A basket contains 3/8 as many oranges as apples and three over four as many oranges as pairs what is the ratio of the number of
Gennadij [26K]
# of apples

3/8(a)=# of oranges

p=# of pears

3/4(p)=# of oranges

(3/8)a=(3/4)p

(3/8)/(3/4)=p/a

(3/8)(6/8)=p/a

3/6=p/a

1/2=p/a

the ratios of pears to apples is 1 to 2

for every 1 pear there are 2 apples

if there are 4 pears there are 8 apples

there are 8 apples

(3/8)(8)=3 oranges

there are 4 pears

(3/4)(4)=3 oranges again

8 apples, 3 oranges, 4 pears

15 pieces of fruit and 3 are oranges

ratio is 3/15=1/5

The Mean Corporation's statisticians would like to construct a hypothesis test for the mean annual profit (μ) earned by health-d
Jobisdone [24]

Missing Part of Question

Juice that is opened. It is known that the annual profits earned by health-drink franchises has a population standard deviation of $8,700

........

Answer:

z = 1.157

Step-by-step explanation:

Given

Annual profit as calculated = $90,300.

H0: μ = 89,000

Ha: μ > 89,000

σ = 8700

n = 60

Calculate the test statistic (z) that corresponds to the sample and hypotheses.

Test statistic (z) is calculated by

z = (x - μ)/(σ/√n)

Where x = 90,300

μ = 89,000

σ = 8700

n = 60

z = (90,300 - 89,000)/(8700/√60)

z = 1.157443298866584

z = 1.157 ----- Approximated

The martinez family has a walkway around their swimming pool. the area of the walkway can
DiKsa [7]

The width of the walkaway be 4 feet.

<h3>What is Discriminant Formula?</h3>

The discriminant formula is used to determine the nature of the roots of a quadratic equation. The discriminant of a quadratic equationax^{2} +bx+c=0 is D =b^{2} -4ac

If D > 0, then the equation has two real distinct roots.

If D = 0, then the equation has only one real root.

Given that: Area\; of \;walkway,\; a(w)\;= 4w^{2} + 100 w

also, area of walkaway = 464 square feet.

So, 4w^{2} + 100 w =464

     4w^{2} + 100 w -464=0

Using Discriminant method,

a=4, b=100, c=-464

w= \frac{-b\pm\sqrt{b^{2}-4ac} }{2a}

w= \frac{-100\pm\sqrt{(100)^{2}-4*4*(-464)} }{2*4}

w= \frac{-100\pm\sqrt{17424} }{8}

So, w_1= \frac{-100+\sqrt{17424} }{8} \;\;\;\; w_2= \frac{-100-\sqrt{17424} }{8}

w_1= \frac{-100+132 }{8} \;\;\;\; w_2= \frac{-100-132}{8}

w_1 = 4 \;\;\;\; and \;\;\; w_2= -29

Hence the width of the walkaway be 4 feet.
