Select the inequality that best represents the graph.

Aleksandr [31]

Answer:

The answer is A) x is less than or equal to 4

Step-by-step explanation:

The arrow in pointing to the left, which means that the answer, "x", is smaller than 4. The dot being shaded means that 4 could be an possible answer too. (If the dot is shaded, it means that the number on the dot could be an answer while if the dot is not shaded, it means that the number that the dot is on can not be an possible answer)

There are 40 animals at a petting zoo.
Adult goats→x                   Child goats→a
Adult rabbits→y                 Child rabbits→b
<span>
There are twice as many adult rabbits as adult goats: y=2x
</span>There are three times as many child goats as adult goats: a=3x<span>                   There are exactly as many adult rabbits as there are child rabbits: b=y=2x

x+y+a+b=40⇒x+2x+3x+2x=40
8x=40⇒x=40/8⇒x=5

There are 5 </span><span> adult goats are in the petting zoo.</span>

Use De Morgan's laws to write negations for the statement. Sam is an orange belt and Kate is a red belt.

iVinArrow [24]

Answer:

C. Same is not an orange belt and Kate is not a red belt.

Step-by-step explanation:

A negation is an operation that "takes a statement and changes it to a statement whose true or false value is opposite". For example, if I were to say 2 + 2 = 4, the negation would be that 2 + 2 ≠ 4.

So, if Sam is an orange belt and Kate is a red belt, the negation is C. Same is not an orange belt and Kate is not a red belt.

Hope this helps!

Engineers must consider the breadths of male heads when designing helmets. The company researchers have determined that the popu

GenaCL600 [577]

Answer:

a) min = 4.4251

b) max = 8.5743

Step-by-step explanation:

Given:

Mean, u = 6.5

Standard deviation = 1

To get our values, we are to use the inverse of the standard normal table.

a) The minimum head breadth that will fit.

P(Z < z) = 1.9%

P(Z < z) = 0.019

P(Z < -2.0749) = 0.019

z = -2.0749

From the z-score formula, we have:

$\frac{x - \mu}{\sigma} = Z_0_._0_1_9$

Let x be the breath of heads.

Making x the subject of the formula, we have:

$x = z * \sigma + \mu$

We already have:

z = -2.0749

u = 6.5

s.d = 1

Substituting figures, we have:

x = (-2.0749 * 1) + 6.5

x = 4.4251

The minimum head breadth that will fit the clientele is 4.4251

b) The maximum head breadth that will fit.

P(Z > z) = 1.9%

1 - P(Z < z) = 0.019

P(Z < z) = 1 - 0.019 = 0.981

P(Z < 2.0749) = 0.981

From the z-score formula, we have:

$\frac{x - \mu}{\sigma} = Z_0_._0_1_9$

Let x be the breath of heads.

Making x the subject of the formula, we have:

$x = z * \sigma + \mu$

We already have:

z = 2.0749

u = 6.5

s.d = 1

Substituting figures, we have:

x = (2.0749 * 1) + 6.5

x = 4.4251

x = 8.5743

The maximum head breadth that will fit the clientele is 8.5743
