Juanita begins to factor an expression as shown.x2 + 3x – 18 = (x + )(x – )

The numbers that should be placed in the boxes, from left to right, are
.

Answers

Answer 1

Answer: 6 and 3. To find this answer, you simply need to factor the expression on the left-hand side of the equals sign. To factor the expression, you need to find 2 numbers which add up to be 3 and multiply to be -18. The two numbers which do this are 6 and -3. Since you want a positive 3, you know that the 6 goes in the left box and the 3 goes in the right box.

On a finance exam, 15 accounting majors had an average grade of 90. On the same exam, 7 marketing majors averaged 85, and 10 finance majors averaged 93. What is the weighted mean for all 32 students taking the exam?

Answers

Answer:

89.84375

Step-by-step explanation:

Given that on a finance exam, 15 accounting majors had an average grade of 90. On the same exam, 7 marketing majors averaged 85, and 10 finance majors averaged 93.

To find weighted mean.

Here weights can be considered as number of majors in each subject

$Marks x 90 85 93\nWeights 15 7 10\nProduct 1350 595 930\n$

Weighted total = 1350+595+930 = 2875

Weighted mean = weighted total/total students

$=(2875)/(32) =89.84375$

Consider the division of 4h2 + 2h + 6 by 2h. What are the values of A and B? A = 2 and B = 1 A = 2h and B = 1 A = and B =2/h A = 1/2h and A= h/2 and B= 1/2h

Answers

Answer:

A = 2h and B = 1

Step-by-step explanation:

When dividing 4h^2 + 2h + 6 by 2h, we can apply distributive property as follows:

$(4h^2 + 2h + 6)/(2h)$

$(4h^2)/(2h) + (2h)/(2h) + (6)/(2h)$

$2h + 1 + (3)/(h)$

which can be represented as A + B + C, where A = 2h, B = 1 and C = 3/h

4h2 you add 3 then subtract that of 5A=to B then you divide that from 5.

A rectangular box has dimensions 4 by 5 by 2 . Increasing each dimension of the box by the same amount yields a new box with volume six times the old. Use the ALEKS graphing calculator to find how much each dimension of the original box was increased to create the new box. Round your answer to two decimal places.

Answers

Answer:

2.68 units

Step-by-step explanation:

We are given that a rectangular box has dimensions 4 by 5 by 2.

We have to find that how much each dimension of the original box was increased to create the new box

Let x be the increased value in each dimension

We know that volume of rectangular box=lbh

Volume of original box= $4* 5* 2$ =40 cubic units

Volume of new box = $6* 40=240 cubic units$

Dimension of new box= $(x+4)(5+x)(2+x)$

Volume of new box=240

$(x+5)(x+4)(x+2)=240$

$x^3+11x^2+38x+40-240=0$

$x^3+11x^2+38x-200=0$

By graph we get

x=2.679

Round to two decimal places then we get

x=2.68

Hence, each dimension was increased by 2.68 units

researchers wish to test the effect of living environment on cholesterol level they take a sample of people from a rural area and a sample of people from an urban area and compare their cholesterol levels. what would be the best statistical test for them to utilize? group of answer choices two-sample t-test anova linear regression chi-square

Answers

To test the effect of living environment on cholesterol levels using samples from rural and urban areas, the best statistical test to utilize would be the two-sample t-test.

The two-sample t-test is appropriate in this case because it compares the means of two independent groups (rural and urban residents) to determine if there is a significant difference between their cholesterol levels.

This test will help researchers determine if living environment has an impact on cholesterol levels.
