Mr. McGill is solving the following problem: 42x=163. Mr. McGill set 2x=3 and got x=32 as his answer. Tell the mistake Mr. McGill made and tell the correct answer.

Answers

Answer 1

Answer:

The mistake McGill made was to eliminate 4 and 16 from both sides before solving fro x

Step-by-step explanation:

Given the expression

42x = 163

To get the values of x, we are to divide both sides by the coefficient of x i.e 42 as shown;

42x = 163

42x/42 = 163/42

x = 163/42

x = 3.88

Hence the mistake McGill made was to eliminate 4 and 16 from both sides before solving fro x

The probability that a person cannot read is 0.85 what is the probability that 2 people selected at random will be unable to read

Answers

Answer: 0.7225

Step-by-step explanation:

Since the probability that a person cannot read is 0.85. The probability that 2 people selected at random will be unable to read will be gotten by multiplying the value of the probability given twice. This will be

= P(not read) × P(not read)

= 0.85 × 0.85

= 0.7225

Therefore, the probability that 2 people selected at random will be unable to read is 0.7225

y=2x^2+12x+14 in vertex form

Answers

Answer:

y = 2(x + 3)² - 4

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Using the method of completing the square

y = 2x² + 12x + 14 ← factor out 2 from the first 2 terms

  = 2(x² + 6x) + 14

To complete the square

add/subtract ( half the coefficient of the x- term)² to x² + 6x

y = 2(x² + 2(3)x + 9 - 9 ) + 14

  = 2(x + 3)² - 18 + 14

  = 2(x + 3)² - 4 ← in vertex form

Are the ratios 18:9 and 2:1 equivalent?

Answers

Answer:

Yes

Step-by-step explanation:

[tex]\frac{18}{9} =\frac{2}{1}[/tex]

The two ratios are,

→ 18 : 9 and 2 : 1

We have to find,

→ whether the ratios are equivalent?

Now simplify the first ratio,

→ 18(÷9) : 9(÷9) = 2 : 1

→ 2 : 1 = 2 : 1

Yeah, the two ratios are equivalent.

no link need right answer105 Years of GreatnessSAN JUAN, Puerto Rico. Emilio "Millito" Navarro never got to play in the major leagues. Still, he was considered to be one of baseball's greats. Navarro, who began his career playing for the Negro Leagues, died on April 30, 2011, in his Caribbean homeland of Puerto Rico. He was 105. In his old age, Navarro was believed to be the oldest living professional baseball player."It is a tremendous loss, but they were 105 years of greatness," said Eric Navarro Rivera, one of Navarro's grandsons, adding, "He gave his all to everybody."Navarro was born on September 26, 1905, in Patillas, Puerto Rico. He became a baseball player at age 17. Before that, Navarro was known as a local champion in three track events.Despite his athletic abilities, Navarro did not have the same opportunities as white baseball players. As a minority, he was not permitted to join the major leagues. Instead, he was given a chance to play in the Negro Leagues, which were founded in 1920 to provide a platform for African-American baseball players. Many baseball teams had hired black players during the 19th century, but by 1900 or so, racism brought about a change in policy. Baseball was racially segregated until 1947, when Jackie Robinson, who was African American, was recruited to the major leagues. Navarro, a 5-foot, 5-inch (165-centimeter) infielder known for his base-running skills, became the first Puerto Rican to play in the Negro Leagues.Navarro was a shortstop and leadoff hitter for the New York-based Cuban Stars of the Eastern Colored League in 1928. He achieved a batting average of .337 the following year. Despite his accomplishments, Navarro recalled experiencing racial discrimination."Back then, there was a lot of racism...," Navarro said. "We [minority] players suffered a lot during that time because we even had to go to different restaurants [than white people]."Navarro left the Negro Leagues after only a couple of years. He played in the Dominican Republic with the Escogido Lions and in Venezuela with the Magallanes and other teams. In Puerto Rico, he was the second baseman for the Ponce Lions for nearly two decades. After retiring from professional baseball, Navarro worked as a coach and an athletic teacher at schools in the Puerto Rican towns of Ponce and Caguas. He also raised a family."He was an... excellent father," said Eric Navarro Torres, one of his sons. "He instilled us with honesty and above all respect for everybody."Navarro appeared on a major league ball field only oncein 2008, at the age of 103. He threw out a first pitch before a game at Yankee Stadium. He warmed up his arm, waved his hat, and made a 30-foot (9.1-meter) toss to catcher Jorge Posada. Asked how the sport had changed since he played, Navarro's eyes widened and he mentioned the high salaries that today's players enjoy."I made $25 a week," he said through a translator.The Associated Press contributed to this story.hint:This question asks about when events happened.
