Step-by-step explanation:

Remark

The ratios are certainly correct but that doesn't mean that they show similarity. SSA is a very dangerous proposition to use. Redraw triangle DEF of that DF is going to upwards to your right hand side. Make E as it was before. Why isn't this right?

It isn't right because E has gone from being an acute angle to an obtuse angle (an angle larger than 90 but less than 180).

The ratios are still true, but the angles do not match. So the whole answer is incorrect.

Answer:

2n +14 = 30 I can use inverse operations and solve for n.

Step-by-step explanation:

twice means 2 so twice a number,n, means 2 times n thus 2n.

sum means add  so, 2n + 14

is means equal so 2n + 14 = 30

If you solve it you will find n = 8

Answer:

area = 432 ft²

Step-by-step explanation:

area = 1/2(B1 + B2)(H)

area = 1/2(20 + 16)(24) = 432 ft²

I just did the test

The range and domain of the function exists on all real values

Domain of a function is the value of the input of graph for which the function exists.

The range of a function is the value of the output of graph for which the function exists.

The given graph denotes an exponential function showing the arrow pointing infinitely in both directions. Hence the range and domain of the function exists on all real values

Answer:

No ;

Step-by-step explanation:

Given ;

s2 = 10 ; n2 = 10 ; s1 = 12 ; n1 = 12

Hypothesis :

H0 : σ1² = σ2²

H1 : σ1² ≠ σ2²

The test statistic :

Ftest = s1² / s2² = 12² / 10² = 144 / 100 = 1.44

The Pvalue using the Pvalue from Ftest calculator :

Numerator df = 12 - 1 = 11

Denominator df = 10 - 1 = 9

Pvalue = 0.2969

At α = 0.1

If Pvalue > α ; Fail to reject H0

0.2969 > 0.1 ; Hence, we fail to reject the Null

Hence, we cannot conclude that variation exists

Answer:

Number of cookies sold is 2000 and number of cupcakes sold is 1500

Step-by-step explanation:

Let number of cookies be [tex]x[/tex]

and number of cupcakes be [tex]y[/tex] so

[tex]x+y=3500[/tex]

Cost of one cookie is $0.75

Cost of one cupcake is $2

[tex]0.75x+2y=4500[/tex]

[tex]x+y=3500[/tex] [tex]\times 2[/tex]

[tex]2x+2y=7000[/tex]

[tex]-1.25x=-2500\\\Rightarrow x=\dfrac{2500}{1.25}\\\Rightarrow x=2000[/tex]

[tex]y=3500-x=3500-2000\\\Rightarrow y=1500[/tex]

Number of cookies sold is 2000 and number of cupcakes sold is 1500.

Answer:

-20 feet

Step-by-step explanation:

change in depth = number of feet below the surface + number of depth on the surface

Because the submarine is below surface, a value of -30 would be given

-30 + 10 = -20 feet

Complete question :

The line plot shows the weights of packages of meat that members of a club bought. The meat will be mixed with vegetables to make stew for a club dinner. Each serving of the stew contains 1/4 pound of meat. How many servings of the stew can the club make?

Answer:

36 servings

Step-by-step explanation:

From the plot ; we take the sum of total weight of meat packages :

(5/8 * 2) + 6/8 + 1 + (9/8 * 3) + 10/8 + 11/8

10/8 + 6/8 + 8/8 + 27/8 + 10/8 + 11/8 = 72 / 8 = 9 meat packages

Each serving of meat = 1/4

Number of servings the club can make :

Total meat package / pound of meat per serving

(9 ÷ 1/4)

9 * 4/1

= 36 servings

Answer:

36 hope this help

Answer: 17/19

Step-by-step explanation:

Number of red rocks = 6

Number of orange rock = 1

Number of blue rocks = 4

Number of white rock = 1

Number of yellow rocks = 7

Total number of rocks = 19

Probability of not getting a orange the first time will be (1 - 1/19) = 18/19.

Probability of not getting an orange the second time will be: (1 - 1/18) = 17/18

Probability of not getting an orange on both occasion will be:

= 18/19 × 17/18

= 17/19

Answer:

x = 95°

y = 147°

z = 128°

Step-by-step explanation:

z = 180 - 52 = 128°

x: first find the remaining angle in the big triangle, 180 - (45 + 50) = 85°

x = 180 - 85 = 95°

y: first find the remaining angle in the small triangle, 180 - (95 + 52) = 33°

y = 180 - 33 = 147°

Answer:

x = 8.17

Step-by-step explanation:

We will be using pythagoras theorem:

[tex]a^{2} + b^{2} = c^{2}[/tex]

=> [tex]4.25^{2} + x^{2} = 9.21^{2}[/tex]

=> [tex]x^{2}[/tex] = 84.8241 - 18.0625 = 66.7616

=> x = [tex]\sqrt{66.7616}[/tex] = 8.17077719.. = 8.17 (3 s.f)

Answer:

1) The function is decreasing exponentially at a rate of 15% every decade.

2) The function is increasing exponentially at a rate of 20% every year.

Step-by-step explanation:

1) 1–0.85 = 0.15

0.15 x 100 = 15%

2) 1.2–1 = 0.2

0.2 x 100 = 20%

Answer:

There are 30240 possible codes.

Step-by-step explanation:

For the first digit, there are 10 number choices possible:

0, 1, 2, 3, 4, 5, 6, 7, 8, 9

For the second digit, 9 number choices, because one of the digits cannot be repeated.

For the third, 8 number choices, because two of the digits cannot be repeated.

For the fourth, 7 number choices, because three of the digits cannot be repeated.

For the fifth, 6 number choices because four of the digits cannot be repeated.

Now multiply all the numbers, and you can see that there are 10*9*8*7*6, or 30240 codes possible.

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

Explanation:

H = heads

T = tails

Something like HHT means we get two heads in a row at first, followed by one tail. The order matters. Since there are 2 sides per coin, and 3 coins, this leads to 2^3 = 8 different possible ways to flip three coins.

Those 8 outcomes are:

Again the order matters.

------------

Now let's define the following events

There's only one way to get three heads, and that's HHH. So P(A) = 1/8.

There are three ways to get exactly two heads. Those three ways are: HHT, HTH, THH. This means P(B) = 3/8.

From those two probabilities, we then know that P(C) = 4/8 = 1/2 since there are 1+3 = 4 ways to get two or more heads, leaving 8-4 = 4 ways to get the other situations.

Now let's define function notation V(A) to mean "the net value of event A occurring". It's the number of points you receive if event A happens. We are given the following info:

From here, multiply the probability values with their corresponding net values

Finally, add up those results to get the expected value: 0.5+0.75+(-0.5) = 0.75

Each time a turn happens, we expect on average to get 0.75 points

Imagine a scenario where you play the game 10,000 times. If you record the result of each turn and then compute the arithmetic mean, you should get somewhere close to 0.75; it likely wont be 0.75 exactly due to the nature of theoretical probability and empirical probability not being perfectly aligned. However, due to the law of large numbers, the two should be very close when you do a large number of trials.

Because we're dealing with averages, it is possible to get a decimal value as the answer even though the point values of events A,B,C are integers.

Answer:

The radius is 20 units.

Step-by-step explanation:

(r)^2 + 21^2 = (r+9)^2

r^2 + 441 = r^2 + 18r + 81

360 - 18r = 0

360 = 18r

20 = r
