(Hope this helps can I pls have brainlist (crown)☺️)

Step-by-step explanation:

Percentage form: 104%

Fraction form: $\frac{26}{25}$

Equvulant fraction form: 1.04 = 104/100 = 26/25 = $1\frac{1}{25}$

How to do the problem

Veronika [31]

Ill work it out w/ the steps so you can do it later on. STEP 1) multiply 95 by .10 to get 9.5 STEP 2) subtract 9.5 from 95 to get 85.5, your new price STEP 3) multiply 85.5 by 1.045 *mini step to get 1.045: add 4.5 to 100, get 104.5, divide by 100, get 1.045* then you get $89.35

A manufacturer knows that their items have a normally distributed length, with a mean of 13.1 inches, and standard deviation of

Afina-wow [57]

Answer:

0.73% probability that their mean length is less than 11.1 inches

Step-by-step explanation:

To solve this question, we have to understand the normal probability distribution and the central limit theorem.

Normal probability distribution:

Problems of normally distributed samples are solved using the z-score formula.

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

$Z = \frac{X - \mu}{\sigma}$

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.

Central limit theorem:

The Central Limit Theorem estabilishes that, for a random variable X, with mean $\mu$ and standard deviation $\sigma$ , a large sample size can be approximated to a normal distribution with mean $\mu$ and standard deviation, which is also called standard error $s = \frac{\sigma}{\sqrt{n}}$

In this problem, we have that:

$\mu = 13.1, \sigma = 4.1, n = 25, s = \frac{4.1}{\sqrt{25}} = 0.82$

What is the probability that their mean length is less than 11.1 inches

This is the pvalue of Z when X = 11.1. So

$Z = \frac{X - \mu}{\sigma}$

By the Central Limit Theorem

$Z = \frac{X - \mu}{s}$

$Z = \frac{11.1 - 13.1}{0.82}$

$Z = -2.44$

$Z = -2.44$ has a pvalue of 0.0073.

0.73% probability that their mean length is less than 11.1 inches

Find a comples solution of 2x^2+x+6=0 (if there is more than ine solution separate them with commas)

babunello [35]

Answer:

x = -1/4 + sqrt(47)/4 i , -1/4 - sqrt(47)/4 i

Step-by-step explanation:

2x^2+x+6=0

using the quadratic formula

-b ±sqrt(b^2 -4ac)

--------------------------

-1 ±sqrt(1 -4(2)(6))

--------------------------

2(2)

-1 ±sqrt( 1 - 48)

------------------

-1 ± sqrt(-47)

-------------

-1 ± sqrt(-1) sqrt(47)

-------------------------

remember sqrt(-1) = i

-1 ± i sqrt(47)

----------------

x = -1/4 + sqrt(47)/4 i , -1/4 - sqrt(47)/4 i

Which expression is equivalent to the following complex fraction?

nydimaria [60]

Answer:

$\frac{2y-1}{3y+1}$

Step-by-step explanation:

$\frac{2-\frac{1}{y} }{3+\frac{1}{y} }$ ( multiply numerator and denominator by y to clear the fractions )

$\frac{2-\frac{1}{y} }{3+\frac{1}{y} }$ × $\frac{y}{y}$

= $\frac{2y-1}{3y+1}$

From the figure below, the coordinates for point z are:<br> HELP PLS

Gelneren [198K]

Answer:

(2a, 0)

Step-by-step explanation:

the distance from (a,0) and z from the origin and to each other is both 3. It’s in the middle of two points, there’s an equal distance between w to y and y to z. I hope that makes sense, so, to get the x coordinate multiply a by 2.
