katie can build three staircases to make 36 obstacles against the other player. how many staircases will she need to make 24 obstacles?

Answer:

Flipping three coins: Each coin has 2 equally likely outcomes, so the sample space is 2 • 2 • 2 or 8 equally likely outcomes. Rolling a six-sided die and flipping a coin: The sample space is 6 • 2 or 12 equally likely outcomes.

Answer:

6x + 3

Step-by-step explanation:

Given p(x) = 2x - 5 and r(x) = 3x + 4,

p(r(x)) = p(3x+4)

p(3x+4) = 2(3x+4) - 5

p(3x+4) = 6x + 8 - 5

p(3x+4) = 6x +3

Hence the composite function (pr)(x) is 6x + 3

With f(x) is an exponential function, the value of function f(0.5) is 0.88.

Given that, f(-0.5)=27 and f(1.5)=21.

We know that, general form of exponential function, [tex]f(x)=ab^x[/tex].

Here,

[tex]f(-0.5)=ab^{-0.5}[/tex]

[tex]ab^{-0.5}=27[/tex] -----(i)

Now,

[tex]f(1.5)=ab^{1.5}[/tex]

[tex]ab^{1.5}=21[/tex] -----(ii)

From the equation (i) and (ii), we get

[tex]\frac{ab^{1.5}}{ab^{-0.5}}=\frac{21}{27}[/tex]

[tex]ab^2=0.7778[/tex]

[tex]ab=\sqrt{0.7778}[/tex]

[tex]ab=0.8819[/tex]

Now, [tex]f(0.5)=(0.7778)^{0.5}[/tex]

f(0.5)=0.8819

f(0.5)≈0.88

Therefore, the value of function f(0.5) is 0.88.

Answer:

0.1425 = 14.25% probability that the individual's pressure will be between 119.4 and 121.4mmHg.

Step-by-step explanation:

When the distribution is normal, we use the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this question, we have that:

[tex]\mu = 120, \sigma = 5.6[/tex]

Find the probability that the individual's pressure will be between 119.4 and 121.4mmHg

This is the pvalue of Z when X = 121.4 subtracted by the pvalue of Z when X = 119.4. So

X = 121.4

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{121.4 - 120}{5.6}[/tex]

[tex]Z = 0.25[/tex]

[tex]Z = 0.25[/tex] has a pvalue of 0.5987

X = 119.4

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{119.4 - 120}{5.6}[/tex]

[tex]Z = -0.11[/tex]

[tex]Z = -0.11[/tex] has a pvalue of 0.4562

0.5987 - 0.4562 = 0.1425

0.1425 = 14.25% probability that the individual's pressure will be between 119.4 and 121.4mmHg.

The solution to the equation will be:

[tex]x=\sqrt[3]{2},\:x=-\sqrt[3]{2}[/tex]

or

[tex]x = 1.26[/tex] , [tex]x = -1.26[/tex]

Step-by-step explanation:

Given the expression

[tex]\left(3x^2\right)\left(3x^4\right)=36[/tex]

simplify

[tex]9x^6=36[/tex]

Divide both sides by 9

[tex]\frac{9x^6}{9}=\frac{36}{9}[/tex]

[tex]x^6=4[/tex]

[tex]\mathrm{For\:}x^n=f\left(a\right)\mathrm{,\:n\:is\:even,\:the\:solutions\:are\:}x=\sqrt[n]{f\left(a\right)},\:-\sqrt[n]{f\left(a\right)}[/tex]

[tex]x=\sqrt[6]{4},\:x=-\sqrt[6]{4}[/tex]

solving

[tex]x=\sqrt[6]{4}[/tex]

  [tex]=\sqrt[6]{2^2}[/tex]

Apply exponent rule:   [tex]\left(a^b\right)^c=a^{bc}[/tex]

  [tex]=\sqrt[6]{2^2}=2^{2\cdot \frac{1}{6}}[/tex]

   [tex]=\sqrt[3]{2}[/tex]

   [tex]= 1.26[/tex]

Thus,

[tex]x=\sqrt[3]{2}[/tex]   (or  [tex]x = 1.26[/tex] )

similarly solving

[tex]x=-\sqrt[6]{4}[/tex]

[tex]x=-\sqrt[3]{2}[/tex]  or ([tex]x = -1.26[/tex])

Therefore, the solution to the equation will be:

[tex]x=\sqrt[3]{2},\:x=-\sqrt[3]{2}[/tex]

or

[tex]x = 1.26[/tex] , [tex]x = -1.26[/tex]

Answer:

[tex]3 {x}^{2} \times 3 {x}^{4} = 36 \\ 9 {x}^{6} = 36 \\ {x}^{6} = 4 \\ \boxed{x = \sqrt[6]{4} }[/tex]

Answer:

The distance of two complex numbers

[tex]z_{1} z_{2} = \sqrt{82}[/tex]   = 9.055

Step-by-step explanation:

Step(i):-

Given that z₁ = 6-3i and z₂ = -3-4i

We know that 'z' represents a point on the argand plane with absicca 'x' and ordinate 'y'

Now given points are ( x₁ , y₁)  = (6 ,-3) and (x₂, y₂) = (-3 , -4)

Step(ii):-

The distance of two points

               [tex]\sqrt{(x_{2} -x_{1} )^{2} +(y_{2} - y_{1} )^{2} }[/tex]

     z₁ z₂  [tex]= \sqrt{(-3-6)^{2} +(-4-(-3)^{2} }[/tex]

     [tex]z_{1} z_{2} = \sqrt{81+1}[/tex]

    [tex]z_{1} z_{2} = \sqrt{82}[/tex] =9.055
