How do I find the value of k

Tju [1.3M]

The value of k is 2/5

<h3>Further explanation</h3>

Vector is quantity that has magnitude and direction.

One example of a vector is acceleration.

Let us now tackle the problem !

$\texttt{ }$

This problem is about Vector Diagram.

$\overrightarrow{OA} = \overrightarrow{a}$

$\overrightarrow{OC} = \overrightarrow{c}$

X is the midpoint of the line AC:

$\overrightarrow{x} = \frac{1}{2} (\overrightarrow{a} + \overrightarrow{c})$

$\texttt{ }$

OC : CD = k : 1

$k \overrightarrow{CD} = \overrightarrow{OC}}$

$k( \overrightarrow{d} - \overrightarrow{c} ) = \overrightarrow{c}}$

$( \overrightarrow{d} - \overrightarrow{c} ) = \frac{1}{k} \overrightarrow{c}}$

$\overrightarrow{d} = \overrightarrow{c} + \frac{1}{k} \overrightarrow{c}}$

$\overrightarrow{d} = ( 1 + \frac{1}{k} ) \overrightarrow{c}}$

$\texttt{ }$

$\overrightarrow{XD} = 3 \overrightarrow{c} - \frac{1}{2} \overrightarrow{a}$

$\overrightarrow{d} - \overrightarrow{x} = 3 \overrightarrow{c} - \frac{1}{2} \overrightarrow{a}$

$( 1 + \frac{1}{k} ) \overrightarrow{c} - \frac{1}{2} (\overrightarrow{a} + \overrightarrow{c}) = 3 \overrightarrow{c} - \frac{1}{2} \overrightarrow{a}$

$( 1 + \frac{1}{k} - \frac{1}{2}) \overrightarrow{c} - \frac{1}{2} \overrightarrow{a} = 3 \overrightarrow{c} - \frac{1}{2} \overrightarrow{a}$

$( \frac{1}{k} + \frac{1}{2}) \overrightarrow{c} - \frac{1}{2} \overrightarrow{a} = 3 \overrightarrow{c} - \frac{1}{2} \overrightarrow{a}$

$\frac{1}{k} + \frac{1}{2} = 3$

$\frac{1}{k} = 3 - \frac{1}{2}$

$\frac{1}{k} = \frac{5}{2}$

$k = \frac{2}{5}$

Each small square in the graph paper represents 1 square unit. Find the area of each figure. Explain your reasoning.

Rashid [163]

Answer:

A. 7.5

B. 10

Step-by-step explanation:

The first one is 3x2 + half of 3x1 for 6 + 0.5*3 total.

The second one is 3x2 + 4 times half a 2x1 for 6 + 4 * 0.5 * 2 = 10

According to survey data, the distribution of arm spans for males is approximately Normal with a mean of 71.4 inches and a stan

Gekata [30.6K]

Answer:

a) 89.97% of men have arm spans between 66 and 76 inches.

b) The z-score for this person's arm span is 5.68. 0% of males have an arm span at least as long as this person

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.

Mean of 71.4 inches and a standard deviation of 3.1 inches.

This means that $\mu = 71.4, \sigma = 3.1$

a. What percentage of men have arm spans between 66 and 76 inches?

The proportion is the pvalue of Z when X = 76 subtracted by the pvalue of Z when X = 66. The percentage is the proportion multiplied by 100.

X = 76

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

$Z = \frac{76 - 71.4}{3.1}$

$Z = 1.48$

$Z = 1.48$ has a pvalue of 0.9306

X = 66

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

$Z = \frac{66 - 71.4}{3.1}$

$Z = -1.74$

$Z = -1.74$ has a pvalue of 0.0409

0.9306 - 0.0409 = 0.8997

0.8997*100% = 89.97%

89.97% of men have arm spans between 66 and 76 inches.

b. A particular professional basketball player has an arm span of almost 89 inches. Find the z-score for this person's arm span. What percentage of males have an arm span at least as long as this person?

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

$Z = \frac{89 - 71.4}{3.1}$

$Z = 5.68$

The z-score for this person's arm span is 5.68.

Z = 5.68 has a pvalue of 1

1 - 1 = 0

0% of males have an arm span at least as long as this person
