PLEASE HELP! (WILL GIVE BRAINLIEST FOR RIGHT ANSWER)

Mathematics
1 answer:
dimaraw [331]3 years ago

Answer:

-41.29*  10^-7

Step-by-step explanation:

You would change the order of the numbers by multiplying -4.44 and 9.3 together and multiply 10^-7 and 10^0. Which would now look like this:

(-4.44* 9.3)* (10^-7* 10^0)

-4.44* 9.3= -41.292 and 10^-7* 10^0= 1* 10^-7. So now the equation would look like this:

-41.292* 10^-7

Then round -41.292 to 2 decimal places which would be -41.29.

-41.29*  10^-7

That's the answer. I hope this helps!

diamong [38]

Answer:

Step-by-step explanation:

From the missing information;

Lets assume that;

\text{the exponential distribution mean = 500 thousand naira}

\text{Range 100 thousand} → \text{1 million naira}

∴

a)

X \sim exp (\dfrac{1}{500}) \\ \\  P( X \le x) = 1 - e^{\dfrac{-x}{500}} \\ \\ P(X < 700) = 1 - e^{\frac{-7}{5}} \\ \\  \mathbf{P(X< 700) = 0.75340}

b)

Y \sim \cup (100,1000) \implies P(Y \le y ) = \dfrac{y - 100}{1000-100} \\ \\ P(Y < 700) = \dfrac{600}{900} = 0.67

c)

P(X < 830)= 1 - e^{\frac{-830}{500}} \\ \\ P(X < 830)= 1 - 0.1901 \\ \\ P(X < 830)=0.8099 \\ \\  P(Y < 830) = \dfrac{730}{900} = 0.8111 \\ \\ Thus;\mathbf{ P(X < 0.8099) = P(Y< 0.8111)}

What is perimeter of the semi circle?
Nesterboy [21]

Answer:

54.22 mm

Step-by-step explanation:

Find the circumference of the circle and then divide it by 2.

We start with the formula for the circumference for the circle:

C = 2πr

To find r, divide 22 by 2:

22/2=11

Now find the cicumference:

C = 2πr = 2(3.14)(11) = 108.46 mm

NOW, to find the perimeter of the semicircle, divide the circumference by 2:

108.46/2 = 54.22 mm

The surface area of a cube is represented by the expression below, where s is the side length of the cube. Find the surface area
Dmitry [639]

Answer:

486 centimeters³

Step-by-step explanation:

Surface area of a cube = 6s²

Where,

s = side length

Find the surface area of a cube-shaped jewelry gift box with a side length of 9 centimeters.

s = 9 centimeters

Surface area of a cube = 6s²

= 6 × 9²

= 6 × 81

= 486 centimeters³

Surface area of a cube-shaped jewelry gift box with a side length of 9 centimeters 486 centimeters³
