Y=-1/2x+6

Answer: 12 tigers

Step-by-step explanation:

Since the ratio of lions to tigers is 1:3, meaning that for every one lions there three tigers and there's 4 lions and for every one lion there 3 tigers so we need to mulitpy 4 by 3

4×3=12 meaning there 12 tigets in the zoo.

Answer:

There are 12 tigers!

Explanation:

Let the tigers be X.

The ratio is 1:3, so it means that 1:3 = 4:X

1 x X = 3 x 4

X = 12

So, there are 12 tigers.

Have a good day!

Step-by-step explanation:

Answer:

75%

Step-by-step explanation:

The computation of the percent of the professional professors there are tenured is shown below;

Given that

academic professors A = 60%

professors  tenured P = 70%

professors at Paracelsus University = 90%

Based on the above information

As we know that 90% of the professors could be academic professors or tenured or both

so  here we can say that the percent of academic professors  is

= 60 + 70 - 90

= 40

Therefore professors  tenured will be

= 70 - 40

= 30

Now the percentage of professional professor that is tenured is

= 30 ÷ 40 × 100

= 75%

Answer:

The first one

Step-by-step explanation: the ABC triangle has a 25-degree angle and a 90-degree angle as you can see by the marks. The first triangle has a 25-degree angle and a 90-degree angle as you can see by the marks. The second one does have a 90-degree angle but it's a different shape and has no 25-degree angle. The third one has both angles 25 and 90 but if you look close it's a different shape. The last one does not have a 90-degree angle but it does have a 25-degree angle and it's a different shape.

So it would be the first option.

Step-by-step explanation:

Answer:

x = 9.4868

Step-by-step explanation:

For this problem we can use the Pythagorean Theorem

Pythagorean theorem = [tex]a^2+b^2=c^2[/tex]

IN THIS CASE C = X

A and B are the side and base lengths of a right triangle.

C is the Hypotenuse side.

[tex]9^2+3^2=c^2[/tex]

Solve...

81 + 9 = [tex]c^2[/tex]

90 =[tex]c^2[/tex]

[tex]\sqrt{90}[/tex] = c

c = 9.4868

Answer:

Step-by-step explanation:

The area for the sector of a circle is

[tex]A_s=\frac{theta}{360}*\pi r^2[/tex]  where theta is the measure of the central angle. We have some given values to fill in:

Area is 64π and the central angle is 90°, so all we have left to find is the radius. Filling into the equation:

[tex]64\pi =\frac{90}{360}*\pi r^2[/tex]

Let's get that solved for r-squared first:

[tex]\frac{360(64\pi )}{90\pi } =r^2[/tex]

Doing all the math on that gives us:

[tex]256=r^2[/tex]

Take the square root of both sides and get that r = ±16. BUT we know that lengths cannot be negative, so we disregard the -16 and say that the radius is 16 inches.

H  mean of data for store 1 is greater than mean for store 2

Step-by-step explanation:

mode for store 1 = 3

mode for store 2 = 2

range for store 1 = 6

range for store 2 = 6

mean for store 1 = 3.3125

mean for store 2 = 2.588

median for store 1 = 3

median for store 2 = 2

Answer:

-6

Step-by-step explanation:

Let the number be 'x'

Sum of a number and one = x + 1

Sum of a number and one is doubled = 2*(x +1) = 2*x + 2*1 = 2x + 2

Four less than the number = x - 4

2x + 2 = x - 4

Subtract 'x' from both sides

2x - x + 2 = x - x - 4

x + 2 = -4

No, subtract 2 form both sides

x + 2 -2 = - 4 - 2

x = -6

Answer:

5 1/6

Step-by-step explanation:

Answer:

Step-by-step explanation:

According to Angle sum property of triangle,

x + 45° + 85° = 180°

=> x = 180 - 85 - 45

=> x = 180 - 130

=> x = 50

Hence,

The missing angle x is 50° (Ans)

Answer:

45+85+x=180(sum of angle of triangle)

or, 130+x=180

or, x=180-130

x=50

Step-by-step explanation:

here, the sum of angle of triangle is 180

Answer:

b. If there is a linear relationship between the amount of mercury in a lake and the surface area of the lake, the probability of observing a test statistic of 2.086 is 0.05.

( the null is rejected and alternate is accepted)

Step-by-step explanation:

Here the critical value is t≥ t∝/2(n-2) = ± 2.086

The significance level is ∝= 0.05 and  the p- value is also 0.05

Which indicates that there is no correlation between the dependent and the independent variable.

If the p - value is less than 0.05 the null hypothesis is rejected.

There is a 5% chance that the  hypothesis is true.

So the null hypothesis should be rejected.

Given these options

a) if------as 2.086 or more extreme is 0.05

2.086 or 0.05 is the same in this case one cannot be more extreme.

c)  of 2.086 or greater is 0.05.

b). If there is a linear relationship ------.

This is the alternate hypothesis.

0.05 is not greater than 2.086 in the given question

d)  If there is not a linear relationship between the amount of mercury in-----.

This is the claim which is formulated as null  hypothesis.

e) if----  2.086 or more extreme is 0.05.

0.05 is the same as 2.086

At p- value 0.05 we reject the null hypothesis and accept the alternate hypothesis

8 girls are there in Mrs. Sanchez' class.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Based on the given conditions, formulate

2 girls ⇒ 3 boys

X girls ⇒ 12 boys

3X = 12 × 2

⇒ 3X = 24

⇒ X = [tex]\frac{24}{3}[/tex]

⇒ X = 8

Hence, 8 girls are there in Mrs. Sanchez' class.

Answer:

  (a)  63.4 degrees

Step-by-step explanation:

Any of the trig relations can be used. Since the picture cuts off the value of the hypotenuse, we choose to use the adjacent and opposite sides.

  Tan = Opposite/Adjacent

  tan(L) = 6/3 = 2

  L = arctan(2)

  ∠L ≈ 63.4°

Answer:

a) m<F = 70

b) AB = 6

Step-by-step explanation:

a)

Since this is an isoceles triangle, the base angles are equal so:

2x + 40 = 180

2x = 140

x = 70

b)

Since all of the angles are equal, this is an equilateral triangle. This also makes all of the sides equal and the same.
