$2/5lb find unit rate

shtirl [24]

Answer:

1$/2.5lb

Step-by-step explanation:

This is a fraction equal to 5 pounds / 2 dollars

We want a unit rate where 1 is in the denominator, so we have to divide the top and bottom by 2.

5 pounds / 2

2 dollars / 2

This should progress to

2.5 pounds/a dollar

This means that the unit rate is 2.5 pounds per dollar.

Arturo is

Brums [2.3K]

Answer:

Yes

Step-by-step explanation:

When there are 2 rows

Number of erasers per row = No. of erasers / No. of rows
Number of erasers per row = 18/2
Number of erasers per row = 9

When there are 3 rows

Number of erasers per row = No. of erasers / No. of rows
Number of erasers per row = 18/3
Number of erasers per row = 6

Therefore, there will be more erasers per row in 2 equal rows than in 3 equal rows.

Events A and B are disjointed.

Llana [10]

Answer:

7/11

Step-by-step explanation:

Two events are disjoint events if they cannot occur at the same time. It is given that A and B are disjointed events, so A and B cannot occur at the same time i.e. the intersection of two disjoint events will be 0.

For two disjoint events A and B:

P(A or B) = P(A) + P(B)

P(A) is given to be 4/11 and P(B) is given to be 3/11. Using these values in the equation, we get:

P(A or B) = $\frac{4}{11}+\frac{3}{11} = \frac{3+4}{11}=\frac{7}{11}$

Use the data consisting of IQ score and brain volume

ArbitrLikvidat [17]

Answer:

The best predicted IQ score is 103.

Step-by-step explanation:

We are given the following regression equation:

$y=100.2+0.00297x$

where y is the predicted IQ score and x is the brain volume.

y is the dependent variable and x is the independent variable.

Significance level = 0.05

We have to find the best predicted IQ score with a brain volume of 998 cubic cm.

We put x = 998 in the equation.

$y=100.2+0.00297(998)\\y=103.16406\\y\approx 103$

Thus, the best predicted IQ score is 103.
