Whats the percent of 1 11/16 ???

shusha [124]

You would need to use a calculator.

1 11/16 = 27/16 = 1.6875

Now multiply 100 to it to make it a percentage:

1.6875 x 100 = 168.75

So your answer is 168.75 %

Answer:

The value of x will be:

$x=-5$

Step-by-step explanation:

Given the equation

$4-2(x+7)=3(x+5)$

Multiply (or distribute) each term in parenthesis on L.H.S by -2, and multiply (or distribute) each term in parenthesis on R.H.S by 3.

$4-2x-14=3x+15$

simplifying the equation by subtracting 14 from the L.H.S

$-10-2x=3x+15$

Subtracting 15 from both sides

$-10-2x-15=3x+15-15$

$-25-2x=3x$

combining the like terms

$-25=3x+2x$

$-25=5x$

dividing both sides of the equation by 5

$\frac{-25}{5}\:=\:\frac{5x}{5}$

$-5=x$

Therefore, the value of x will be:

$x=-5$

Mila [183]

Answer:

The calculated value Z=1.2413 < 1.96 at 0.05 level of significance

Null hypothesis is accepted

An instructor in the English department at CBC believes rates at CBC may be equal to the state average

Step-by-step explanation:

Step(i):-

Given Population proportion

P=68%= 0.68

Sample proportion

$p^{-} =\frac{x}{n} = \frac{179}{250} = 0.716$

Null hypothesis : H₀ : p = 0.68

Alternative Hypothesis :H₁ : p > 0.68

Step(ii):-

Test statistic

$Z = \frac{p^{-}-P }{\sqrt{\frac{P Q}{n} } }$

$Z = \frac{0.716-0.68 }{\sqrt{\frac{0.68 X 0.32}{250} } }$

Z = 1.2413

Level of significance

$Z_{0.05} = 1.96$

The calculated value Z=1.2413 < 1.96 at 0.05 level of significance

Null hypothesis is accepted

An instructor in the English department at CBC believes rates at CBC may be equal to the state average

laboratory tests show that the lives of light bulbs are normally distributed with a mean of 750 hours and a standard deviation o

Angelina_Jolie [31]

Answer:

0.13591

Step-by-step explanation:

What we do here is find a score of both values;

Mathematically;

z-score = (x - mean)/SD

for 825, we have (825-750)/75 = 1

For 900, we have (900-750)/75 = 150/75 = 2

So the probability we want to find is;

P(1<x<2) = P(x<2) - P(x<1)

We use the standard table for this and we arrive at;

P(1<x<2) = 0.13591
