What are the equivalent fractions for 2 1/5 and 1 5/6 using 30 as the common denominator
Anuta_ua [19.1K]

Answer:

2 6/30 and 1 25/30

Step-by-step explanation:

First, you need to find 30÷5 and 30÷6. You do this because you need to know the multiplier when you create an equivalent fraction. 30÷5 is 6 and 30÷6 is 5. 2 1/5. You need to multiply the 1 and 5 by 6, that is 2 6/30. 1 5/6. 5 and 6 multiplied by 5 is 25 and 30. 1 5/6=1 25/30

Find the minimum value of the region formed by the system of equations and functions below.
Naily [24]

Answer:

  A.  -12

Step-by-step explanation:

A graph shows the vertices of the feasible region to be (0, 6), (3, 0) and (0, -3). Of these, the one that minimizes f(x, y) is (0, -3). The minimum value is ...

  f(0, -3) = 3·0 + 4(-3) = -12

_____

<em>Comment on the graph</em>

Here, three regions overlap to form the region where solutions are feasible. By reversing the inequality in each of the constraints, <em>the feasible region shows up on the graph as a white space</em>, making it easier to identify. The corner of the feasible region that minimizes the objective function is the one at the bottom, at (0, -3).

The difference of two sample means is 22, and the standard deviation of the difference of the sample means is 10. The difference
taurus [48]

Answer:

The 95% confidence interval for the difference of the two populations means is ( 2.4, 41.6)

Step-by-step explanation:

Confidence intervals are usually constructed using the formula;

point estimate ± margin of error

In this question we are required to construct a 95% confidence interval for the difference of two populations means. The point estimate for the difference of two population means is the difference of their sample means which in this case is 22.

Assuming normality conditions are met, since we have no information on the sample sizes, the margin of error will be calculated as;

margin of error = z-score for 95% confidence * standard deviation of the difference of the sample means

The z-score associated with a 95% confidence interval is 1.96

The standard deviation of the difference of the sample means is given as 10

The 95% confidence interval for the difference of the two populations means is thus;

22 ± 1.96(10) = 22 ± 19.6 = ( 2.4, 41.6)

Solve x+12/x+4=×/x+8
Morgarella [4.7K]
Cross multiply...
Thus,
x(x+4)=(x+12)(x+8)
expand...
x^2+4x=x^2+8x+12x+96
Simply both sides of the equation.
x^2+4x=x^2+20x+96
simply further by adding ask like terms...
-16x=96
Solve for x by making x the subject.
therefore
x=-6.
