The rounding up of 1.18769843885 to 5 decimal places is 1.18770.

What is the rounding up of numbers in decimal places?

The rounding up of numbers is an estimate that says if a digit is more than 5, that number can be considered as one and added to the next preceding number.

To round up a number in a decimal place, we need to start counting our decimal place after the decimal point.

Here,

we are to round 1.18769843885 to 5 decimal places

So, 1.18769843885 becomes:

If -10x+3y = 9 and -4x+7y =1 are true equations,what would be the value of -6x-4y

Answers

Answer:

8

Step-by-step explanation:

Notice: we do not have to solve for x, and y. All we really have to do is to subtract the two equations.

(-10x + 3y) - (-4x + 7y) = 9 - 1.

Taking off the parentheses, we get:

-10x + 3y + 4x - 7y = 8.

Simplifying, we get:

-6x - 4y = 8.

So, the answer is 8.

Suppose that a is an angle with sin A = 3/7 and a is not in the second quadrant. Compute the exact value of 10 a. You do not have to rationalize the denominator. Please answer it

Answers

Answer:

The exact value of [tex]10\cdot a[/tex] is [tex]253.77^{\circ}[/tex].

Step-by-step explanation:

Sine function is a bounded function between -1 and 1 and positive in the first and second quadrants. From statement we deduct that [tex]a[/tex] is in the first quadrant, that is, [tex]0^{\circ}< A < 90^{\circ}[/tex]. Then, we determine the angle by inverse trigonometric function:

[tex]A = \sin^{-1} \frac{3}{7}[/tex]

[tex]A \approx 25.377^{\circ}[/tex]

Then, the exact value of [tex]10\cdot a[/tex] is [tex]253.77^{\circ}[/tex].

by 8% every year. Which of the following functions models the lion population after x years?

Answers

Step-by-step explanation:

After each year, the new population of the lions is 100% - 8% = 92% of the population of the lions the year before.

Hence our exponential base should be 0.92, indicating exponential decay. (A)

Answer:

after each year the new population of the lions

is 100% - 8% is equals to 92% of the population of the lion year before

Hence our exponential base should be 0.92 (A)

Pls help ASAP PLS PLS PLS

Answers

Answer:

Step-by-step explanation:

Let the exponential function for the given table is,

f(x) = a(b)ˣ

Here, f(x) = Price of the item after 'x' years

a = Initial price of the item

b = Growth factor

x = Duration(years) from year 1913

By exponential regression calculator,

Exponential function represented by the table will be,

f(x) = 7.822(1.034)ˣ

Now we have to calculate the price of the item in year 2025.

Difference in time = 2025 - 1913

                              = 112 years

Price of the item after 112 years,

f(112) = 7.822(1.034)¹¹²

        = $330.840

hi sorry i don’t speak spanish :(

x=5
y=52


since AB and BC are the same length, you know it is an isosceles triangle
so two of the angles are the same
angle A and angle C are the same
so y = 52
A = C :. y = 52


all angles of a triangle add to 180
so add 52 and 52 to get 104
subtract 104 from 180 to get 76
set 14x + 6 = 76
14x = 70
x = 5

Kylie has a bag that contains orange chews, apple chews, and lime chews. She performs an experiment. Kylie randomly removes a chew from the bag, records the result, and returns the chew to the bag. Kylie performs the experiment 46 times. The results are shown below:
A orange chew was selected 5 times.
A apple chew was selected 23 times.
A lime chew was selected 18 times.

Based on these results, express the probability that the next chew Kylie removes from the bag will be a flavor other than lime as a decimal to the nearest hundredth.

Answers

Answer:

The probability is 0.609

Step-by-step explanation:

Out of 46 times that the experiment was performed:

A orange chew was selected 5 times.

A apple chew was selected 23 times.

A lime chew was selected 18 times.

We can find the relative frequency of each one of them as the quotient between the number of times that a particular chew was selected, and the total number of chews.

Then for the orange ones we have a relative frequency (that can be thought as the probability) of:

Po = 5/46

For apple we get:

Pa = 23/46

For Lime we get:

Pl = 18/46

We want to find the probability that the next chew Kylie removes from the bag will be a flavor other than lime (so this is equal to the probability of getting orange plus the probability of getting apple):

P = Po + Pa = 5/46 + 23/46 = 0.609

Answer:

0.61

Step-by-step explanation:

Kylie has a bag that contains orange chews, apple chews, and lime chews. She performs an experiment. Kylie randomly removes a chew from the bag, records the result, and returns the chew to the bag. Kylie performs the experiment 46 times. The results are shown below:

A apple chew was selected 23 times.

A lime chew was selected 18 times.

Based on these results, express the probability that the next chew Kylie removes from the bag will be a flavor other than lime as a decimal to the nearest hundredth.

The experiment occured 46 times, a flavor other than lime was selected 5+23=28 times.

Probability the next chew will be a flavor other than lime:

You flip 15 fair coins once. What is the probability of getting at least 12 heads?

Answers

Answer:

0.017578 or 1.76%

Step-by-step explanation:

The probability of getting at least 12 heads is 0.01757.

What is Binomial Distribution?

In a binomial probability distribution, the number of "Successes" in a series of n experiments is represented as either success/yes/true/one (probability p) or failure/no/false/zero (probability q = 1-  p), depending on the outcome's boolean value.

Given a coin is tossed 15 times,

to find the probability of getting 12 heads,

P(X ≥ 12)  Probability of at least 12 successes

At least 12 successes include X-values of

X=12, 13, 14, 15

To solve this problem, find the sum of the binomial probabilities for each of the values of X, or if there is only one value of X, find the probability of P(X). In this problem,

P(12) + P(13) + P(14) + P(15)

P(X ≥ 12) = P(12) + P(13) + P(14) + P(15)

p(x) = ⁿCₓpˣqⁿ⁻ˣ

n = 15

P(X ≥ 12) = P(12) + P(13) + P(14) + P(15)

P(X ≥ 12) = ¹⁵C₁₂(0.5)¹²(0.5)¹⁵⁻¹² + ¹⁵C₁₃(0.5)¹²(0.5)¹⁵⁻¹³ +  ¹⁵C₁₄(0.5)¹²(0.5)¹⁵⁻¹⁴

                      +  ¹⁵C₁₅(0.5)¹²(0.5)¹⁵⁻¹⁵

P(X ≥ 12) = 0.01388 + 0.00320 + 0.00045  + .0000030

      P(X ≥ 12) = 0.01757

Hence probability is  0.01757.
