Find z such that 4.8% of the standard normal curve lies to the left of z. (Round your answer to two decimal places)

lukranit [14]

Answer:

The correct answer will be "-1.66".

Step-by-step explanation:

Let z₀ be,

$P(z$

$=0.048$

⇒ $\Phi (z_0)=0.048$

Now,

⇒ $\Phi (-1.6646)=0.048$

$z_0=-1.6646$

$\simeq -1.66$

Thus the above is the right answer.

What is 1/2(x+14) because i am having trouble solving it and no calculator has been able to help me also.

ivann1987 [24]

Hi there!

»»————-　★　————-««

I believe your answer is:

$\frac{1}{2}x+7$

»»————-　★　————-««

Here’s why:

⸻⸻⸻⸻

$\boxed{\text{Simplifying the equation...}}\\\\\frac{1}{2}(x+14)\\------------\\\rightarrow \frac{1}{2}*x = \frac{1}{2}x\\\\\rightarrow\frac{1}{2}*14=7\\\\\rightarrow \frac{1}{2}(x+14)= \boxed{\frac{1}{2}x+7}$

⸻⸻⸻⸻

Hope this helps you. I apologize if it’s incorrect.

for small changes in temperature, the formula for the expansion of a metal rod under a change in temperature is: g-l=al(t-t), wh

Anuta_ua [19.1K]

Equation giving the length of this rod at temperature is g = 0.000085t + 84.991075 cm.

What is temperature ?

A temperature is a unit used to represent voguishness or coolness on any of a number of scales, including Fahrenheit and Celsius.
According to temperature, heat energy will naturally move from a hotter( body with an advanced temperature) to a colder( body with a lower temperature)( one at a lower temperature).

Given that,

Temperature denoted by T

G - L = aL(t - T)

G = aLt + L(1 - aT)

Slope = aL

Intercept = L(1 - aT)

g = 0.000085t + 84.991075 cm
