At a concession stand, five hot dog(s) and two hamburger(s) cost $11.75; two hot dog(s) and five hamburger(s) cost $11.00. Find
serg [7]

Answer:

x:hot dogs

y: hamburger

5x + 2y = 11.75

2x + 5y = 11.00

10x + 4y = 23.50

-10x - 25y = -55.00

-21y = -31.50

y = $1.50 each hamburger

2x + 5(1.50)= 11.00

2x + 7.50 = 11.00

2x = $3.50

x = $1.75 each hot dog

A survey for brand recognition is done and it is determined that​ 68% of consumers have heard of Dull Computer Company. A survey
Crank

Answer:

It would be significant

Step-by-step explanation:

Population proportion of consumers who recognize the company name = 68% = 0.68

If 634 consumers out of the 800 randomly selected consumers recognize the company name, sample proportion = 634/800 = 0.7925.

It is significant to get 634 because the sample proportion of consumers who recognize the company name is greater than the population proportion.

Find all the missing elements:
Evgesh-ka [11]

Answer:

a=10.8; c=4.3

Step-by-step explanation:

The sum of all the angles in a triangle is 180 degrees.

Two of the angles are given as 40 deg and 120 deg.

Subtract the measures of both from the sum to get the last angle:

180-40-120=20; ∠C=20°

Using Law of Sines: \frac{a}{sinA}=\frac{b}{sinB}=\frac{c}{sinC}

\frac{a}{sin120}=\frac{8}{sin40}; a=\frac{8*sin120}{sin40}; a=10.77837084

\frac{c}{sin20}=\frac{8}{sin40}; a=\frac{8*sin20}{sin40}; c=4.25671109
