Answer:

f = 8/5

Step-by-step explanation:

$5 + 5f - 6 = 7\\5f - 1 = 7\\5f = 7 + 1 \\5f = 8\\\\f = \frac{8}{5}$

na2s + hcl _____ nacl + h2s Which of these would represent the coefficients needed to balance this equation? A) 1, 1, 1, 1 B) 1,

USPshnik [31]

Answer:

B) 1, 2, 2, 1

Step-by-step explanation:

In given equation:

Left side: Right Side:

2 Na 1 Na

1 S 1 S

1 H 2 H

1 Cl 1 Cl

To equal the number of Na and H atoms on both sides, HCl and NaCl will have a coefficient of 2 to balance the equation while Na₂S and H₂S will have a coefficient of 1.

1 Na₂S + 2 HCl ⇒ 2 NaCl + 1 H₂S

A local mattress manufacturer wants to know if its manufacturing process is in or out of control and has hired you, a statistics

balandron [24]

Answer:

a. 95.4

b. UCL = 96.07

LCL = 94.73

c. Process is in control

Step-by-step explanation:

a. The computation of estimate mean is shown below:-

$Estimate\ mean = \frac{\Sigma X}{N} \\\\ = \frac{1908.000}{20}$

= 95.4

b. The computation of Upper Control Limit (UCL) and the Lower Control Limit (LCL) for the manufacturing process is shown below:-

$UCL = Mean + \frac{3\times \sigma }{\sqrt{Sample\ size} }$

$UCL = 95.4 + \frac{3\times (0.5)}{\sqrt{0.5} }$

= 95.4 + 0.67082

= 96.07

$UCL = Mean - \frac{3\times \sigma }{\sqrt{Sample\ size} }$

$UCL = 95.4 - \frac{3\times (0.5)}{\sqrt{0.5} }$

= 95.4 - 0.67082

= 94.73

c. The explanation is shown below:-

From the above calculation we can see that the sample lies between LCL AND UCL that is (94.73 ,96.07) ,

The Process is in control

Anita invested $6000, some at 5% and the rest at 6%. If the yearly income is $337.50, what is the amount invested at each rate?

Pepsi [2]

Let the amount invested with 5% interest be x

Therefore, the amount invested with 6% interest will be (6000-x)

It is given that the total interest earned yearly is $337.5. Thus, the equation of interest will be:

$\frac{5}{100}x+\frac{6}{100}(6000-x)=337.5$

Multiplying both sides by 100 we get:

$5x+6(6000-x)=33750$

$5x+36000-6x=33750$

Subtracting both sides by 36000 we get:

$-x=-2250$

$\therefore x=2250$

Thus, the amount invested at 5% is $2250

Therefore, the amount invested at 6% will be $(6000-2250)=$3750

Suppose f′(6)=5 and g′(6)=7. <br> Find h′(6) where h(x)=4f(x)+5g(x)+1.

Nimfa-mama [501]

The value of the derivative of functions h'(6) as requested in the task content is; 55.

<h3>What is the value of h'(6)?</h3>

Since it follows from the task content that the function h(x)=4f(x)+5g(x)+1.

Hence, the derivative of h(x) can be evaluated as;

h'(x)=4f'(x)+5g'(x)

On this note, by substitution, it follows that;

h'(6)=4(5)+5(7)

h'(6) = 55.
