the inverse of multiplication.

(-5/3) * (-5/11)

Multiply both numerators and multiply both denominators

(-5 *-5) / (3 * 11)

25 / 33

A textile fiber manufacturer is investigating a new drapery yarn, which the company claims has a mean thread elongation of 12 ki
shepuryov [24]

Answer

given,

mean = 12 Kg

standard deviation = 0.5 Kg

assume the observed statistic is = 11.1

 now, \bar{X}=11.1 , \mu = 12 , \sigma = 0.5

assuming the number of sample = 4

n = 4

Hypothesis test:

H₀ : μ≥ 12

Ha : μ < 12

now,

significant level α = 0.05

z* = \dfrac{\bar{X}-\mu}{\dfrac{\sigma}{\sqrt{n}}}

z* = \dfrac{11.1-12}{\dfrac{0.5}{\sqrt{4}}}

     z* = -3.60

Test statistics, Z* = -3.60

P-value

P(Z<-3.60) = 0.002 (from z- table)

P- value = 0.002

now,

reject the value of H₀ when P-value < α

    0.002 < 0.05

since, it is less P-value < α , we have to reject the null hypothesis

Which system of equations is graphed below?
algol [13]

(Pls give brainliest! :D)

Answer:

<em>B</em>

Step-by-step explanation:

<em>You know that the graph intercepts at the point of (4,-2)</em>

<em />

<em>Where x = 4 and y = -2.</em>

<em />

<em>This means that whenever you plug a value of x in the equation it should give the value of y.</em>

<em />

<em>For example when you plug x= 4 into the equation (B), it should look like this.</em>

<em />

<em>4- y = 6, solving for y gives us the value negative 2.</em>

<em />

<em>This means that it does give us this point, however, as the graph shows us, both lines meet at the point which means that both equation should give us this point.</em>

<em />

<em>If we substitute x = 4 in the second equation of b, we should be able to get 3(4) + 4y = 4. Solving for y gives us -2.</em>

<em />

Hope this helps!
