Planet B has the larger mass. The mass of planet B is 50 times as large as the mass of planet A.

Mass of planet A = A = 8 * [tex]10^{23}[/tex]

Mass of planet B = B = 4 * [tex]10^{25}[/tex]

[tex]\frac{A}{B}=\frac{8 * 10^{23} }{4*10^{25} }[/tex]

First Dave picks his swimming day, then his running day, and then his biking day. Since each activity is different, the order in which he selects the days matters. Therefore the number of selections is P(7, 3).

Simply put, probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of various outcomes. Statistics is the study of events that follow a probability distribution. The probability is calculated by dividing the total number of possible outcomes by the number of possible ways the event could occur. Probability and odds are two distinct ideas. Odds are calculated by dividing the likelihood of an event by the likelihood that it won't. It is based on the likelihood that something will occur. The justification for probability serves as the main foundation for theoretical probability. For instance, the theoretical chance of getting a head when tossing a coin is 1/2.

Here,

He does 3 activities in 7 days,

P(7,3) is the ways to select the schedule.

Dave chooses his swimming, running, and biking days in that order. The sequence in which he chooses the days is important because each activity is distinct. Consequently, P is the number of choices (7, 3).

What is inverse of function?

What a function's inverse function is F is a function that reverses what F did. The inverse of f is represented by f-1 if it exists and only if f is a bijective function.

Consider, the given function

h(x) = 6x + 8

Let,

The percentage increase in the price of a technology stock is 1.69%.

According to the question,

We have the following information:

The price of a technology stock was $9.45 yesterday. Today, the price rose to $9.61.

We know that following formula is used to find the percentage increase:

Percentage increase = 100*(final price- initial price)/initial price

Percentage increase for the technology stock = 100*(9.61-9.45)/9.45

Percentage increase for the technology stock = 100*0.16/9.45

Percentage increase for the technology stock = 16/9.45

Percentage increase for the technology stock = 1.69%

y-intercepts.

We know lines have various types of equations, the general type is

Ax + By + c = 0, and the equation of a line in slope-intercept form is

y = mx + b.

Where slope = m and b = y-intercept.

the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.

We know lines parallel to each other have the same slope with a different y-intercept.

The scores of geography, economics and science are 38, 76, 80 respectively.

Let Yakubu scored x marks in geography.

Given that the score of him in economics is twice of the score of him in geography.

So, his score in economics = 2x

Again it is given that, the score in science is 4 more than the score in economics.

So the score in science = 2x+4

According to question the combined total score is 194. So the suitable equation is,

x+2x+2x+4 = 194

Solving the equation we get,

5x+4 = 194

5x = 194-4

5x = 190

x = 190/5

x = 38

So the score in geography = 38

the score in economics = 2x = 2*38 = 76

the score in science = 2x+4 = 2*38+4 = 76+4 = 80

Hence the scores of geography, economics and science are 38, 76, 80 respectively.

Using the normal distribution, the probability that the sample proportion of households spending more than $125 a week is less than 0.3 is 30.29%.

Normal distribution refers to a continuous probability distribution wherein values lie in a symmetrical fashion mostly centered around the mean. In a normal distribution, the probability is calculated using the z-score of a measure X. A Z-score refers to a numerical measurement that defines a value's relationship to the mean (of a group of values).

In order to determine the probability of the sample proportion, the z-score of a measure X is determined.

z-score = (X - µ)/σ where µ is the mean and σ is the standard deviation.

The standard deviation σ = √(p(1-p)/n

From the given data:

n = no of random sample = 145

p = probability of success (household spending more than $125) = 0.32

Hence,

σ = √((0.32(1-0.32)/145) = 0.0387

Calculating the z-score when X = 0.3

z-score = (0.3 – 0.32)/0.0387 = -0.516

From the table, the probability of z = -0.516

P(X<z) = 0.30293 or 30.29%

Answer:

x=7

Step-by-step explanation:

Use the Distributive Property to simplify the equation.

The value of x is 7 and the value of y is 37. These values of x and y results in congruence.

For the two triangles, Δ LMN and Δ PQR,

Side LM = Side PQ,

Side LN = Side PR

Side MN = Side QR

⇒ Δ LMN and Δ PQR are congruent by (S.S.S : side side side) property

Since both the triangles are congruent to each other. There corresponding angles will be equal.

i.e. ∠ L = ∠ P, ∠ N = ∠ R and ∠ Q = ∠ M.

⇒ ∠ L = ∠ P

⇒ 3x + 24 = 8x - 11

⇒ 24 + 11 = 8x - 3x

⇒ 5x = 35

⇒ x = 7

In Δ PQR, sum of all angles is 180°

⇒ ∠P + ∠Q + ∠R = 180°

⇒ (8x - 11)° + 84° + ∠R = 180°

⇒ (8×7 - 11)° + 84° + ∠R = 180°

⇒ 45° + 84° + ∠R = 180°

⇒ 129° + ∠R = 180°

⇒ ∠R = 180° - 129° = 51°

We know that ∠N = ∠R

⇒ (2x + y) = 51

⇒ (2×7) + y = 51
