Rewrite this equation in standard form <br> y+4=-5/2(x

Which best describes the composition of tranformations that maps ∆LMN to ∆L'M'N'. 0,0 is the center of the dilation in each choi

Triangle LMN was dilated by a scale factor of 2 followed by a translation 1 unit right and 3 unit up to form triangle L'M'N'

<h3>What is transformation?</h3>

Transformation is the movement of a point from its initial location to a new location. Types of transformations are<em> reflection, translation, rotation and dilation.</em>

Rigid transformation preserves the shape and size of the figure. <em>Reflection, translation, rotation</em> are rigid transformations.

Trigonometric problems.<br><br> Could someone help me with this? I’m confused.

Oduvanchick [21]

the answer is a) 0.29 bc of SOHCAHTOA if u didn’t learn this then i can see why u were confused but it’s asking for tan which is TOA tan= opposite/adjacent so look for T and find the opposite of that angle which would be 7 and the adjacent would be the number next to it which is 24 so do 7/24 and u get 0.29

Assume that the average life of a refrigerator is 14 years, with the standard deviation given in part (a) before it breaks. Supp

fiasKO [112]

Answer:

The guarantee should be made of $X = 1.555 + 14\sigma$ years, in which $\sigma$ is the standard deviation given in part (a).

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be 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.

Assume that the average life of a refrigerator is 14 years

This means that $\mu = 14$

The standard deviation given in part (a) before it breaks.

This will be the value of $\sigma$

However, the company does not want to replace more than 6% of the refrigerators under guarantee. For how long should the guarantee be made?

We need to find the 100 - 6 = 94th percentile, which is X when Z has a pvalue of 0.94. So X when Z = 1.555. So

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

$1.555 = \frac{X - 14}{\sigma}$

$X = 1.555 + 14\sigma$

The guarantee should be made of $X = 1.555 + 14\sigma$ years, in which $\sigma$ is the standard deviation given in part (a).

The ratio of duck eggs to chicken eggs in an egg store is 2:7.If there are 312 duck eggs in the store.how many chicken eggs are

daser333 [38]

Answer:

x = 1,092

Step-by-step explanation:

Duck eggs : chicken heads =

2 : 7

Number of duck eggs = 312

Number of chicken eggs = x

Duck eggs : chicken heads = 312 : x

Equate both ratios

2 : 7 = 312 : x

2/7 = 312/x

Cross product

2 * x = 7 * 312

2x = 2,184

x = 2,184 / 2

= 1,092

x = 1,092
