Distribute the 34 to both the x and -1, and once you do that, your answer is 34x - 34

Answer:

34x - 34

Step-by-step explanation:

34(x - 1) ← multiply each term in the parenthesis by 34

= 34x - 34

Step-by-step explanation:

The condition that calls be made between 8am and 4pm will exclude anyone who leaves home for work or school during those hours, which are the most common work periods of the day.  The sampling will consist primarily of home-keepers, babysitters, or students skipping class or doing homework, with an occasional worker who works the night shift and is upset with the call since it woke that person from sleep.

I assume you're just solving for x. Factorize the left side as

3 sin²(x) - 3 sin⁴(x) = 3 sin²(x) (1 - sin²(x)) = 0

Recall that

sin²(x) + cos²(x) = 1

so that the equation further reduces to

3 sin²(x) cos²(x) = 0

Also recall the double angle identity,

sin(2x) = 2 sin(x) cos(x)

which lets us rewrite the equation as

3/2² (2 sin(x) cos(x))² = 3/4 sin²(2x) = 0

Solve for x :

3/4 sin²(2x) = 0

sin²(2x) = 0

sin(2x) = 0

2x = arcsin(0) + 2nπ   or   2x = π - arcsin(0) + 2nπ

(where n is any integer)

2x = 2nπ   or   2x = (2n + 1) π

x = nπ   or   x = (2n + 1)/2 π

Notice that this means the solution set is

{…, -2π, -3π/2, -π, -π/2, 0, π/2, π, 3π/2, 3π, …}

so we can condense the solution further to

x = nπ/2

with any integer n.

Answer:

The area of a triangle can be determined with the two side lengths, the length and breadth/width multiplied.

x = unknown value of breadth/width

23 = length

506 = the area of the two lengths multiplied

23(x) = 506

/23        /23

x = 22, 22 metres is it's breadth.

Answer:

22m is the breadth of the rectangle.

Step-by-step explanation:

To Find:

Solution:

As, we know,

[tex]{ \boxed{ \pink{Area _{(rectangle)} \: = length \times breadth}}}[/tex]

➝ 506m² = l × b

➝ 506m² = 23 × b

➝ b = 506/23 = 22

Hence, Breadth of the Rectangle is 22m.

Area = length × breadth

Answer:

2; 3; 10

Step-by-step explanation:

1.) There are 4 halves (1/2) in 2; 4/2 = 2

2.) There are 15 1 fifths (1/5) in 3; 15/5 = 3

3.) There are 10 1 eights (1/8) in 1 and 1 fourth; 1.25/0.125 = 10

The z-score of the considered newborn having 4,000 g weight is [tex]\dfrac{4000 - \mu}{\sigma}[/tex]

If we've got a normal distribution, then we can convert it to standard normal distribution and its values will give us the z score.

If we have

[tex]X \sim N(\mu, \sigma)[/tex]

(X is following normal distribution with mean [tex]\mu[/tex] and standard deviation  [tex]\sigma[/tex])

then it can be converted to standard normal distribution as

[tex]Z = \dfrac{X - \mu}{\sigma}, \\\\Z \sim N(0,1)[/tex]

(Know the fact that in continuous distribution, probability of a single point is 0, so we can write

[tex]P(Z \leq z) = P(Z < z) )[/tex]

Also, know that if we look for Z = z in z tables, the p value we get is

[tex]P(Z \leq z) = \rm p \: value[/tex]

For the considered case, the statement in the problem is missing the mean weight of the newborn and standard deviation of the data set of weights of newborn.

Thus, for them, we can consider variables in place of their actual values.

Let we have:

Then, the z-score for X = 4000 is

[tex]z = \dfrac{x - \mu}{\sigma} = \dfrac{4000 - \mu}{\sigma}[/tex]

Thus, the z-score of the considered newborn having 4,000 g weight is [tex]\dfrac{4000 - \mu}{\sigma}[/tex]

Answer:

y = 500(1.10)^4

Step-by-step explanation:

We put the 1 in 1.10 instead of 0.10, because we're trying to find 10% of $500, added to the $500 itself. 1 is the same as 100%. 100% here is $500. So by doing 1.10, we're finding 110% or $500 + 10% of $500.

Step-by-step explanation:

     To answer your question of "I mainly need help with knowing what to do with y=-1​" you will graph it as you do with y = - [tex]\frac{5}{2}[/tex]x + 4.

     Any y = something equation will be a horizontal line. There is no slope, the "mx" chunk, so the line stays straight. You will put a dot at (0, -1) and draw a line straight from that point.

     For y = - [tex]\frac{5}{2}[/tex]x + 4, place a dot at (0, 4) and then count down 5 units and 2 units to the right to place another dot. Then draw a line through these two dots and extend it beyond to create the line.

For WXYZ to be a parallelogram, the value of x must be 3.

A parallelogram is a quadrilateral in which opposite sides are parallel and equal to each other. Opposite angles are also equal to each other. In a parallelogram, diagonals bisect each other when they intersect each other.

In a parallelogram when diagonals intersect, they bisect each other.

So, WC and CY will be equal to each other

i.e. WC = CY

i.e. [tex]2x+5 = 3x+2[/tex]

[tex]2x-3x = 2-5[/tex]

[tex]-x=-3[/tex]

[tex]x=3[/tex]

Therefore, For WXYZ to be a parallelogram, the value of x must be 3.

Answer:

x = ± 5

Step-by-step explanation:

for the figure to be an isosceles trapezoid

then the lower base angles must be congruent , that is

3x² - 4 = 2x² + 21 ( subtract 2x² from both sides )

x² - 4 = 21 ( add 4 to both sides )

x² = 25 ( take square root of both sides )

x = ± [tex]\sqrt{25}[/tex] = ± 5

Answer:

x=5

The margin of error for the population mean for the 90% confidence level is 1.10.

The margin of error is a statistic that expresses how much random sampling error there is in a survey's results. The wider the margin of error, the less confident one should be that a poll result reflects the outcome of a population-wide survey.

It is given by the formula:

[tex]\text{MOE}_{\gamma}=z_{\gamma} \times \sqrt{\frac{\sigma^{2}}{n}}[/tex]

As the mean is given to us is 71 beats and the standard deviation is 6 beats, therefore, the margin of error for 90% confidence level can be written as,

[tex]\text{MOE}_{\gamma}=z_{\gamma} \times \sqrt{\frac{\sigma^{2}}{n}}\\\\\text{MOE}_{\gamma}=1.645 \times \sqrt{\dfrac{6^{2}}{80}}\\\\\text{MOE}_{\gamma}=1.645 \times \sqrt{\dfrac{36}{80}}\\\\\text{MOE}_{\gamma}=1.1034\approx 1.10[/tex]

Hence, the margin of error for the population mean for the 90% confidence level is 1.10.

Step-by-step explanation:

Domain tells us all the possible x values or inputs of a function.

Here the input is n.

The domain here is defined on the interval [-1,3) so the domain can be notated in 3 ways.

Interval Notation: [-1,3]

Words: All inputs that is between -1 and 3, exclusively.

Sign Notation:

The Range of a function is possible y values or outputs of a function.

For the range, plug in x values to find the y values.

Since the range in this problem, is only defined for -1 to 3. Plug in -1 for n in the function.

[tex]2( - 1) - 1 = - 3[/tex]
