PLS I DONT HAVE MUCH TIMEEE!!

Answer:

x = 1.5

Step-by-step explanation:

4x + 17 = 23

     -17    -17

4x = 6

Divide both sides by 4.

1.5 = x

Hope that helps and have a great day!

Answer:

x=3/2

Step-by-step explanation:

Subtract 17 on both sides, then divide by 4. You get 3/2 or 1 and 1/2!

hope this helped !!

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

Explanation:

The last term is 9 and the middle coefficient is -6.

We need to find two numbers that multiply to the last term, and also add to the middle coefficient.

Through trial and error, you should find the two numbers -3 and -3

-3 plus -3 = -6

-3 times -3 = 9

Those two values directly lead to the factorization (x-3)(x-3)

We can FOIL out (x-3)(x-3) to get x^2-6x+9 to help confirm the answer. Distribution works as well. The box method is a visual way to do it also.

Hello,

This is a parabola.

The vertex is for x= 15/2*5=3/2, and then the maximum is reached for

[tex]h(3/2)=-5(9/4)+15(3/2)+10=\dfrac{-45+90+40}{4}=\dfrac{85}{4}[/tex]

As 85/4 < 24 the ball does not reach a height of 24 m

thanks

The ball does not reach a height of 24 m.

Any point on a parabola is at an equal distance from both the focus, a fixed point, and the directrix, a fixed straight line. A parabola is a U-shaped plane curve. The topic of conic sections includes parabola, and all of its principles are discussed here.

Given:

The height of the toy cannon all launched is expressed as

h(t)=-5t²+15t+10

a) As, the given equation forms a parabola, the vertex is

t = 15/2 x 5

t = 3/2

So, it reached the maximum height at 3/2

h(3/2) = -5(9/4)+ 15 (3/2) + 10

h(3/2) = 85/4

So, 85/4 < 24 the ball does not reach a height of 24 m.

Answer:

Step-by-step explanation:

Answer:

144

Step-by-step explanation:

From information available

Margin of error = 4

S = 18.61

ME = Z-alpha/2 x s/√n

Alpha = 1-0.99

= 0.01

Alpha/2 = 0.01/2

= 0.005

Z-alpha/2 =2.576

Putting into the formula we have

4/1 = 2.576 x 18.61/√n

When we cross multiply

We have

√n = (2.576 x 18.61)/4

√n = 11.98484

n = 11.98484²

n = 143.63

n = 144

Trigonometric Identities

Before we prove the given identity, we need to recall:

[tex](a+b+c)^2=a^2+b^2+c^2+2ab+2ac+2bc[/tex]

We have to prove that:

[tex](1+\sin\theta+\cos\theta)^2=2(1+\sin\theta)(1+\cos\theta)[/tex]

Let's expand the square on the left side as indicated in the formula above:

[tex](1+\sin\theta+\cos\theta)^2=1^2+\sin^2\theta+\cos^2\theta+2\sin\theta+2\cos\theta+2\sin\theta\cos\theta[/tex]

Recall the fundamental trigonometric identity:

[tex]\sin^2\theta+\cos^2\theta=1[/tex]

Substituting and operating:

[tex](1+\sin\theta+\cos\theta)^2=2+2\sin\theta+2\cos\theta+2\sin\theta\cos\theta[/tex]

Factoring by 2:

Answer: 0.002429

Step-by-step explanation:

Given that:

Degree of freedom = 6

Value of Chisquare test statistic = 20.32

The P value of the Chisquare distribution with a test statistic of 20.32 and a degree of freedom of 6 can be obtained using a Chisquare p value calculator.

P(20.32, 6), at 0.05 the degree of freedom obtained is :

0.002429

This p value shows that result is significant at p < 0.05.

As the P value obtained is lesser than the significance level.

= 0.002429

Answer:

3

Step-by-step explanation:

slope = rise/run

Start at an easy to read point, such as (0, -2).

Go up 3 and right 1.

That is a rise of 3 and a run of 1.

slope = rise/run = 3/1 = 3

Answer: 3

Answer:

3

Step-by-step explanation:

Count how many points it goes up and then over to cross a square through the corner. In this case it goes up 3 over one. That simplifies to be just 3. Hope that made sense.

Step-by-step explanation:

The answer is 17 because the operation PEMDAS

Answer:

17

Step-by-step explanation:

20/ 4+6x2 can be simplified. First, you can divide 20 by 4 because of the order PEMDAS (Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction) 20 divided by 4 is 5. You can then multiply 6 and 2 which gives you 12. Therefore, your equation is down to 5+12. You can add those two and you get 17 :) Hope this helps!! :D ~Happy Halloween~

Answer:

y=4x+3

Step-by-step explanation:

since its parallel they have the same slope

y=mx+b

Answer:

Step-by-step explanation:

Given the equation of calorie count of food computed by:

C = 3h + 13f + 7p

h is the number of grams of carbohydrate contained in the serving,

f is the number of grams of fat contained in the serving, and;

p is the number of grams of protein contained in the serving

We are to make f the subject of the formula as shown:

C = 3h + 13f + 7p

13f = C-3h-7p

Divide through by 13

13f/13 = (C-3h-7p)/13

f =  (C-3h-7p)/13

Hence the formula for f, the number of grams of fat contained in a serving of food is f =  (C-3h-7p)/13

Answer:

The wait  time is unusual because the probability value obtained is less than 2 standard deviation above the mean

Step-by-step explanation:

From the question we are told that

     The average wait time is  [tex]\mu = 55 \ min[/tex]

     The standard deviation is  [tex]\sigma = 33 \ min[/tex]

Generally the probability of  waiting over 1212 minutes is

     [tex]P(X > 1212) = P(\frac{X - \mu}{ \sigma } > \frac{ 1212 - 55}{ 33} )[/tex]

     [tex]P(X > 1212) = P(\frac{X - \mu}{ \sigma } > \frac{ 1212 - 55}{ 33} )[/tex]

[tex]\frac{X -\mu}{\sigma }  =  Z (The  \ standardized \  value\  of  \ X )[/tex]

So

       [tex]P(X > 1212) = P(Z > 35 )[/tex]

From z table  the probability of  (Z  >  35 ) is  

        [tex]P(Z > 35 ) = 0[/tex]

Hence

    [tex]P(X > 1212) = 0[/tex]

The  time is unusual because the probability value obtained is less than 2 standard deviation above the mean

Answer:

60 outfits

Step-by-step explanation:

5 shirts x 3 pants x 4 shoes = 60 outfits (containing 1 shirt, 1 pant, 1 shoe)

This is pretty difficult to explain, but this is basically how you do it when you want to see how many combinations of something there are for multiple different things. Basically, for each of the 5 shirts, there are 3 different pants, and for each of the pants there are 4 shoes. So each pant has 4 shoes, then multiply that by 3 for the 3 pants for each shirt. After that, multiply by 5 for each shirt in the outfits.

Hi! I believe your answer is 4.4 pounds lost per week. 22 total pounds divided by 5 pounds per week equals 4.4 pounds per week. I hope this helps you! Good luck and have a great day. ❤️✨

Answer:

Step-by-step explanation:

This type of probability is independent i.e the occurrence of one does not affect the other.

Probability = expected outcome/total outcome

For a coin:

The total sample space = {H, T} i.e 2

The probability of tossing a head will be:

P(a head) = 1/2

For a die:

Sample space S = {1, 2, 3, 4, 5, 6}

Total number of sample space n(S) = 6

If a number greater than 5 is rolled, the event outcome will be E = {6}

Pr(S>5) = n(E)/n(S)

Pr(S>5) = 1/6

The probability of tossing a head and then rolling a number greater than 5 is expressed as:

Pr(H and S>5) = Pr(H) * Pr(S>5)

Pr(H and S>5) = 1/2* 1/6

Pr(H and S>5) = 1/12

Hence the probability of tossing a head and then rolling a number greater than 5 is 1/12
