A survey was conducted by an independent price checking company to check an advertiser's claim that it had lower prices than its

Mama L [17]

Answer:

a) critical values ≈ -3.182 and 3.182 shows that there is difference in average prices

b) H0 : μd = 0

Ha : μd ≠ 0

Step-by-step explanation:

a) Determine if there is any significant difference in the average prices

using ∝ = 0.05

and μ( advertiser ) - μ ( competitor ) = μd

test statistic ( t ) = -3.011

df = 3

hence the critical values ( two tailed test ) = -3.182 and 3.182. this shows that there is sufficient evidence to show that there is difference in the average prices

b) state the hypothesis

H0 : μd = 0 ( null )

Alternate hypothesis : Ha : μd ≠ 0

SV is a midsegment of △RTU. If TU=y+38 and SV=y–9, what is the value of y?

pav-90 [236]

Answer:

y = 56

Step-by-step explanation:

the midsegment SV is half the length of the side TU , that is

y - 9 = $\frac{1}{2}$ (y + 38) ← multiply both sides by 2 to clear the fraction

2y - 18 = y + 38 ( subtract y from both sides )

y - 18 = 38 ( add 18 to both sides )

y = 56

Two slits are illuminated by a 348 nm light. The angle between the zeroth-order bright band at the center of the screen and the

Andre45 [30]

Answer:0.369 m

Step-by-step explanation:

Given

Distance between slit and screen is $D=154 cm$

Wavelength $\lambda =348 nm$

Angle between zeroth order bright fringe and Fourth-order bright fringe is $\theta =13.5^{\circ}$

let distance between the slits be d

Distance of n th bright fringe From central Fringe is given by

$y_n=\frac{nD\lambda }{d}$

Also $\tan \theta =\frac{y_4}{D}$

$y_4=\tan (13.5)\cdot 1.54$

$y_4=0.24\times 1.54$

$y_4=0.369 m$
