4 0

12.38 in expanded form is write like:-

10 + 2 + .3 + .08 = 12.38

To write a number in expanded form just means to write the number in a layout and when you add it up it will become the number you needed to write in expanded form.

So, 12.38 written in expanded form is:- 10 + 2 + .3 + 0.8

Hope i helped ya!!

A multinational firm wants to estimate the average number of hours in a month that theiremployees spend on social media while on

elena55 [62]

Answer:

95% of the population spent between 16.8 hours to 26.2 hours on social media per month

Step-by-step explanation:

subtracting 1 from sample size: 83-1= 82
Note Mean=21.5 and standard deviation=2.5
Subtracting confidence interval from 1 and dividing by 2: (1-0.95)/2=0.025
At α=0.025 and dF=82, the t-distribution table gives 1.984
Divide standard deviation by square root of sample size: 21.5/√83= 2.36
Multiplying answer in step 4 by answer in step 5: 2.36×1.984= 4.68
For lower end: 21.5-4.68= 16.82
for upper end: 21.5+4.68=26.18

Given that cos (x) = 1/3, find sin (90 - x)

ddd [48]

Answer:

$\sin(90^{\circ} - x)=\frac{1}{3}$

Step-by-step explanation:

Given: $\cos (x)=\frac{1}{3}$

We have to find the value of $\sin(90^{\circ} - x)$

Since Given $\cos (x)=\frac{1}{3}$

Using trigonometric identity,

$\sin(90^{\circ} - \theta)=\cos\theta$

Thus, for $\sin(90^{\circ} - x)$ comparing , we have,

$\theta=x$

We get,

$\sin(90^{\circ} - x)=\cos x=\frac{1}{3}$

Thus, $\sin(90^{\circ} - x)=\frac{1}{3}$

Use the graph of a translated function below to answer this question

Talja [164]

The graph of the function $y=x^3$ has the point of inflection at the origin. From the diagram you can the that the graph $y=f(x - h) + k$ has the point of inflection at point (-2,-3). So you should translate the graph of the function $y=x^3$ 2 units to the left and 3 units down. This translation is acting on function $y=f(x)$ in the following way:

translation 2 units to the left - $y=f(x+2);$
translation 3 units down - $y=f(x+2)-3.$

Then h=-2 and k=-3.

Answer: correct choice is A.

The explicit rule for a sequence is

pishuonlain [190]

For an explicit formula in its simplified form, we must evaluate the first two terms.

For $a_n=48-11n$ , $a_1=48-11=37$ , and $a_2=48-22=26$ . We see that the common difference is $37-26=-11$ , and $a_1=37$ , so we write,
$a_1=37, \ \ \ a_n=a(n-1)-11$ .

The correct answer is B.
