Which value of y would make OP ll LN? A 16 B 24 C 32 D 36

Andreyy89

see the attached figure to better understand the problem

we know that

if OP ll LN

then

by proportion

$\frac{MO}{ML} =\frac{MP}{MN}$

we have that

$MO=28\ units \\ML=28+14=42\ units\\MP=y\ units\\MN=(y+18)\ units$

substitute

$\frac{28}{42} =\frac{y}{(y+18)}\\ \\28(y+18)=42y \\ \\42y-28y=28*18 \\ \\14y=504 \\ \\y=36\ units$

therefore

<u>the answer is</u>

The value of y is $36\ units$

Ms. Davenport bought a dozen packages of spaghetti sauce mix priced at 3 packages for $1.29. What is the price of one package of

Verdich [7]

To find this out you would have to divide 1.29 by three to get the price for one. 1.29/3=.43. So the price for one spaghetti sauce mix is .43$ or 43 cents. Hope this helps.

A researcher is interested in consumer preferences among three brands of yogurt. A sample of 90 people is obtained,

ioda

Answer:

Step-by-step explanation:

From the given information:

The null hypothesis: all three brands are equally likely to their expected value

The alternative hypothesis: preferences exist among the three brands i.e. at least one is different from the expected value.

The expected frequency = $f_e$

The observed frequency = $f_o$

$f_e$ $f_o$ $(f_o- f_e)^2$ $\dfrac{(f_o - f_e)^2}{f_e}$

37 30 49.00 1.633

21 30 81.00 2.700

32 30 4.00 0.133

$X^2 = \sum\dfrac{(f_o-f_e)^2}{f_e} = 4.47$

Degree of freedom = $(n-1)$

= 3 -1

= 2

At ∝ = 0.05 and df = 2

The critical value $X^2_{0.05, 2}= 5.99$

Decision rule:

Since the calculated chi-square is less than the critical value, we do not reject the null hypothesis.

Thus, the null is retained with a calculated chi-square value of 4.47 and a critical chi-square value of 5.99.
