can you answer this 3 question pls giving a fat brainless. :) plss help​

Answer:

16 square inches

Step-by-step explanation:

Given

Triangle (4)

[tex]Height = 3[/tex]

[tex]Base = 2[/tex]

Square (1)

[tex]Length = 2[/tex]

Required

The surface area of the star

This is calculated as the area of the square added to the area of the 4 triangles.

The area of the square is:

[tex]Area =Length^2[/tex]

[tex]A_1= 2^2[/tex]

[tex]A_1= 4[/tex]

[tex]The\ area\ of\ 1[/tex] of the triangles is:

[tex]Area = 0.5 * Base * Height[/tex]

[tex]A_2 = 0.5* 3 * 2[/tex]

[tex]A_2 = 3[/tex]

For the 4 triangle, the area is 4 * A2

So, the total area is:

[tex]Total = A_1 + 4 * A_2[/tex]

[tex]Total = 4 + 4 * 3[/tex]

[tex]Total = 4 +12[/tex]

[tex]Total = 16[/tex]

Answer:

We accept H₀. The information is not enough to reject H₀

Step-by-step explanation:

In 2011

Mean for the cost of a private room in a nursing home    μ = 239  $/day

Sample in 2021

265  283 266 366 243  334  213  266 140 276 292

average  =  x  = 267,64

Standard deviation  s  = 56,31

We assume a normal distribution. Random sample,  sample size and the fact that population standard deviation is unknown drive to develop a           t -student two-tail test at 5 % of significance level

n = 11    then degree of freedom   df  =  n  -  1    df  = 10

Then from t-student table df = 10 and α = 0,05   α/2 = 0,025

we get t(c) =  2,228

Hypothesis Test:

Null Hypothesis                       H₀         x  =  μ  = 239

Alternative Hypothesis           Hₐ         x  ≠  μ

To calculate  t(s)

t(s)  =  (  x  -  μ ) / s/ √n

t(s)  =  ( 267,64  - 239 ) / 56,31/√10

t(s) =  28,64 *3,16 / 56,31

t(s) = 1,61

Comparing   t(s)  and t(c)

t(s) < t(c)

Then t(s) is in the acceptance region we accept H₀ . We did´t found enough evidence to reject H₀

Answer:

c

Step-by-step explanation:

the probability isn't unavailable so it's not A. 0

and it isn't less than 0 because it is still "may occur"

and it is not one because it is still "unlikely"

so its C. close to 0

Answer:

C

Step-by-step explanation:

Close to 0 means there isn't a certain number, and there also isn't a certain answer for what the probability. While all of the others are alreaady stated, this is the only one that is not.

a = zoo

b = carnival

total amount:

15 x 3 = 45

15 x 3 = 45 + 10 = 55

45:55

5 people:

15 x 5 = 75

15 x 3 = 75 + 10 = 85

Answer:

86 meters was back on valentina,

The distance is 126.67 meters that Chloe walked to get back to Valentina.

A right-angled triangle is a triangle, that has one of its interior angles equal to 90 degrees or any angle is a right angle.

Given that,

Valentina and Chloe are standing next to each other.

The distance travelled by Chloe in south direction = 86 meters.

And distance covered in west direction = 93 meters

Since, Valentina does not move from its place.

To find the nearest distance that Chloe come back to Valentina,

Use Pythagoreans theorem,

(Hypotenuse)² = (Base)² +  (Perpendicular)²

Let the required distance is x meters

(x)² = (86)² + (93)²

x² = 7396 + 8649

x² = 16045

x = 126.67

The required distance IS 126.67 meters.

Answer:

10

Step-by-step explanation:

Answer:

4√2 = 5.657

9 - 5.657 = 3.343

√3.343 = 1.828

2√2 = 2.828

1.828 - 2.828 = -1

Answer:

I also got -1 doing it on my calculator

Step-by-step explanation:

i first converted it to exponent form to get rid of the radical

      (9 - 4(2)^1/2 )^1/2  - 2(2)^1/2            solve inside the first parenthsis

      (9 - 4(1.414)^1/2  - 2(2)^1/2              

      (9 - 5.656)^1/2  - 2(2)^1/2                √2 times 4

      (3.343)^1/2  - 2(2)^1/2                     9 - √2 times 4

      1.828  - 2(2)^1/2                             √(9 - √2 times 4)

      1.828  - 2(1.414)                     √(9 - √2 times 4) - 2√2

Answer:

[tex]y = 7.5[/tex]

Step-by-step explanation:

Given

Direct variation implies that:

[tex]y = kx[/tex]

Where k is the constant of variation.

[tex]x=4; y=3[/tex]

Required

Find y when [tex]x = 10[/tex]

[tex]y = kx[/tex]

Make k the subject

[tex]k = \frac{y}{x}[/tex]

For: [tex]x=4; y=3[/tex]

[tex]k = \frac{3}{4}[/tex]

For: [tex]x = 10[/tex]

[tex]k = \frac{y}{x}[/tex] becomes

[tex]k = \frac{y}{10}[/tex]

Substitute [tex]k = \frac{3}{4}[/tex]

[tex]\frac{3}{4} = \frac{y}{10}[/tex]

Make y the subject

[tex]y = \frac{3}{4} * 10[/tex]

[tex]y = \frac{3* 10}{4}[/tex]

[tex]y = \frac{30}{4}[/tex]

[tex]y = 7.5[/tex]
