B. Ren spends $5 on souvenirs, he wants to keep the same ratio, how much does he spend on snacks

B- (snacks- 2.5) (games- 2) (souvenirs- 5)


C. Both spend $40 on snacks, they want to keep their original ratio, who spends more on souvenirs?

C. Ratios

Sinea- (snacks- 40) (game- 64) (souvenirs- 96)

look at the table in the problem 4 alex drove a distince between 2 cities in the table.he said that he drove about 2,000 miles.W
luda_lava [24]

The cities Alex could have drove between whose distance is about 2000 miles when rounded to the <em>nearest thousand</em> are : <em>Chicago to San Francisco</em> and <em>Atlanta to Los Angeles</em>

<u>From the table attached which shows the distance in miles between two cities in the United States</u> :

  • Distance between Chicago to San Francisco = 2131

  • Distance between Atlanta to Los Angeles = 2173

Only the distances between these two cities would give a value of 2000 miles when <em>rounded to the nearest thousand mile </em>

The other distances in the table will round to 1000 miles when <em>rounded to the nearest thousand mile</em>.

Prove Sin3theta = 3sintheta - 4sin^3theta
trapecia [35]

Express the left hand side as

sin3theta=sin(theta+2theta)

now expand the right side of this equation using color(blue)"Addition formula"

color(red)(|bar(ul(color(white)(a/a)color(black)(sin(A±B)=sinAcosB±cosAsinB)color(white)(a/a)|)))

rArrsin(theta+2theta)=sinthetacos2theta+costhetasin2theta.......(A)

color(red)(|bar(ul(color(white)(a/a)color(black)(cos2theta=cos^2theta-sin^2theta=2cos^2theta-1=1-2sin^2theta)color(white)(a/a)|)))

The right hand side is expressed only in terms of sintheta's

so we use cos2theta=1-2sin^2theta........(1)

color(red)(|bar(ul(color(white)(a/a)color(black)(sin2theta=2sinthetacostheta)color(white)(a/a)|)))........(2)

Replace cos2theta" and " sin2theta by the expansions (1) and (2)
into (A)

sin(theta+2theta)=sinthetacolor(red)((1-2sin^2theta))+costhetacolor(red)((2sinthetacostheta)

and expanding brackets gives.

sin(theta+2theta)=sintheta-2sin^3theta+2sinthetacos^2theta....(B)

color(red)(|bar(ul(color(white)(a/a)color(black)(cos^2theta+sin^2theta=1rArrcos^2theta=1-sin^2theta)color(white)(a/a)|)))

Replace cos^2theta=1-sin^2theta" into (B)"

rArrsin(theta+2theta)=sintheta-2sin^3theta+2sintheta(1-sin^2theta)

and expanding 2nd bracket gives.

sin(theta+2sintheta)=sintheta-2sin^3theta+2sintheta-2sin^3theta

Finally, collecting like terms.

sin3theta=3sintheta-4sin^3theta="R.H.S hence proven"

An ANOVA procedure is applied to data obtained from four distinct populations. The samples, each comprised of 15 observations, w
otez555 [7]

Answer:

a. 3 and 56, respectively.

Step-by-step explanation:

The computation of the degrees of freedom for the numerator and denominator for the critical value of F is given below:

k = 4

n = 15

Total degree of freedom is

= nk - 1

= 59

For numerator, it is

= k -1

= 4 - 1

= 3

and for denominator it is

= T - (k -1 )

= 59 - 3

= 56
