MSSA PRACTICE TEST 2024

Beginning in June 2004, Raphael noted the price of a stock at the same time twice each year. The graph shows the price of the stock during a three-year period. Which statement is true about the data?

• The price was constantly increasing.

• The price rose at least 10% every six months.

• The price more than tripled during the three-year period.

• The price more than doubled during the three-year period.

Answer explanation

The statement 'The price more than doubled during the three-year period.' is true because the stock price increased from the initial value to more than double by the end of the three-year period.

What fraction is equivalent to 0.27?

• 2/7

• 3/11

• 1/27

• 27/100

Answer explanation

To find the equivalent fraction of 0.27, we can express it as 27/100 since 0.27 = 27/100.

Miko will solve this equation for x in exactly two steps. The equation is 2(x+7) = 5. What is most likely the first step in Miko's solution?

• Divide each side of the equation by 2.

• Divide each side of the equation by 5.

• Subtract 7 from each side of the equation.

• Use the distributive property on the left side of the equation.

Answer explanation

Miko's most likely first step is to divide each side of the equation by 2 to isolate x.

Triangle ABC is shown on this coordinate plane. The triangle is dilated by a scale factor of 3 with point A as the center of dilation. What are the coordinates of vertex B after the dilation?

• (5, 7)

• (6, 6)

• (6, 12)

• (8, 7)

Answer explanation

The coordinates of vertex B after dilation can be found by multiplying the original coordinates by the scale factor of 3. So, (2, 6) * 3 = (6, 18). However, since A is the center of dilation, we need to find the midpoint between A and the new B, which is (6, 6).

The equation w = 3.1t + 6 can be used to estimate w, the weight of a puppy in ounces that is t weeks old. Based on the equation, which statement compares the expected weight of a 1-week old puppy to the weight of a newborn puppy?

• The 1-week old puppy weighs 3.1 ounces more.

• The 1-week old puppy weighs 3.1 ounces less.

• The 1-week old puppy weighs 6 ounces more.

• The 1-week old puppy weighs 6 ounces less.

Answer explanation

The 1-week old puppy weighs 3.1 ounces more.

Rory is looking at a table of x-values and y-values. Which process could Rory use to determine if y can be considered a function of x?

• make sure the x-values follow a pattern

• make sure the y-values follow a pattern

• make sure no two distinct x-values correspond to the same unique y-value

• make sure each unique x-value corresponds to exactly one unique y-value

Answer explanation

make sure each unique x-value corresponds to exactly one unique y-value

Which inequalities are true? Select all that apply.

• √5 > √6

• √3+4 > 3

• π² > 9

• -6 > -2π

• √22 > 5

Answer explanation

The inequalities that are true are: √3+4 > 3, π² > 9, and √22 > 5. These can be verified by evaluating the expressions and comparing the values.

This question has two parts. Be sure to answer all parts of the question. The scatterplot shows the number of bottles of water and the number of soft pretzels sold during different hours at a stadium snack stand. The equation y = x + 0.5 models the line of best fit, where x is the number of soft pretzels sold and y is the number of bottles of water sold. What does the slope of the model represent in this situation?

Evaluate responses using AI:

OFF

Answer explanation

The slope of the model represents the rate at which the number of bottles of water sold increases with each additional soft pretzel sold.

Based on the line of best fit, how many bottles of water could be sold when 22 soft pretzels are sold? Show your work or explain how you know.

Evaluate responses using AI:

OFF

Answer explanation

To find the number of bottles of water sold when 22 soft pretzels are sold, we would look at the line of best fit equation and substitute 22 for the number of soft pretzels. The resulting value would give us the estimated number of bottles of water sold.

Triangle LMN is shown on this coordinate plane. Triangle PQR has these coordinates: P(0, 2), Q(−3, −4), and R(−3, 5). Which transformation can be used to show that Triangle LMN is congruent to Triangle PQR?

• a reflection across the x-axis

• a reflection across the y-axis

• a rotation 180° about point L

• a rotation 180° about the origin

Answer explanation

To show congruence between Triangle LMN and Triangle PQR, a rotation of 180° about the origin is needed, aligning the two triangles perfectly.
