What is the length of the hypotenuse in the 30-60-90 triangle shown below?
30°
60°
6

Answer:

40 days saw either rain or high winds

Step-by-step explanation:

We solve this question using Venn sets.

I am going to say that:

Set A: Rain

Set B: High winds.

18 days saw rain

This means that [tex]A = 18[/tex]

29 days saw high winds

This means that [tex]B = 29[/tex]

7 days saw both rain and high winds.

This means that [tex]A \cap B = 7[/tex]

How many days saw either rain or high winds?

This is

[tex]A \cup B = A + B - A \cap B[/tex]

Sp

[tex]A \cup B = 18 + 29 - 7 = 40[/tex]

40 days saw either rain or high winds

Answer:

2/5

Step-by-step explanation:

Answer:

(-2, -7), (0, -3), (2, 1)

Step-by-step explanation:

Equation is given as y = 2x - 3.

To complete the table, plug in each value of x into y = 2x - 3 to get their corresponding y-value.

✔️When x = -2:

y = 2(-2) - 3

y = -4 - 3

y = -7

✔️When x = 0:

y = 2(0) - 3

y = -3

✔️When x = 2:

y = 2(2) - 3

y = 4 - 3

y = 1

Answer: 75 coins total, 51 nickels and 24 dimes.

Step-by-step explanation:

Answer:

For x – 4 to be a factor, you must have x = 4 as a zero. Using this information, I'll do the synthetic division with x = 4 as the test zero on the left:

Answer:

scalene right

Step-by-step explanation:

A scalene right has no equal side lengths, has a right side(90) and will have two angles less than 90 because all three triangle sides need to equal to be 180. So scalene right is your answer. Hope that helped!

Answer:

A is correct.

Step-by-step explanation:

Here, the x would represent the gallons per minute. The minutes are unknown, so it's just a variable. It can't be B either, because the addition sign would mean that the pool is being filled instead of drained.

Answer:

[tex] \therefore x =2[/tex]

Step-by-step explanation:

[tex] \triangle TPR \sim \triangle SQR... (given) [/tex]

[tex] \therefore \frac{TP}{SQ} = \frac{PR}{QR}[/tex]

[tex] \therefore \frac{TP}{SQ} = \frac{PQ+QR}{QR}[/tex]

[tex] \therefore \frac{3}{x} = \frac{1\frac{1}{3} +2 \frac{2}{3}}{2 \frac{2}{3}}[/tex]

[tex] \therefore \frac{3}{x} = \frac{\frac{4}{3} + \frac{8}{3}}{\frac{8}{3}}[/tex]

[tex] \therefore \frac{3}{x} = \frac{\frac{12}{3}}{\frac{8}{3}}[/tex]

[tex] \therefore \frac{3}{x} = \frac{12}{8}[/tex]

[tex] \therefore x = \frac{8\times 3}{12}[/tex]

[tex] \therefore x = \frac{24}{12}[/tex]

[tex] \therefore x =2[/tex]

Answer:

The answer will be 2

Step-by-step explanation:

The way you find the answer is by multiplying the numbers (simplifying)

Canceling both of the fives and adding the two negative signs together would leave you with the product of 2

i asked my dog:))

Answer:

The 95% confidence interval is "87.94, 91.86".

Step-by-step explanation:

The given values are:

Sample batches,

n = 25

Sample mean concentration,

[tex]\bar{x}[/tex] = 89.9 mg

Amount of chemical,

σ = 5

α = 0.05

The critical value from Z table will be:

=  [tex]Z(\frac{\alpha}{2} )[/tex]

=  [tex]Z(\frac{0.05}{2} )[/tex]

=  [tex]1.96[/tex]

Now,

The confidence interval will be:

=  [tex]\bar{x} \pm Z(\frac{\alpha}{2} )\times \frac{\sigma}{\sqrt{n} }[/tex]

On substituting the values, we get

=  [tex]89.9 \pm Z(\frac{0.05}{2})\times \frac{5}{\sqrt{25}}[/tex]

=  [tex]89.9 \pm Z(\frac{0.05}{2})\times \frac{5}{5}[/tex]

=  [tex]89.9 \pm1.96\times 1[/tex]

Lower limit will be:

=  [tex]89.9 -1.96\times 1[/tex]

=  [tex]87.94[/tex]

Upper limit will be:

=  [tex]89.9 +1.96\times 1[/tex]

=  [tex]91.86[/tex]

Answer:

The pulse rate is 84.54bpm

Step-by-step explanation:

Given

[tex]\^{} y = 17.8 + 0.940x[/tex]

Required

Find [tex]\^{}y[/tex] when [tex]x = 71[/tex]

Substitute 71 for x in: [tex]\^{} y = 17.8 + 0.940x[/tex]

[tex]\^{} y = 17.8 + 0.940 * 71[/tex]

[tex]\^{} y = 17.8 + 66.74[/tex]

[tex]\^{} y = 84.54[/tex]

The pulse rate is 84.54bpm

Answer:

[tex]A" = (3,2)\ \ B" = (-1,1)\ \ C" =(-3,4)\ \ D =(-1,4)[/tex]

Step-by-step explanation:

Given [Missing]

[tex]A = (-3,4)[/tex]

[tex]B = (1,3)[/tex]

[tex]C =(3,6)[/tex]

[tex]D =(1,6)[/tex]

The first transformation: reflection across the y-axis.

The rule is: [tex](x,y)==>(-x,y)[/tex]

So:

[tex]A = (-3,4)[/tex] ==>[tex]A' = (3,4)[/tex]

[tex]B = (1,3)[/tex] ==> [tex]B' = (-1,3)[/tex]

[tex]C =(3,6)[/tex] ==> [tex]C' = (-3.6)[/tex]

[tex]D =(1,6)[/tex] ==> [tex]D' = (-1,6)[/tex]

Translation 2 units down

The rule is: [tex](x,y)==>(x,y-2)[/tex]

So:

[tex]A' = (3,4)[/tex] ==> [tex]A" =(3,4-2) =(3,2)[/tex]

[tex]B' = (-1,3)[/tex] ==> [tex]B" = (-1,3-2) = (-1,1)[/tex]

[tex]C' = (-3.6)[/tex] ==> [tex]C" = (-3,6-2) = (-3,4)[/tex]

[tex]D' = (-1,6)[/tex] ==> [tex]D" =(-1,6-2) = (-1,4)[/tex]

Hence:

[tex]A" = (3,2)\ \ B" = (-1,1)\ \ C" =(-3,4)\ \ D =(-1,4)[/tex]

Answer:

10 ft

Step-by-step explanation:

Use theorem pythagoras

Length = x

[tex] {x}^{2} = 8 {}^{2} + {6}^{2} \\ x = - 10 \\ x = 10[/tex]

the answer is 10 because length can't be in negative number

Answer:

27.7°

Step-by-step explanation:

To find m<A, apply trigonometric function.

Reference angle = A

Side length opposite to A = 20

Hypotenuse = 43

Apply SOH, which is:

[tex] Sin (A) = \frac{Opp}{Hyp} [/tex]

Plug in the values

[tex] Sin (A) = \frac{20}{43} [/tex]

[tex] A = sin^{-1}(\frac{20}{43}) [/tex]

A ≈ 27.7° (nearest tenth)

Answer:

1. p value = 0.0203

2. We conclude that the market share for cars are different from what was suggested by the nation wde sales in 2017

Step-by-step explanation:

first we solve for the chisquare of this data.

from the attachment i have uploaded, a table of the ch square that i calculate gave:

Chisquare = 14.99

n = 7

degree of freedom = 7-1 = 6

we formulate hypothesis

H0; no diference in market share

H1: there is difference in market share

alpha = 0.05

we find the p value using the excel formula

CHIDIST(14.99, 6)

p value = 0.0203

the p value lies between 0.01 and 0.025

so we reject null and conclude that market share for for cars are different from what is suggested by nationwide sales in 2017

Answer:

Four (4); 45; at least; 181.

Step-by-step explanation:

Ali has four friends that owe him x dollars each. His parents owe him $45 for doing chores last week. He recalls that people owed him at least $181.

To find how much money each of Ali's friends owe him;

Given the algebraic expression;

4x + 45 ≤ 181

4x ≤ 181 - 45

4x ≤ 36

Dividing both sides by 9, we have;

x ≤ 9

Therefore, Ali's friends owe him at least $9 each.

Answer:

Four (4); 45; at least; 181.
