F(x) = 4x + 7, g(x) = 3x2

Mathematics
1 answer:
Luda [366]3 years ago
7 0

Answer:

(1)

(f+g)(x)=3x^2+4x+7

(2)


Step-by-step explanation:

we are given

f(x)=4x+7

g(x)=3x^2

we have to find (f+g)(x)

we can write

(f+g)(x)=f(x)+g(x)

now, we can plug values

and we get

(f+g)(x)=4x+7+3x^2

we can also write as

(f+g)(x)=3x^2+4x+7

so, answer is

(f+g)(x)=3x^2+4x+7

A researcher wishes to estimate the proportion of X-ray machines that malfunction. A random 275 sample of machines is taken, and
Dominik [7]

Answer:

Following are the solution to the given question:

Step-by-step explanation:

95\% Confidence Interval for both the percentage of all x-ray machines

p = the machinery's share is not working:

= \frac{228}{275}\\\\ = 0.829

\text{Margin of Error} = Z_{(\frac{\alpha}{2})} \times \sqrt{( p \times (1-p)}{n})

                         = 1.96 \times \sqrt{(0.829 \times \frac{0.171}{275})} \\\\= 1.96 \times 0.023 \\\\= 0.045

Lower 95\% Confidence interval = p - error margin = 0.829 - 0.045 = 0.784

Upper 95\% Confidence Interval = p + error margin= 0.829 + 0.045 = 0.874

So, 95\% Confidence Interval = ( 0.78 , 0.87 )

BRAINLIEST can someone please help!!!!!
Zielflug [23.3K]

I don't know about the first one but for the second one:

{2}^{3x + 2}  -  {2}^{3x}  = 48 \\ \Leftrightarrow {2}^{3x}  {2}^{2}  -  {2}^{3x}  = 48 \\ \Leftrightarrow  {2}^{3x} ( 4  - 1) = 48 \\ \Leftrightarrow 3 \times  {2}^{3x}  = 48 \\ \Leftrightarrow  {2}^{3x}  = 16 \\ \Leftrightarrow  {2}^{3x}  =  {2}^{4}  \\ \Leftrightarrow 3x = 4\Leftrightarrow x =  \frac{4}{3}
