Complete the expressions that would make them a perfect square trinomial.
a.
x² – 8x+
b. x2 + 20x +
C.
x² – 16x +
d. x2 + 9x +

Answers

Answer:

a) 16

b) 100

c) 64

d) [tex]\frac{81}{4}[/tex][/tex]

Step-by-step explanation:

Perfect square trinomial:

A perfect square trinomial has the following format:

[tex](x \pm a)^2 = x^2 \pm 2ax + a^2[/tex]

a.

x² – 8x

[tex]x^2 - 8x = x^2 - 2ax[/tex]

So 2a = 8, a = 4. Then

[tex]a^2 = 4^2 = 16[/tex]

The perfect square trinomial is [tex]x^2 - 8x + 16[/tex]

b. x2 + 20x +

2a = 20, so a = 10

[tex]a^2 = 10^2 = 100[/tex]

The perfect square trinomial is [tex]x^2 + 20x + 100[/tex]

C.

x² – 16x +

2a = -16, so a = -8.

[tex]a^2 = (-8)^2 = 64[/tex]

The perfect square trinomial is [tex]x^2 - 16x + 64[/tex]

d. x2 + 9x +

[tex]2a = 9[/tex], so [tex]a = \frac{9}{2}[/tex]

[tex]a^2 = (\frac{9}{2})^2 = \frac{81}{4}[/tex]

The perfect square trinomial is [tex]x^2 + 9x + \frac{81}{4}[/tex][/tex]

The points I, J, K and L all lie on the same line segment, in that order, such that the ratio of IJ : JK: KL is equal to 4:6: 1. If IL = 22, find JK.

Answers

Answer:

12

Step-by-step explanation:

First we find how much the ratio is

4:6:1 = 11 which is half of 22

You have to double each in order to get to 22

IJ:JK:KL

4 : 6 : 1 =11

8 : 12 : 2 =22

JK=12

Step-by-step explanation:

Two catalysts may be used in a batch chemical process. Twelve batches were prepared using catalyst 1, resulting in an average yield of 84 and a sample standard deviation of 3. Fifteen batches were prepared using catalyst 2, and they resulted in an average yield of 90 with a standard deviation of 2. Assume that yield measurements are approximately normally distributed with the same standard deviation.
(A) Is there evidence to support the claim that catalyst 2 produces higher mean yield than catalyst 1? Use alpha = 0.01.
(B) Find a 99% confidence interval on the difference in mean yields that can be used to test the claim in part (a). (e.g. 98.76).

Answers

Answer:

Step-by-step explanation:

From the given information:

Let assume:

[tex]\mu_1 =[/tex] population mean for catalyst 1

[tex]\mu_2 =[/tex] population mean for catalyst 2

Then:

Null hypothesis: [tex]\mu_1 \ge \mu_2[/tex]

Alternative hypothesis: [tex]\mu_1 <\mu_2[/tex]

[tex]\alpha= 0.01[/tex]

By using MINITAB software to compute the 2 sample t-test, we have:

Two-Sample T_Test and CI

Sample    N     Mean     StDev      SE Mean

1               12     94.00      3.00       0.87

2              15      90.00     2.00      0.52

Difference = [tex]\mu_1(1)-\mu_2(2)[/tex]

Estimate of difference: -6.00

99% upper bound for difference: -3.603

T-test of difference: 0  (vs <): T-value = -6.22

P.value = 0.000

DF = 25

Both use Pooled  StDev = 2.4900

From above result

the test statistics = -6.00

p-value = 0.00

Decision Rule: To reject [tex]H_o\ \ if \ \ p \le \alpha[/tex]

Conclusion: Provided that p-value is < ∝, we reject [tex]H_o[/tex]. Hence, there is sufficient evidence to support the given claim.

b) From the MINITAB;

The 99% C.I on the difference in the mean yields that can be applied to test the claim in part (a) is:

(r - q)^2 = r^2 - 2qr + q^2, and

(r + q)^2 = r^2 + 2qr + q^2    This is the square of the binomial (r + q).

Answers

Answer:

z = 28

d = 126

Step-by-step explanation:

20 = z-8

20+8= z-8+8

28 = z

d-21 = 105

d-21+21 = 105+21

d = 126

The value of variable d is 126 degrees and value of variable z is 28 in the parallelogram.

What is Parallelogram?

A parallelogram is a simple quadrilateral with two pairs of parallel sides.

We know that the opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure.

So d-21=105

Add 21 on both sides

d=105+21

d=126

and 20=z-8

Add 8 on both sides

20+8=z

28=z

Hence, the value of variable d is 126 degrees and value of variable z is 28 in the parallelogram.

Answers

Answer:

Step-by-step explanation:

Ken grew 4/5 of an inch. 4/5=0.8

Sang grew 3/8 of an inch. 3/8= 0.375

0.8 > 0.375 so Ken grew more.

0.8 - 0.375 = 0.425

So, Ken grew 0.425 more inches than Sang grew. 0.425 is also the same thing as 17/40.
