Answer:

1.3%

Step-by-step explanation:

Phat = 0.53

1 - phat = 1 - 0.53 = 0.47

Sample size, n = 5913

Assume the confidence level = 95%

Zcritical at 95% = 1.96

Margin of Error = Zcritical * √(phat(1 -phat)) / n

Margin of error :

1.96 * √((0.53 * 0.47) / 5913)

1.96 * 0.0064905

= 0.0127215

= 0.0127215 * 100%

= 1.272%

= 1.3%

Answer:

D: 14q + 21√qr

Step-by-step explanation:

We want to find the product of;

(2√q + 3√r) and 7√q.

Where p and q are integers.

Using distributive property, we have;

(2√q × 7√q) + (3√r × 7√q)

>> 14q + 21√qr

Correct option is D

Answer:

C) (a-12b)(a+12b)

Step-by-step explanation:

a^2-144b^2 = (a-12b)(a+12b)

This is the formula that when two terms squared are written with a minus sign between them their factors are the product of the original numbers once with a plus sign and once with the minus sign.

This can be explained by multiplying them.

                (a-12b)

                *(a+12b)        

                  a²- 12ab

                      +12ab - 144b²      

                    a²    +0    - 144b²    

We see we get the same answer as applying the formula above.

Answer:

Base = 4 units

Height = 8 units

I think the blocks are a unit each and you have to count how much space the triangle is taking up

Answer:

6

Step-by-step explanation:

Remark

This is one of those things that when you see it, you think that really is something.

The trick is to subtract a smaller right triangle from a larger one.

The base for both triangles is 4 (going from where the right angle is to your right where the lines of the red enclosure meet.

Calculations

The height of the larger triangle is 8

The height of the smaller triangle is 5

Area_L = 1/2 8 * 4 = 1/2 * 32 = 16

Area_S = 1/2 5 * 4 = 1/2 * 20 = 10

Red area = 1/2 * 32 - 1/2*20 = 16 - 10 = 6 units

b) 2(6.5)+1=14cm

Answer:

90kg

Step-by-step explanation:

it is so because, to decrease a number by a ratio you have to multiply with the smallest number and divide with the biggest one. For example 117 in the ratio 7:3. 117×3=351 which is divided by 7 and is equal to 50.14.

The value 117kg decreased in the ratio 10:13 will be 90kg

Given the ratio 10:13. To reduce 117kg in this ratio, we will follow the steps:

Step 1: Multiply 117 by the smallest value

117 * 10 = 1170

Step 2: Divide the result by the largest value to have:

Value = 1170/13

Value = 90kg

Hence the value 117kg decreased in the ratio 10:13 will be 90kg

Answer:

c. 172 in^2

I did this!

The surface area of the solid is 176 in².

Surface area is the amount of space covering the outside of a three-dimensional shape.

Given that a solid figure made by joining two cuboids, we need to find the total surface area of the solid,

So, we will find the TSA of lower and upper cuboids and then minus the base area of the upper cuboid as it is a overlapping,

Also, the formula used for TSA of a cuboid = 2(LH + WH + LW)

L = length, W = width and H = height,

So,

TSA = 2(7·3 + 3·5 + 5·7) + 2(4·3 + 3·1 + 4·1) - 1·4

= 2(21 + 15 + 35) + 2(12 + 3 + 4) - 4

= 2 × 71 + 2 × 19 - 4

= 142 + 38 - 4

= 142 + 34

= 176 in²

Hence the surface area of the solid is 176 in².

Answer:

[tex]Volume = 288in^3[/tex]

Step-by-step explanation:

Given

[tex]Base\ Cubes = 36[/tex]

[tex]Layers = 8[/tex]

Required

The volume of the prism

The number of base cubes represents the base area and the number of layers represents the height of the prism.

So, the volume is calculated as:

[tex]Volume = Base\ Cubes * Layers[/tex] i.e Base Area * Heights

[tex]Volume = 36 * 8[/tex]

[tex]Volume = 36in^2 * 8in[/tex]

[tex]Volume = 288in^3[/tex]

Answer: 1 over 20

Step-by-step explanation: If the spinner has 5 parts to it at purple is one of those parts then the spinner has a 1/5 chance of it landing there.

If there are 4 cards and 1 of them are pink then there is a 1/4 chance of picking pink(if done randomly)

So if we mutiply 1/4 and 1/5, we get 1/20

That is how I arrived at my answer of 1 over 20

Answer: v+6*8*2 = 96

v = 6*8 = 48

5.5-2 = 3.5

48*3.5 = 168

168/2 = 84

96+84 = 180

The volume is 180 feet.
