Let me try this

In order to solve this, we are going to use PEMDAS. If you have not heard of PEMDAS, it stands for parenthesis, exponents, multiplication, division, addition, subtraction. So, lets start with parenthesis. You would do parenthesis first. How do you do that? You just do the math in between the parenthesis. We would do exponents first. Its basically a number saying how much times to multiply the digit it is attached to. So, 3x3. We would then do subtraction, because multiplication, division nor addition is found next. 9-6 would be 3. Now, we would do multiplication next outside of the parenthesis. 3x4 = 12. Lets move on to division. 8 divided by 2 is 4. We would go to addition. 12+4 is 16. And lastly, subtraction. 16-5 is 11. The answer is 11.

Hope this helps.

Answer:

32m

Step-by-step explanation:

because we know that 3cm = 4 m, we can replace the top length with 4m, we also know that 6cm must equal 8m because of 3cm ×2 = 6cm so 4m ×2 = 8m. now we know 2of the sides so the area is just 4m ×8m because area = length times width. 4m × 8m = 32m

Which of the following shows the true solution to the logarithmic equation 3 log Subscript 2 Baseline (2 x) = 3 x = negative 1 x

sineoko [7]

The equation which shows the true solution to the given logarithmic equation is,

$x=1$

<h3>What is power rule of logarithmic function?</h3>

The power of the log rule says that the number written in the front of the logarithmic function can be raised to the power of the logarithmic function.

For example,

$n\log_b(M)=\log_b(M)^n$

Given information-

The logarithmic equation given in the problem is,

$3\log_2(2x)=3$

Using the power rule of the logarithmic function,

$\log_2(2x)^3=3$

Using the exponent rule of the logarithmic function the above equation can be written as,

$(2x)^3=3$

Solve it further,

$8x^3=3\\x^3=1\\x=1$

Hence, the equation which shows the true solution to the given logarithmic equation is,

$x=1$

You start at (3, -3). You move down 1 unit and left 2 units. Where do you end?

Maslowich

Your end position is 1, -4)

<h3>How to determine your end position?</h3>

The start position is given as

Start = (3, -3)

The movement can be represented using the following translation rule

(x, y) = (x - 2, y - 1)

When the above translation rule is applied, we have:

End = (3 - 2, -3 - 1)

Evaluate the difference

End = (1, -4)

Hence, your end position is 1, -4)

1. A certain manufacturing process to build phone batteries results in the production of defective batteries at a rate of 5% (0.

lesya [120]

Answer:

0.5 ; 0.475 ; 0.689 ; 0.4013

Step-by-step explanation:

Given that:

Rate of production of defective batteries p = 0.05

Number of batteries produced (n) = 10

The expected number of defective batteries = mean = n * p = 10 * 0.05 = 0.5 batteries

Variance of defective batteries :

Var(X) = n * p * q ; q = 1 - p

Hence,

Var(X) = 10 * 0.05 * 0.95 = 0.475

Standard deviation (X) = sqrt(variance) = sqrt(0.475) = 0.689

Probability that atleast 1 battery is defective :

Using the binomial probability function

P(x ≥ 1) = 1 - p(x = 0)

= 1 - q^n

= 1 - 0.95^10

= 1 - 0.59873693923837890625

= 0.40126306076162109375

= 0.4013
