What is the value of Z in the equation to Z +7 equals -5

tangare [24]

Answer:

-12

Step-by-step explanation:

The Equation:

z + 7 = -5

Solve for the variable, z by isolating it. Note the equal sign, what you do to one side, you do to the other.

Note the rule PEMDAS.

PEMDAS is the order of operation & =

Parenthesis

Exponents (& roots)

Multiplication

Division

Addition

Subtraction

Isolate the variable. To do so, subtract 7 from both sides:

z + 7 = -5

z + 7 (-7) = -5 (-7)

z = -5 - 7

Simplify:

z = -5 - 7

z = -12

-12 is your value for z.

Find the probability

zalisa [80]

Answer:

33.3333%

Step-by-step explanation:

each side would be 50% and if one side is split between three it would equal if it was 16.6667 each

since tehre are two red sides multiply 16.6667 by 2 and u get 33.3333%

Noise levels at 3 airports were measured in decibels yielding the following data:

Shalnov [3]

Answer:

a) The 90% confidence interval for the mean noise level at such locations

(112.46 , 163.54)

b) The critical value that should be used in constructing the confidence interval

Z₀.₁₀ = 1.645

Step-by-step explanation:

Step(i) :-

Noise levels at 3 airports were measured in decibels yielding the following data

108 146 160

Mean of given data

$x^{-} = \frac{108+146+160}{3} = 138$

x : 108 146 160

x-x⁻ : -30 8 22

(x-x⁻ )² : 900 64 484

Variance σ ² = ∑(x-x⁻ )²/ n-1

= $\frac{900+64+484}{3-1}= 724$

Standard deviation

σ = √724 = 26.90

Step(ii):-

The 90% confidence interval for the mean noise level at such locations

$(x^{-} - Z_{0.90} \frac{S.D}{\sqrt{n} } , (x^{-} + Z_{0.90} \frac{S.D}{\sqrt{n} } )$

The critical value that should be used in constructing the confidence interval

Z₀.₁₀ = 1.645

$(138 - 1.645 \frac{26.90}{\sqrt{3} } , (138 + 1.645 \frac{26.90}{\sqrt{3} } )$

( 138 - 25.54 , 138 + 25.54 )

(112.46 , 163.54)
