Which angle is vertical to 1?

Answer:

1.72 inches

Step-by-step explanation:

= P=2s×b

= 32.7=2s×9.5

= 32.7=19s

= 32.7/19=19s/19

= s=1.72

Answer:

y = 2/3 x + 7

Step-by-step explanation:

At birth represents the beginning of time for the baby. Lets call this month zero. So here are your coordinates.

x = 0 y = 7 ----> at birth

x = 3 y = 9

x = 6 y = 11

x = 9 y = 13

Now we find the slope between each point. Since the common difference of y is 2 and the common difference in x is 3 , the slope will be

slope = y / x = 2 / 3

Therefore, the equation of the line that represents this relationship is

y = (2/3) x + 7

Answer:

2 inches

Step-by-step explanation:

The radius is simply the distance from the edge if you were at the center, which is equal to half the diameter. So given the diameter is 4 inches, we divide that by two, [tex]\frac{4\text{ inches}}{2}=2\text{ inches}[/tex] and that's our radius!

Answer:

14

Step-by-step explanation:

Para simplificar esta expresión, debemos seguir el orden de las operaciones, también conocido como PEMDAS: paréntesis, exponentes, multiplicación y división (de izquierda a derecha), y suma y resta (de izquierda a derecha).

1. Comience por simplificar la expresión dentro de los paréntesis.

4-2[6-3+4(5-7)]

4-2[6-3+4(-2)]

4-2[6-3-8]

4-2[-5]

4+10 = 14

2. Ahora sustituya el valor simplificado dentro de los paréntesis en la expresión original:

-3+{14}+3

3. Ahora podemos sumar y restar de izquierda a derecha.

-3+14+3 = 14

Entonces, la expresión simplificada es 14.

9.6 KB kilobytes is equal to 0.0096 MB

A unit of measurement is a definite magnitude of a quantity, defined and adopted by convention or by law, that is used as a standard for measurement of the same kind of quantity.

1kB=1000 bytes

1MB=1000 KB

1kB=1/1000MB=0.001 MB

9.6 KB is nothing but 9600 bytes

9.6 KB in MB we have to convert

Now multiply 9.6 with 0.001

9.6×0.001

0.0096 MB

Hence,  9.6 KB kilobytes is equal to 0.0096 MB

Answer:

To find out how many batches of cookies the factory made, we need to divide the total amount of flour used (7 1/2 bags) by the amount of flour used per batch (3 3/4 bags).

We can start by converting 7 1/2 bags of flour to a mixed number: 7 1/2 bags = 7 + 1/2 = 7.5 bags

Next, we can convert 3 3/4 bags of flour to a mixed number: 3 3/4 = 3 + 3/4 = 3.75 bags

Then, we can divide the total amount of flour used by the amount of flour used per batch:

7.5 bags / 3.75 bags/batch = 2 batches

Therefore, the factory made 2 batches of cookies yesterday

Answer:

Step-by-step explanation:

To solve this equation, we can start by using the identity cos(A-B) = cosAcosB + sinAsinB. Substituting A=sin x and B=1, we have:

2cos(sin x - 1) = cos(sin x)cos(1) + sin(sin x)sin(1)

We can then substitute this expression on the left-hand side of the original equation and simplify:

4sinxcosx^2 - 1 = cos(sin x)cos(1) + sin(sin x)sin(1)

Rearranging terms, we have:

4sinxcosx^2 - cos(sin x)cos(1) - sin(sin x)sin(1) = 1

We can now use the identity sin^2x+cos^2x=1 to simplify the left-hand side further:

4sinxcosx^2 - (sin^2x + cos^2x)cos(1) = 1

Simplifying further:

4sinxcosx^2 - (cosx)cos(1) = 1

Now we can divide both sides by cos(1):

4sinxcosx^2/cos(1) - cosx = 1/cos(1)

Rearranging terms:

cosx(4sinxcosx^2/cos(1) - 1) = 1/cos(1)

Finally, we can use the identity cos2x = 2cos^2x - 1 to simplify the left-hand side further:

(2cos^2x - 1)(4sinxcosx^2/cos(1) - 1) = 1/cos(1)

We can then divide both sides by (4sinxcosx^2/cos(1) - 1):

2cos^2x - 1 = 1/cos(1) (4sinxcosx^2/cos(1) - 1)

And finally, we can solve for cosx:

cosx =  1/2 + 1/2cos(1) (4sinxcosx^2/cos(1) - 1)

This is the solution to the equation.

The margin of error for this survey is 8% (0.08*100) rounded to the nearest tenth.

What is the margin of error?

The margin of error is a measure of the precision of a sample estimate. It is used to indicate the degree of uncertainty associated with a sample estimate.

The formula to calculate the margin of error at the 95% confidence level for a sample proportion is:

Margin of error = z* √(p*(1-p)/n)

Where:

z is the z-score for the 95% confidence level (1.96)

p is the sample proportion (36%)

n is the sample size (75)

So the margin of error for this survey would be:

Margin of error = 1.96 * √((0.36 * (1 - 0.36)) / 75)

Margin of error = 0.08

Hence, the margin of error for this survey is 8% (0.08*100) rounded to the nearest tenth.

The triangle on the right side fits into the missing part of the left side.

So what I did is (5+4) and times 10 = 90m.

P.s:If I'm wrong I'm sorry.

Step-by-step explanation:

well, it is a rectangle, where an isoceles right-angled triangle is cut off in the top left corner, but that triangle is added to the top right corner.

so, the area is the same as the regular rectangle.

we know, the area of a rectangle is

length × width

now, we know the length for sure (10 m).

what is the width ?

we know the part of the width until the triangle is 5 m.

and we know the leg length of the triangle is 4 m.

the width is simply the sum of the basic part and the leg length

5 + 4 = 9 m

so the area of all this is

10 × 9 = 90 m²

The firm needs to sample 138.297 products to achieve a ±5% accuracy at a 95% confidence level, given that it believes that the true proportion of defects is no greater than 10%.

Generally, To determine the sample size needed to achieve a ±5% accuracy at a 95% confidence level, with a maximum expected proportion of defects of 10%, you can use the formula for sample size for a proportion. The formula is:

n = (z^2 * p * (1-p)) / E^2

Step-by-step explanation:

Step-by-step explanation:

as always with % calculations :

first find what is 100% or 1%. everything else can be calculated from that.

in our case, we got 100% = 18.

therefore, 1% = 100%/100 = 18/100 = 0.18

how many % are 4 students ?

as many as the times 1% (0.18) fits into 4 :

4 / 0.18 = 22.22222222... %

so,

22.22222222... %
