Rina8888 [55]

Answer:

Step-by-step explanation:

g(m) = 0

2-4m=0

2=4m

2/4=m

1/2=m------(1

p(1/2)= -3(1/2) - { 2(1/2) + (5- 1/2) } +7

= -3/2 - { 1 + 9/2} +7

= -3/2 - ( 11/2) +7

=-14/2 +7

= -14 + 14 /2

= 0/2

= 0...

since p(m)= 0,

we can say that g(m) is a factor of p(m)

hence, it has been simplified correctly...

Answer:

The same shape but not the same size

Step-by-step explanation:

If two figures have the same shape and the same size, they are defined as congruent.

As long as all the angles and sides are proportionally similar then the shapes have similarity.

The multiplication of frcations in simplest form is 4 3/8

Step-by-step explanation:

We convert the given fractions into simple forms and then multiply them.

Given fractions are:

$1\frac{7}{8} = \frac{15}{8}\\2\frac{1}{3} = \frac{7}{3}$

Multiplying both fractions

$\frac{15}{8} * \frac{7}{3}\\=\frac{15*7}{8*3}\\=\frac{5*7}{8}\\=\frac{35}{8}\\=4\frac{3}{8}$

The multiplication of frcations in simplest form is 4 3/8

Answer:

90% confidence interval for the difference between the two population means

( -23.4166 , -6.5834)

Step-by-step explanation:

Step(i):-

Given first sample size n₁ = 100

Given mean of the first sample x₁⁻ = 178

Standard deviation of the sample S₁ = 35

Given second sample size n₂= 100

Given mean of the second sample x₂⁻ = 193

Standard deviation of the sample S₂ = 37

Step(ii):-

Standard error of two population means

$se(x^{-} _{1} -x^{-} _{2} ) = \sqrt{\frac{s^{2} _{1} }{n_{1} }+\frac{s^{2} _{2} }{n_{2} } }$

$se(x^{-} _{1} -x^{-} _{2} ) = \sqrt{\frac{(35)^{2} }{100 }+\frac{(37)^{2} }{100 } }$

$se(x^{-} _{1} -x^{-} _{2} ) = 5.093$

Degrees of freedom

ν = n₁ +n₂ -2 = 100 +100 -2 = 198

t₀.₁₀ = 1.6526

Step(iii):-

90% confidence interval for the difference between the two population means

$(x^{-} _{1} - x^{-} _{2} - t_{\frac{\alpha }{2} } Se (x^{-} _{1} - x^{-} _{2}) , x^{-} _{1} - x^{-} _{2} + t_{\frac{\alpha }{2} } Se (x^{-} _{1} - x^{-} _{2})$

(178-193 - 1.6526 (5.093) , 178-193 + 1.6526 (5.093)

(-15-8.4166 , -15 + 8.4166)

( -23.4166 , -6.5834)
