The figure shows the elliptical orbit of Mercury, whose minimum distance to the Sun is 29 million miles and whose maximum distan

ce to the Sun is 43 million miles. According to Kepler's laws, the average distance of a planet to the Sun is equal to half the length of the orbit's major axis. The average distance of Mercury to the Sun is _____ million miles. (Enter only the number.)

The minimum distance between Mercury and the sun is 29 million miles.
The maximum distance between Mercury and the sun is 43 million miles.
Therefore, the length of the orbit's major axis is
29 + 43 = 72 million miles
and the average distance is
72/2 = 36 million miles

What is the value of b in the equation (y)*
KonstantinChe [14]

Answer:

b = -6

Step-by-step explanation:

Apply the exponent rule that   \frac{1}{x^{n}} = x^{-n}

In this case, \frac{1}{y^{24}}  = y^{-24}

Set that equal to (y^{b})^{4}:

(y^{b})^{4} = y^{-24}

Apply the exponent rule that (x^{m})^{n} = x^{mn} so now you get:

y^{4b} = y^{-24}

Since the base is y for both sides of the equation, just set the exponents equal to each other and solve for b.

4b = -24

divide each side by 4 to get:

b = -6

Steel rods are manufactured with a mean length of 29 centimeter (cm). Because of variability in the manufacturing process, the l
zavuch27 [327]

Solution :

Given data :

The mean length of the steel rod = 29 centimeter (cm)

The standard deviation of a normally distributed lengths of rods = 0.07 centimeter (cm)

a). We are required to find the proportion of rod that have a length of less than 28.9 centimeter (cm).

Therefore, P(x < 28.9) = P(z < (28.9-29) / 0.07)

                                    = P(z < -1.42)

                                   = 0.0778

b). Any rods which is shorter than 24.84 cm or longer than 25.16 cm that re discarded.

Therefore,

P (x < 24.84 or 25.16 < x) = P( -59.42 < z or -54.85)

                                         = 1.052

Solve for x please help
Fed [463]

Answer:

x = 5

Step-by-step explanation:

By remote exterior angle theorem:

(6 + 25x) \degree = (18x - 3)\degree  + 44\degree  \\ 6 + 25x = 18x - 3 + 44 \\ 25x - 18x = 41 - 6 \\ 7x = 35 \\ x =  \frac{35}{7}  \\ \huge \red{ \boxed{ x = 5}}
