Answer:

area = 4cm2

Step-by-step explanation:

the area of triangle is gotten by 1/2bh

1/2 × 2 × 4 = 4.

base is 2cm because it has covered 2 grids while the height is the measure from the base to the tip of the triangle, which is 4cm.

area of square is L × L

2 by 2 = 4.

so, the two shapes have same area.

On a unit test in a statistics class, the teacher determines that the mean test grade was 77.5 with a standard deviation of 5.2.
katovenus [111]

Answer: B. This student's test grade was 2.4 standard deviations above the mean test grade.

====================================================

Explanation:

The z score tells us how far away the raw score is from the mean. This distance is in terms of standard deviations.

  • z = 1 means we're 1 standard deviation above the mean
  • z = 2 means we're 2 standard deviations above the mean

and so on.

Negative z scores indicate the raw score is below the mean.

  • z = -1 means we're 1 standard deviation below the mean
  • z = -2 means we're 2 standard deviations below the mean

and so on. So that's why z = 2.4 indicates the students test grade was 2.4 standard deviations above the mean.

What is the area of the sector with a central angle of 49° and a radius of 11 cm? Use 3.14 for pi and round your final answer to
olga_2 [115]

Answer:

\boxed{\text{51.71 cm}^{2}}

Step-by-step explanation:

If the angle θ is in radians, the formula for the area (A) of a sector of a circle is

A = ½r²θ

If θ is in degrees

A = \dfrac{1}{2}r^{2}\theta \times \dfrac{\pi \text{ rad}}{180^{\circ}}= \pi r^{2}\times\dfrac{\theta }{360}

Data:

θ = 49°

r = 11 cm

Calculation:

\begin{array}{rcl}A& = &3.14\times 11^{2}\times\dfrac{49}{360}\\\\ & = &3.14 \times 121 \times 0.1361\\ & = & \mathbf{51.71}\\\end{array}\\\text{The area of the sector is }\boxed{\textbf{51.71 cm}^{2}}

\text {Mass of earth =} 5.97 \times 10^{24} \text { kg}

\text {Mass of Venus =} 4.87 \times 10^{24} \text { kg}

\text {Difference = }5.97 \times 10^{24}  - 4.87 \times 10^{24}

\text {Difference = }(5.97 - 4.87) \times 10^{24}

\text {Difference = }1.1 \times 10^{24} \text { kg}


--------------- In Pure Text Format --------------
Mass of the earth = 5.97 x 10^{24} 
Mass of Venus = 4.87 x 10^{24}
Difference = (5.97 - 4.87) x 10^{24} = 1.1 x 10^{24} kg

Solve the system algebraically.
disa [49]
No spaces? like t h i s? or    like    thiiiss???  is      this  bugging    you      ????


anyway
use elimination
multiply secn equation by -1
-3x-2y=-6

add to other equation
-3x-2y=-6
<u>4x+2y=10 +</u>
1x+0y=4

x=4
sub back to solve for y

3x+2y=6
3(4)+2y=6
12+2y=6
minus 12 both sides
2y=-6
divide 2
y=-3

(4,-3)
