A study involving x = temperature (Celsius) and y = milk pH reported the following results: x 4 4 24 24 25 38 38 40 45 50 55 56 60 67 70 78
y 6.85 6.79 6.63 6.65 6.72 6.62 6.57 6.52 6.50 6.48 6.42 6.41 6.38 6.34 6.32 6.34
Do these data suggest that there is a useful linear relationship between temperature and pH? State and test the relevant hypotheses using a significance level of 0.05.

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
